Test Suite

Test Status Code Input and Output
1   Pass
assert(isempty(regexpi(evalc('type det2'),'det *(')))

2   Pass
A = 23; abserr=abs(det(A)-det2(A)); relerr=abserr/abs(det(A)); assert(abserr<1e-10 | relerr<1e-10)

3   Fail
A = magic(2); abserr=abs(det(A)-det2(A)); relerr=abserr/abs(det(A)); assert(abserr<1e-10 | relerr<1e-10)

Error using assert The condition input argument must be a scalar logical. Error in Test3 (line 4) assert(abserr<1e-10 | relerr<1e-10)
