Hi Eliane,

Here is the code that does it

t = -1:0.01:1; % Set the limits of span
x = zeros(length(t),1); % Initialize an array with zeros
t1 = t>=-0.5 & t<0.5; % Find the indices between -0.5 and 0.5
x(t1) = cos(3*pi*t(t1)); % Assign those indices with cosine function
plot(t,x) % Plot the figure

Hope this helps.

Regards,

Sriram
