Since you gave us no information, then the error message itself tells you everything that you could be told.
In whatever file gtc21.m is, the variable generatorPolynomials is ostensibly a scalar integer which is greater than the number of elements in shiftedValues, which is ostensibly an array of some unknown size. The index exceeds the number of elements in the array.
What size is shiftedValues, and why is generatorPolynomials greater than the number of elements in it? Nobody knows. Is gtc21.m your file, or is it some third party file that's being called improperly somewhere? Nobody knows.

It is also possible that a value has been assigned to a variable named sum or to a variable named mod

That too.
In other words, somewhere there's an array, and somewhere there's an index. Either:
- the array is inappropriately sized for the index
- the index is inappropriate for the size of the array
- or the "array" isn't even supposed to be an array.
