Hi,

I'm using Eigen2 and I want a function to accept arbitrarily size matrices. But since the matrix size is specified as a template, I'm at a loss how to do this.

Any help is appreciated.

Example function taking any expression as argument:

Code: Select all

template
void foo(const MatrixBase& m)
{
   std::cout << "Here's your matrix expression:" << std::endl << m << std::endl;
}


If you want a function that accepts only plain matrices, just replace MatrixBase by Matrix and make it template in the 6 template parameters of Matrix...

Thanks for your reply.

I don't know the size of the matrix at compile time, so I presume I can't use that. And I'm only interested in plain Matrices.

Edit: Seems that using MatrixBase will solve the problem. But I don't think it's possible with Matrix.

Nevermind, I noticed I have to use Dynamic
