Test Status Code Input and Output
1   Pass
nocheat = isempty(regexp(evalc('type matched_op'),'([^f]eval|regexprep|inline|str2func)')); x = [1 2;3 4]; y = [1 2]; z_correct = [1 4;3 8]; assert(isequal(matched_op(x,y,'times'),z_correct) && nocheat)

ans = function_handle with value: @times

2   Pass
nocheat = isempty(regexp(evalc('type matched_op'),'([^f]eval|regexprep|inline|str2func)')); x = [10i]; y = [20]; z_correct = [-2i]; assert(isequal(matched_op(x,y,'ldivide'),z_correct) && nocheat)

ans = function_handle with value: @ldivide

3   Pass
nocheat = isempty(regexp(evalc('type matched_op'),'([^f]eval|regexprep|inline|str2func)')); x = reshape(1:4,[1 1 1 4]); y = (1:4).'; z_correct = reshape([2 3 4 5 3 4 5 6 4 5 6 7 5 6 7 8],[4 1 1 4]); assert(isequal(matched_op(x,y,'plus'),z_correct) && nocheat)
