Unable to perform assignment because the size of the left side is 4-by-4 and the size of the right side is 2-by-2. Error in patchworkMatrix (line 8) M((row-1)*Psize(1)+1:row*Psize(1),(col-1)*Psize(2)+1:col*Psize(2)) = varargin{P(row,col)}; Error in Test2 (line 5) assert(isequal(patchworkMatrix(P,m1,m2),M_correct))
3   Fail
P = [2 3 2 3]; m1 = 1; m2 = 2; m3 = 3; M_correct = [2 3 2 3]; assert(isequal(patchworkMatrix(P,m1,m2,m3),M_correct))

Assertion failed.
4   Fail

Unable to perform assignment because the size of the left side is 3-by-2 and the size of the right side is 2-by-3.

5   Pass

6   Pass
P = []; m = cell(100); assert(isempty(patchworkMatrix(P,m{:})))
