When I use
MatrixExp[m,v] to compute, the error given by mathematica is
MatrixExp: Unable to satisfy Tolerance -> 1.4901161193847656`*^-8 for parameter value 0.6180060729365491`.
Here the matrix m is a large SparseArray with dimension 98*98, so I can not attach it.
Could anyone tell me how to solve this problem? Thank you！
