Question

plot([0:1:8],[rectpulse(1,9)]’) and plot([0:1:8],ones(1,9)) will generate the same graph.

(a) True

(b) False

I have been asked this question in quiz.

My question is taken from Operations on Signals topic in section Digital Signal Processing of MATLAB

Answer 1

The correct choice is (a) True

For explanation: ‘rectpulse(1,9)’ generates a column vector of 9 1’s. Since we have transposed it, the resultant is a row vector of 9 1s. ‘ones(1,9)’ also generates 9 1’s as a row vector. Thus, the above codes will result in the same graph.
