Test Suite

Test Status Code Input and Output
1   Pass
x = [NaN 1 2 NaN 17 3 -4 NaN]; y_correct = [0 1 2 2 17 3 -4 -4]; assert(isequal(replace_nans(x),y_correct))

c = NaN 1 2 NaN 17 3 -4 NaN c = 0 1 2 NaN 17 3 -4 NaN c = 0 1 2 2 17 3 -4 NaN c = 0 1 2 2 17 3 -4 -4 y = 0 1 2 2 17 3 -4 -4

2   Pass
x = [NaN 1 2 NaN NaN 17 3 -4 NaN]; y_correct = [ 0 1 2 2 2 17 3 -4 -4]; assert(isequal(replace_nans(x),y_correct))

c = NaN 1 2 NaN NaN 17 3 -4 NaN c = 0 1 2 NaN NaN 17 3 -4 NaN c = 0 1 2 2 NaN 17 3 -4 NaN c = 0 1 2 2 2 17 3 -4 NaN c = 0 1 2 2 2 17 3 -4 -4 y = 0 1 2 2 2 17 3 -4 -4

3   Pass
x = [NaN NaN NaN NaN]; y_correct = [ 0 0 0 0]; assert(isequal(replace_nans(x),y_correct))

c = NaN NaN NaN NaN c = 0 NaN NaN NaN c = 0 0 NaN NaN c = 0 0 0 NaN c = 0 0 0 0 y = 0 0 0 0

4   Fail
x = [1:10 NaN]; y_correct = [ 1:10 10]; assert(isequal(replace_nans(x),y_correct))

c = 1 2 3 4 5 6 7 8 9 10 NaN

Output argument "y" (and maybe others) not assigned during call to "replace_nans". Error in Test4 (line 3) assert(isequal(replace_nans(x),y_correct))
