Q&A

When I use the piecewise function I get more columns in the output

+2
−3

I have this code

syms t 

y(t) = t*heaviside(t)*heaviside(1-t);

x(t) = piecewise(0<=t<=1,1,t<0,0,t>1,0);

l = -2:0.01:2;

disp(y(l));

disp(x(l));

and in the output, I get 2 vectors which is ok. But if you look at those vectors

Matlab output when applying the defined piecewise function

they don't have the same size and this is a problem because I want to find the convolution of the functions y(t) and x(t). When I use the piecewise function the output vector is bigger than the output vector of the function t*heaviside(t)*heaviside(1-t)?
