Test Suite

Test Status Code Input and Output
1   Fail
x = [1 5 2 4 3];n=1; y_correct = [1 3 5 3.5 2 3 4 3.5 3]; assert(isequal(stretch_it_out(x,n),y_correct))

y = 1.0000 3.0000 5.0000 5.0000 3.5000 2.0000 2.0000 3.0000 4.0000 4.0000 3.5000 3.0000 ans = 3 6 9

Assertion failed.

2   Fail
x = [1 5 2 4 3];n=2; y_correct=[1 2+1/3 3+2/3 5 4 3 2 2+2/3 3+1/3 4 3+2/3 3+1/3 3]; y=abs(stretch_it_out(x,n)-y_correct); assert(max(y)<1e-9)

y = 1.0000 2.3333 3.6667 5.0000 5.0000 4.0000 3.0000 2.0000 2.0000 2.6667 3.3333 4.0000 4.0000 3.6667 3.3333 3.0000 ans = 4 8 12

Matrix dimensions must agree. Error in Test2 (line 3) y=abs(stretch_it_out(x,n)-y_correct);

3   Fail
