Hi,
When using the Matlab function iradon, one can choose an output size in the input syntax. However, this size has to be square (N x N).
For my application, performance is of the essence. For an input of 4000 pixels and 60 angles, I need to recover a reconstruction with a size of 4000x200 pixels as fast as possible. Obviously, I could ask iradon to generate a square reconstruction of 4000 x 4000 and then discard the part I don't need. This is however a waste of computing time.
Thanks in advance for any suggestion
