	)

inlinestatic

Calculate the position where the average is calculated.

It follow the same concept of central derivative

Parameters

pos	position where we are calculating the derivative
gs	Grid info
s_pos	staggered position of the properties

	)

inlinestatic

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	It is the map explained in FDScheme
kmap	position where the average is calculated
gs	Grid info
cols	non-zero colums calculated by the function
coeff	coefficent (constant in front of the derivative)
