Possibly you are running Octave code: delay is an Octave function, but it is not a MATLAB function.
The correct MATLAB function may be pause. Try it.
Or maybe delay is a local function or other third-party function that your code requires, but that is not located anywhere on the MATLAB path. In this case, find the file and put it on the MATLAB path.

In MATLAB, use the pause function.
