I have a 256x256 rectangle with all entries being zero.
So far I Have:
figure
R=Pb2_rect; (This file was provided from my professor)
imshow(Pb2_rect)
title('256x256 Projection')
colorbar
theta=0;
The image is
My task is to: Plot the projections of this rectangle for theta= 0, theta= 90 (see also function “radon” in matlab).
How do I do that?

I did look at that, but the radon function uses a range for theta, whereas in this exercise example I am only using one angle.

The documentation says that theta can be of types numeric scalar, numeric vector or gpuArray. So, you should be able to give one angle as an input to the function.
