Test Suite

Test Status Code Input and Output
1   Pass
p1=[1 2 3]; p2=[2 4 6]; y_correct = true; assert(isequal(isparallel(p1,p2),y_correct))

k = 0 0 0 y = logical 1

2   Pass
p1=[1 2 3]; p2=[2 5 6]; y_correct = false; assert(isequal(isparallel(p1,p2),y_correct))

k = -3 0 1 y = logical 0

3   Fail
p1=[666 911]; p2=[0.1 0.1*911/666]; y_correct = true; assert(isequal(isparallel(p1,p2),y_correct))

Error using cross (line 25) A and B must be of length 3 in the dimension in which the cross product is taken. Error in isparallel (line 2) k = cross(p1,p2) Error in Test3 (line 4) assert(isequal(isparallel(p1,p2),y_correct))

4   Fail
p1=[1 2 3]; p2=[0 0 0]; y_correct = false; assert(isequal(isparallel(p1,p2),y_correct))

k = 0 0 0 y = logical 1

Assertion failed.
