Not enough input arguments. Matrix must be square. Right hand side must be a column vector of length {0,number,integer} to match the coefficient matrix. Right hand side must be a column vector. Input tol may not be achievable by GMRES.\n Try to use a bigger tolerance. Input tol is bigger than 1. \n Try to use a smaller tolerance. RESTART is {0,number,integer} but it should be bounded by SIZE(A,1).\n Setting RESTART to {1,number,integer}. MAXIT is {0,number,integer} but it should be bounded by SIZE(A,1).\n Setting MAXIT to {1,number,integer}. Preconditioner must be a square matrix of size {0,number,integer} to match the problem size. Preconditioner must be a square matrix of size {0,number,integer} to match the problem size. Initial guess must be a column vector of length {0,number,integer} to match the problem size. Too many input arguments.
