Test Status Code Input and Output
1   Pass
%% M = 1:10; e = 1; M_corr = [2,2,4,4,6,6,8,8,10,10]; assert(isequal(evened_up(M,e),M_corr))

2   Pass
%% M = 1:10; e = 0; M_corr = [1,3,3,5,5,7,7,9,9,11]; assert(isequal(evened_up(M,e),M_corr))

3   Fail
%% M = 20:3:50; e = 1; M_corr = [20,24,26,30,32,36,38,42,44,48,50]; assert(isequal(evened_up(M,e),M_corr))

Assertion failed.

4   Fail

Assertion failed.

5   Fail
%% M = 2:2:100; e = 1; M_corr = M; assert(isequal(evened_up(M,e),M_corr))

Assertion failed.

6   Fail
%% M = 2:2:100; e = 0; M_corr = M+1; assert(isequal(evened_up(M,e),M_corr))

Assertion failed.

7   Fail
%% M = ones(3); e = 1; M_corr = M*2; assert(isequal(evened_up(M,e),M_corr))

Matrix dimensions must agree.

8   Fail
%% M = magic(3); e = 0; M_corr = [9,1,7;3,5,7;5,9,3]; assert(isequal(evened_up(M,e),M_corr))

10   Fail
%% M = eye(4); e = 1; M_corr = M*2; assert(isequal(evened_up(M,e),M_corr))

Matrix dimensions must agree.

11   Fail
%% M = eye(4); e = 0; M_corr = ones(4); assert(isequal(evened_up(M,e),M_corr))

Matrix dimensions must agree.

12   Fail
