Vertex with ID {0,number,integer} does not exist in that graph; perhaps it has been removed. The graph this vertex belongs to no longer exists. The graph this edge belongs to no longer exists. Vertex contains no data. Edge contains no data. Invalid edge. The target vertex does not exist. Invalid edge. The source vertex does not exist. No edge from vertex ID {0,number,integer} to vertex ID {1,number,integer} in that graph. Vertex with descriptor {0,number,integer} does not exist in that graph; perhaps it has been removed.

Please specify a valid number of bytes: {1}. Vertex ID cannot be empty. Please use a numeric type such as double or int32. Cannot create vertex IDs from data of type {0}. Please use a numeric type such as double or int32. There can be no edge between vertices {0,number,integer} and {1,number,integer}, because one of them is an invalid vertex. Valid vertex ID range: {2,number,integer} to {3,number,integer}. Wrong number of properties. Got: {0,number,integer}. Expecting: {1,number,integer} or 1. Wrong number of values. Got: {0,number,integer}. Expecting: {1,number,integer} or 1. The graph is empty. Add vertices and edges. The graph has no edge from vertex {0,number,integer} to vertex {1,number,integer}. Call Graph's add_edge function to add this edge before attempting to reference it. Argument {0,number,integer} must be a scalar. It is a {1,number,integer}-dimensional array. Argument {0,number,integer} must be numeric. Found a {1} instead. Please specify the traversal event. Possible values include 'DiscoverVertex' (first time vertex is visited) and 'BackEdge' (when a cycle is detected) -- see the documentation for the complete list. See this Visitor's ActiveEvents property for a list of events for which data is currently available. Expecting a character vector for the name of the traversal event. You provided an object of type {0}. Expecting a character vector for the name of the part property. You provided an object of type {0}.

Internal error: Vertex or edge predicate unexpectedly NULL. Operation cancelled. Predicate argument must be a function returning a boolean. You provided an object of type {0}. The predicate function requires {0,number,integer} inputs, but a part only has {1,number,integer} available. Please modify the predicate so that it has at most {2,number,integer} inputs. Too many MATLAB structure arrays in the argument list. The argument list may contain at most one MATLAB structure array, which will be used to set user data. Argument {0,number,integer} may not be structure array -- please eliminate it or change its type. Too many MATLAB double arrays in the argument list. The argument list may contain at most one MATLAB double array, which will be used to set values. Argument {0,number,integer} may not be a double array -- please eliminate it or change its type. Argument type mismatch: input number {0,number,integer} is a cell array, but the findIf search data is already set. Only one input to findIf may be a cell array. Argument type mismatch: input number {0,number,integer} is a character vector, but the findIf part type is already set. Only one input to findIf may be a character vector, and it must specify either 'edge' or 'vertex'. Argument type mismatch: input number {0,number,integer} is numeric, but not scalar (it has {1,number,integer} elements). Only one input to findIf may be numeric and it must be a scalar: the maximum number of parts to return.

You requested {2,number,integer}. Graph part type must be either 'vertex' or 'edge'. You specified "{0}". The start and finish vertex lists may be scalars or vectors (1xN or Mx1). If both are non-scalar, they must contain exactly the same number of elements. Please note that they do not. length(start): {0,number,integer}. length(finish): {1,number,integer}. The values array and the data array may be scalars or vectors (1xN or Mx1). If both are non-scalar, both must be exactly the same size. That hasn't happened here. length(values): {0,number,integer}. length(data): {1,number,integer}. Expecting a 1xN or Nx1 structure array for the user data of the new vertices.

You provided an object of type {0}. Expecting a 1xN or Nx1 character vector. You provided a {0,number,integer}-dimensional array whose first two dimensions are {1,number,integer}x{2,number,integer}. Argument {0,number,integer} must be a structure. Argument {0,number,integer} of {1} must be a {2}. You provided a {3}. Type mismatch at argument {0,number,integer}. This function does not accept arguments of type {1}. Argument {0,number,integer}: provide a structure array to specify data or a double array to set values. Incorrect type: {1}. No such event {0} for {1} graph traversals. Please specify a valid event. If you're going send a {0} to visit a graph, you need to specify the graph. Please call visit() with two arguments: the visitor object and the graph. For example: values = visit(visitor, graph). You cannot ask a visitor for the vertices it has visited until you send it to visit a graph. This {0} has never visited a graph. If you have a graph g, and a visitor v, call visit(v, g) to initiate a graph traversal. You cannot ask a visitor for the values collected during a graph traversal until you send it to visit a graph. This {0} has never visited a graph. If you have a graph g, and a visitor v, call visit(v, g) to initiate a graph traversal. When you create a {0} visitor, you may specify an array of callbacks that the visitor will invoke a pre-determined times during the graph traversal. The callback array must be a structure with three fields: 'event', 'callback' and 'state'. Only 'state' may be empty. The function {0} requires {1} arguments. You provided {2,number,integer}. The program {0} requires {1,number,integer} arguments. You provided {2,number,integer}. The constructor for {0} requires {1} arguments. You provided {2,number,integer}. Unable to determine graph edge direction (directed or undirected) from inputs to {0}. Specify ('directed', true) for a directed graph or ('directed', false) for an undirected graph. Invalid input argument list for {0}. You provided data of type {0} for an operation that requires a numeric type. When you call {0} with {1,number,integer} arguments, you must specify either a number of vertices or a vector of edges. Neither could be located in the argument list. When you call {0} with {1,number,integer} arguments, one of them must be a MATLAB structure specifying user data. The argument list does not contain any MATLAB structures. Graph {0} visitor callback must return the state argument in order for state changes to persist. The callback should have this form: [value, state] = @(part, graph, state). (part is either a vertex or an edge, depending on the type of callback.) No data is available for {0} graph traversal callback {1}. Perhaps you did not specify a callback for this event? Insufficient memory to compute {0,number,integer}-piece transitive closure of graph with {1,number,integer} vertices and {2,number,integer} edges. Try splitting the graph into more pieces. Insufficient memory to grow results vector to {0,number,integer} elements. Operation cancelled.

Could not retrieve {0} data. Cannot serialize (save) graph. You can only set the vertex data of an empty graph. This graph already has {0,number,integer} vertices. Cannot initialize the {0} data because the input structure is empty or NULL. The {0} initialization data must be a MATLAB structure. You provided a {1}. Cannot initialize {0} data. The input structure is missing a required field: {1}. Cannot initialize the graph's {0} data. The {1} matrix has the wrong number of dimensions.

Cannot initialize the graph's {0} data. The input structure must have {1,number,integer} fields. The given structure has {2,number,integer} fields. You can only set the edge data of an unconnected graph. This graph already has {0,number,integer} edges. You cannot set the edge data of a graph with zero vertices. Please add vertices (perhaps by calling setVertexData) before adding edge data. The {1} field of the {0} structure has the wrong type. Expected: {2}. Found: {4,number,integer} {3}{5}.
