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

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)?

The first vector isn't shown completely in your screenshot. So it cannot show what it is intended to show according to the text.

You should have copy-pasted the output instead of posting a meaningless (and data wasting) screenshot.

Even better, post the actual length of the vectors instead of expecting us to count ourselves.

Don't you see? The screenshot clearly shows one vector ending before the other. Ignore the fact that the components of the vector take up different amounts of textual space...
