Test Suite

Test Status Code Input and Output
1   Fail
x = 0; y_correct = 2; assert(isequal(nearestprime(x),y_correct))

i = 0 j = 0

Error using isprime (line 19) All entries of X must be nonnegative integers. Error in nearestprime (line 7) while ~isprime(j) Error in Test1 (line 3) assert(isequal(nearestprime(x),y_correct))

2   Pass
x = 5; y_correct = 5; assert(isequal(nearestprime(x),y_correct))

i = 5 j = 5 y = 5

3   Pass
x = 100; y_correct = 101; assert(isequal(nearestprime(x),y_correct))

i = 100 j = 100 y = 101

4   Pass
x = 500; y_correct = 499; assert(isequal(nearestprime(x),y_correct))

i = 500 j = 500 y = 499

5   Pass
x = 911; y_correct = 911; assert(isequal(nearestprime(x),y_correct))

i = 911 j = 911 y = 911

6   Pass
x = 2500; y_correct = 2503; assert(isequal(nearestprime(x),y_correct))

i = 2500 j = 2500 y = 2503

7   Pass
x = 8000; y_correct = 7993; assert(isequal(nearestprime(x),y_correct))

i = 8000 j = 8000 y = 7993

8   Pass
x = 100000; y_correct = 100003; assert(isequal(nearestprime(x),y_correct))

i = 100000 j = 100000 y = 100003

9   Pass
x = 1300000; y_correct = 1299989; assert(isequal(nearestprime(x),y_correct))

i = 1300000 j = 1300000 y = 1299989

10   Pass
x = 179424710; y_correct = 179424719; assert(isequal(nearestprime(x),y_correct))

i = 179424710 j = 179424710 y = 179424719
