I need to do more tests.... but I am still unconvinced, MATLAB and python do, in fact, store memory in a different order, so if the CUDA code works, there...

OK, sorry, I understood it! MATLAB indexing goes ``, and python goes ``. The swap of memory layout happening because row/column major gets compensated because in MATLAB we call "X"...

@genusn no worries, its a reasonable mistake, it should be as you wrote logically, bur for some reason I decided to not do that back then. I think thats a...

@genusn ah that is correct. I'll try to modify that. Admittedly, MLEM is a bit out of place and never cared too much about it.... CT data can not really...

A better code to reproduce it: ``` %% Initialize clear; close all; %% Geometry geo=defaultGeometry(); %% Define angles of projection and load phatom image % define projection angles (in radians)...

@yliu88au no, not at all unfortunately. #335 is just a weight, while this mismatch is much smaller, yet it happens in the forward proejction, so its not weighted. I think...

@yliu88au no still not. In theory all the code should work with floats. But perhaps that makes all create this numerical error. I guess a test that I should carry...

This seems to come from floating point arithmetics. Someone proposed a way to solve it: In the geometric transform code of the GPU, do not translate directional vectors, only rotate...

Hi @ashwinpn , Yes, that is great! Please do a fork, then create a new branch and work there so you can do a Pull request when you think its...

Hi @tsadakane , it is not. In that work, a full C++ implementation was coded, particularly optimized for the size and amount of projections of the application. The code I...
