I guess the assignment should read:
assert(isequal(zigzag(a),y_correct))
While you are amending the Test Suite, please add more test cases (at least four), to ensure only general solutions are successful, not hard-coded submissions. (See Problem 44617 for further ideas.)
Please also check the Solution Template. Currently there is a lot of code in the Solution Template which everyone can see! Usually the Solution Template would be almost blank. —DIV
This problem has been fixed so that it (1) no longer displays a solution in the function template, (2) is solvable, and (3) has additional test cases added.
By the way, this problem is essentially identical to https://www.mathworks.com/matlabcentral/cody/problems/1167-matrix-zigzag.
@goc3: This two problems are not exactly identical, since this problem have a test(the last one) which contains 0 element, this pretty much change everything, if some particular function like nonzeros, etc is considered to be used.
@bainhome: then it's a good thing I added that extra test case to make the problems slightly different.
