Test Status Code Input and Output
1   Pass
x = 3; y_correct = true; assert(isequal(isMersenne(x),y_correct))

2   Pass
x = 127; y_correct = true; assert(isequal(isMersenne(x),y_correct))

3   Fail
x = 157; y_correct = false; assert(isequal(isMersenne(x),y_correct))

Error using isprime (line 19) All entries of X must be nonnegative integers. Error in isMersenne (line 3) if isprime(x) & isprime(log2(x+1)) & rem(x,1)==0 Error in Test3 (line 3) assert(isequal(isMersenne(x),y_correct))

4   Pass
x = 2047; y_correct = false; assert(isequal(isMersenne(x),y_correct))
