what is this error?

When I run the SPI calculation function this error was displayed.

function=" Z=SPI(Data,3,12) ;"

error=" * Maximum recursion limit of 1000 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware that exceeding your available stack space can crash MATLAB and/or your computer .

Error in gamrnd * "

Before run the function original data,i used this on to test the function.

 Z=SPI(gamrnd(1,1,1000,1),3,12);

what is the reason for this and how to solve this problem?

Inside SPI, it's calling itself. That's what recursion means. Why do you have it calling itself?
