Test Suite

Test Status Code Input and Output
1   Fail
A = randn(5,5); assert(isequal(arraySlice(A,4,2),A(:,4)))

dim = 5 1 S = 0.5561 -0.1631 0.3799 -0.4080 -0.4929

Assertion failed.

2   Fail
A = randn(5,5); assert(isequal(arraySlice(A,4,1),A(4,:)))

dim = 1 5 S = -1.5191 0.2297 0.0708 -1.2534 0.1785

Assertion failed.

3   Pass
A = randn(5,5); assert(isequal(arraySlice(A,1,10),A))

4   Fail
A = randn(5,5,5,3); assert(isequal(arraySlice(A,3,4),A(:,:,:,3)))

dim = 5 5 5 1

Error using reshape Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension. Error in arraySlice (line 13) S = reshape(S,dim) Error in Test4 (line 2) assert(isequal(arraySlice(A,3,4),A(:,:,:,3)))

5   Fail
A = randn(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2); assert(isequal(arraySlice(A,2,18),A(:,:,:,:,:,:,:,:,:,:,:,:,:,:,:,:,:,2)))
