I am trying to assign a value to a matrix position, such as:
pop[[ x,y ]] = value
in a module function. When I try manually assigning a value
to the matrix position outside of the module, it works. When
I run the function with the statement, Mathematica gives me
the following error message:
Part::setps:
{{1, 1, 0, 0}, <<1>>}
in assignment of part is not a symbol.
Can anyone tell me how to get the assignment statement to
work! I isolated the problem in the function to this line
and I am sure that what I just described was the problem.
I have tried using the command:
pop=ReplacePart[pop,value,{x,y}]
but it gives me even more error messages! Help me please!
I appreciate any help. Thanks.
