This function takes 3 inputs. The first argument is a matrix to be “trimmed”. The second argument is how many rows to trim, or remove from the top of the matrix. The third argument is how many rows to remove from the bottom of the matrix.

Either the second or third argument to trimr is negative. The error means that the program is trying to remove a negative number of rows from a matrix.

The fastest way to see what is going on is probably to stick a breakpoint on that call to trimr, then run the debugger to that point and see which value is negative. Then you can look backwards and see what went wrong.
