data=load('triplicado.txt');
I=input('Ingresa 1(lineal), 2(exponencial) ó 3(potencia)= ')
if I==1;
A=mincuad(x,y);
elseif I==2;
B=expo(x,y);
else
C=potencia(x,y);
end

When asking for help with an error, always give us the full text of the error message. Copy/paste everything in red.

Hi
This error is caused because you are attempting to reference a nonexistent element of an array.Common causes for this may be like changing the size of an array unexpectedly or encountering an empty array when you expected a nonempty array. Stop MATLAB on the line where the error occurs. Verify that the size of the array into which you are referencing is large enough so that the index you are using falls before the last element of the array.

Another common reason for this is that you've named a variable min or max or sum and are then trying to use the min or max or sum function but end up indexing your variable instead.
