See:
help rand
% Generate values from the uniform distribution on the interval (a, b):
r = a + (b - a) .* rand(x, 1);
Now set a=-pi and b=p:
r = -pi + 2*pi * rand(x, 1);
Actually we do not solve homework questions in the forum. But here I hope you see, how useful the hint is to take a look into the documentation. For questions concerning a command, start with help() and doc(). If this does not help directly, look at the bottom in the "See also" line, which contains other similar commands.

x = ones(1,100); a = [rand(1,length(x))-0.5]+linspace(-pi+0.5,pi-0.5,length(x));
