Test Status Code Input and Output
1   Fail
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))

Assertion failed.

2   Fail
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))

Assertion failed.

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

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

Array indices must be positive integers or logical values. Error in replace_nans (line 12) x(j) = x(j-1); Error in Test4 (line 3) assert(isequal(replace_nans(x),y_correct))
