C/gmres algorithm

WebThe GMRES algorithm is typically used when the dimensions of the problem are very large, thus it is of interest to investigate ways in which the computational and memory cost of running it can be reduced. One method for doing so involves replacing the matrix-vector multiplications with an approximating function.
