Test Suite

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

y = logical 1

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

y = logical 1

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)==1 & isprime(log(x+1)/log(2))==1 Error in Test3 (line 3) assert(isequal(isMersenne(x),y_correct))

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

5   Pass
x = 8191; y_correct = true; assert(isequal(isMersenne(x),y_correct))

y = logical 1

6   Pass
x = 524287; y_correct = true; assert(isequal(isMersenne(x),y_correct))

y = logical 1

7   Pass
x = 536870911; y_correct = false; assert(isequal(isMersenne(x),y_correct))
