Here we solve tomographic problems without constructing the measurement matrix A at all.

Simulate tomographic data without inverse crime

This routine uses the radon.m function of Matlab's Image processing toolbox to create a sinogram:


Compute reconstruction using filtered back-projection


Compute reconstruction using matrix-free iterative Tikhonov regularization


Compute reconstruction using matrix-free iterative (approximate) total variation regularization

Here are the main computation and plot routines:
