Solve ill-conditioned linear systems
If b has no noise in it, you could try normalizing the rows of A a=vecnorm(A,2,2); A=A./a;b=b./a; x=A\b;

Error Using Reshape in MATLAB
By checking the size of "decoded_low" in line 26. You will see that it does not have the same number of elements as lenna_gray.

Uploading .mat files that contain nested structs into a datastore
I think the wisest course would be to reorganize your data and assign each "Unit" to its own separate .mat file.
