Original question:http://au.mathworks.com/matlabcentral/answers/281617-i-am-having-some-issues-calling-a-function-in-a-script-file One more question if you or anyone is still looking at this. In the original function the n number of outputs are arranged so that the index of the first is assigned to 1 on the plot created with my script. However since i'm dealing with populations I need this 'initial' value to be assigned to 0 on the plot. Or in other words, for every y value I have, the x value needs to decrease by 1. So my graph will be translated left 1 unit.
