Calculate which colums of the Matrix are non zero.

stub_or_real it is just for change the argument type when testing, in normal conditions it is a distributed map

Parameters

g_map	map grid
kmap	position in the grid
spacing	of the grid
gs	Grid info
cols	non-zero colums calculated by the function
coeff	coefficent (constant in front of the derivative)
