### Test Suite

Test Status Code Input and Output
1   Pass
a = [1 2 3 4]; b = [5 6 7 8]; y_correct = [1 5 2 6 3 7 4 8]; assert(isequal(merge(a,b),y_correct))

2   Pass
a = 1:2:10; b = 2:2:10; y_correct = 1:10; assert(isequal(merge(a,b),y_correct))

3   Pass
a = ones(1,5); b = 2*ones(1,5); y_correct = repmat([1 2],[1,5]); assert(isequal(merge(a,b),y_correct))

4   Fail
a = [1 2 3; 4 5 6]; b = [4 5 6; 7 8 9]; y_correct = [1 4 2 5 3 6; 4 7 5 8 6 9]; assert(isequal(merge(a,b),y_correct))

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 merge (line 2) c = reshape([a; b],1,2*length(a)); Error in Test4 (line 4) assert(isequal(merge(a,b),y_correct))

5   Fail
a = ones(3); b = eye(3); y_correct = [1 1 1 0 1 0; 1 0 1 1 1 0; 1 0 1 0 1 1]; assert(isequal(merge(a,b),y_correct))

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 merge (line 2) c = reshape([a; b],1,2*length(a)); Error in Test5 (line 4) assert(isequal(merge(a,b),y_correct))
