Test Status Code Input and Output
1   Pass
M = rand(4); a = [4 3 2 1]; b = [1 2 3 4]; v_correct = M([4 7 10 13]); assert(isequal(twoIndex(M,a,b),v_correct))

i = 4 7 10 13

2   Pass
M = rand(4); a = [3 3 1 3]; b = [1 1 3 1]; v_correct = M([3 3 9 3]); assert(isequal(twoIndex(M,a,b),v_correct))

i = 3 3 9 3

3   Pass
M = rand(100); [a,b] = size(M); v_correct = M(end); assert(isequal(twoIndex(M,a,b),v_correct))

i = 10000

4   Pass
M = rand(100); a = []; b = []; assert(isempty(twoIndex(M,a,b)))

i = []

5   Pass
M = 1; a = [1 1 1 1 1]; b = [1 1 1 1 1]; v_correct = [1 1 1 1 1]; assert(isequal(twoIndex(M,a,b),v_correct))

i = 1 1 1 1 1

6   Pass
filetext = fileread('twoIndex.m'); assert(isempty(strfind(filetext, 'for')),'for forbidden') assert(isempty(strfind(filetext, 'while')),'while forbidden')
