BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a

PADDEDSIZE Computes padded sizes useful for FFT-based filtering

RESSTR = padString(STRING, PADDING, DELIMITER, LENGTH) M-function pads STRING with PADDING characters after each DELIMITER to achieve LENGTH. Default PADDING is space. If DELIMITER is omitted, '\n' is used. If no LENGTH is provided, padding is perfor
