### Test Suite

Test Status Code Input and Output
1   Pass
filetext = fileread('addVecToMat.m'); assert(isempty(strfind(filetext, 'regexp')),'regexp hacks are forbidden')

2   Pass
mat = ones(2); v = 1:3; comb_correct = [1 1 inf; 1 1 inf; 1 2 3]; assert(isequal(addVecToMat(mat, v), comb_correct))

m = 2 n = 2 s = 3 comb = 1 1 Inf 1 1 Inf 1 2 3

3   Pass
mat = ones(3, 4); v = [2 3]; comb_correct = [ones(3,4); 2 3 -inf -inf]; assert(isequal(addVecToMat(mat, v), comb_correct))

m = 3 n = 4 s = 2 comb = 1 1 1 1 1 1 1 1 1 1 1 1 2 3 -Inf -Inf

4   Fail
mat = ones(2); v = [2 3]; comb_correct = [1 1; 1 1; 2 3]; assert(isequal(addVecToMat(mat, v), comb_correct))

m = 2 n = 2 s = 2 com = 1 1 1 1 2 3

Output argument "comb" (and maybe others) not assigned during call to "addVecToMat". Error in Test4 (line 4) assert(isequal(addVecToMat(mat, v), comb_correct))

5   Pass
mat = ones(3); v = 1:6; comb_correct = [repmat([ones(1,3) inf(1,3)], 3, 1); 1:6]; assert(isequal(addVecToMat(mat, v), comb_correct))

m = 3 n = 3 s = 6 comb = 1 1 1 Inf Inf Inf 1 1 1 Inf Inf Inf 1 1 1 Inf Inf Inf 1 2 3 4 5 6
