Test Suite

Test Status Code Input and Output
1   Fail
C=[4; 1; 2]; R=[2 3 5]; M=[8 12 20; 2 3 5; 4 6 10]; assert(isequal(mul(C,R),M));

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 mul (line 2) C=reshape(C',1,3,10); Error in Test1 (line 4) assert(isequal(mul(C,R),M));

2   Fail
C=[1; 1; 1]; R=[1 1]; M=ones(3,2); assert(isequal(mul(C,R),M));

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 mul (line 2) C=reshape(C',1,3,10); Error in Test2 (line 4) assert(isequal(mul(C,R),M));

3   Fail
C=[1;2;3;0]; R=[7,2]; M=[7 2; 14 4; 21 6; 0 0]; assert(isequal(mul(C,R),M));

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 mul (line 2) C=reshape(C',1,3,10); Error in Test3 (line 4) assert(isequal(mul(C,R),M));
