Fifth input FILLVALUE must be a numeric, logical, or char value, or a cell. Product of dimensions is greater than maximum integer. First input SUBS must contain positive integer subscripts. First input SUBS and third input SZ must satisfy ALL(MAX(SUBS)<=SZ). First input SUBS must contain numeric subscripts. Function ''sum'' is not defined for values of class {0}. Maximum variable size allowed by the program is exceeded. First input SUBS may not have more than 2 columns for sparse output. Fifth input FILLVALUE must be the real double value zero for sparse output. Input values for sparse accumulation must be double. Sparse matrix sizes must be non-negative integers. First input SUBS must be a real, full, numeric matrix with at least one column. First input SUBS must have at least one cell. Cells of first input SUBS must contain real, full, numeric vectors of equal length. Second input VAL must be a full numeric, logical, or char vector or scalar. Second input VAL must be a vector with one element for each row in SUBS, or a scalar. Second input VAL must be a vector with the same number of elements as each cell in SUBS, or a scalar. Third input SZ must be a full row vector with one element for each column of SUBS. Third input SZ must be a full row vector with one element for each cell of SUBS. When SUBS is a column vector, the third input SZ must be of the form [N 1]. Fourth input FUN must be a function handle. Fifth input FILLVALUE must be a full scalar. Fifth input FILLVALUE must be a numeric, logical, or char value, or a cell. Sixth input ISSPARSE must be a logical scalar. First input SUBS must be a real, full, numeric matrix or a cell vector. The function ''{0}'' returned a non-scalar value. The function ''{0}'' returned a sparse value. The function ''{0}'' returned a value that was not numeric, logical, char, or a cell. The function ''{0}'' returned values that did not all have the same class. FILLVALUE and output from the function ''{0}'' did not have the same class.
