Use Matlab and the commands $fft(),fft2(),$imrotate$()$ and griddata$(),$ to demonstrate the Central

Slice Theorem. Note that the projection operation can be simulated using the sum$()$ command along rows

or columns in an array that represents the object domain, and the imrotate$()$ command can be used to

rotate your array to change the angle used for the projection calculation. $($You should use the 'crop'

flag in imrotate$()$ to keep the array size from changing. This will work better if you keep all of your

nonzero object data inside a circle that is entirely inside your object array.$)$ The command griddata$()$

performs interpolation of data and can be used to interpolate polar data in the spatial frequency domain.
