Linear convolution program without using for loop construct

This small dsp program aims to perform linear convolution between two sequences without using for loop.

This small beginners project aim is to perform linear convolution between two sequences without using for loop. It comprises the respective m-files to start of MATLAB programming for new learners.

Convolution inputs may be given from command window. Above title figure example is computed for x(n)={1,2,3} & {1,2}.

Thank you.
