[Getfem-users] [GMM++] Resizing a matrix

[Fem Dev]

Hello again,

I have another question about GMM++. I want to resize a matrix without keeping 
old entries in it. In fact, all the entries have to be reset to zero.
The documentation says:


MATRIX_TYPE M(m1, n1);
.... your code
std::swap(M, MATRIX_TYPE(m2, n2)); // resize matrix M.My example code looks 
almost the same:

gmm::dense_matrix<double> A(84,84);
//...
std::swap(A, gmm::dense_matrix<double>(24, 24))


The compiler returns this error:
...\..\main.cpp no matching function for call to 
`swap(gmm::dense_matrix<double>&, gmm::dense_matrix<double>)' 

So, what wrong with it? Thanks a lot for your help.

Regards.
