Would it be possible to use this program to forward project a 3D image where dx=dy, but dx=dy!=dz? Right now, my parameters are:

%% Parameter setting %%

param.nx = 400;
param.ny = 400;
param.nz = 66;

%The real detector panel pixel density (number of pixels)
param.nu = 400;
param.nv = 400;

% Detector setting, according to Varian Trilogy OBI (real size)
param.su = 350; % mm
param.sv = 350; % mm

% X-ray source and detector setting
param.DSD = 1500; % Distance source to detector
param.DSO = 1000; % X-ray source to object axis distance

% This confusing stuff
% (1000/1500)*(350/400)
param.sx = param.nx*res; % mm
param.sy = param.ny*res; % mm
param.sz = param.nz*res; % mm

but this doesn't create the correct forward projections, so far as I have been able to check. Am I trying to do something that is impossible in image processing?

Thank you!

Hi, I am trying to run a stepper motor using a seeedstudio motor shield v1.0 paired with an arduino uno, and it is totally fine running the stepper in the arduino IDE but I haven't managed to budge it using MATLAB. I have been successful moving servos and reading analog voltages through MATLAB, so maybe the problem is the motor shield?
Any help would be greatly appreciated!
