Test Status Code Input and Output
1   Pass

2   Fail
x = 2:2:20; y_correct = 0; assert(isequal(locOf5(x),y_correct))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in locOf5 (line 7) y(j) = find( x(:,i) == 5); Error in Test2 (line 3) assert(isequal(locOf5(x),y_correct))

3   Fail
x = rot90(1:10); y_correct = 6; assert(isequal(locOf5(x),y_correct))

Assertion failed.

4   Fail
x = [1 2 5 5 9 1 5 6 5]; y_correct = [2 0 1]; assert(isequal(locOf5(x),y_correct))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in locOf5 (line 7) y(j) = find( x(:,i) == 5); Error in Test4 (line 5) assert(isequal(locOf5(x),y_correct))

5   Fail
x = magic(5); y_correct = [0 2 0 0 0]; assert(isequal(locOf5(x),y_correct))

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side. Error in locOf5 (line 7) y(j) = find( x(:,i) == 5); Error in Test5 (line 3) assert(isequal(locOf5(x),y_correct))

Unable to perform assignment because the left and right sides have a different number of elements. Error in locOf5 (line 7) y(j) = find( x(:,i) == 5); Error in Test6 (line 7) assert(isequal(locOf5(x),y_correct))
