Hi,
I have a 91282 x 1 matrix and I want to replace the specific values 59688:60003 (n=315) with another set of 315 numbers (a 315 x 1 matrix) in those exact places. What is the best way of doing this? Thanks!

Try this
% Stuff sourceVector into indexes 59688:60003 of targetVector
targetVector(59688:60003) = sourceVector;

@bsriv: Note that 59688:60003 has 316 elements, not 315. So if you want to insert 315 elements starting from element 59688:
len = numel(sourceVector);
targetVector(59688:(59688 + len - 1)) = sourceVector;
% ^^^ essential!

You can use the intlut() function.
