Hi, which language are you using, MATLAB, FORTRAN, C, ...?

Santhosh Sankar

Use numpy from python. Very easy.

Hi, I am not a specislist in Python but it is possible to read the matrix from an input file. See the following link to the dicumentation:

https://docs.scipy.org/doc/numpy-1.12.0/user/basics.creation.html

Another possibility would be that a partcular structure exists in your matrix that allows building it automatically using some lines of Python code.
