### Test Suite

Test Status Code Input and Output
1   Pass
a = [1 2 3 4 5]; b = [2 3 4 5 6]; y_correct = [1 6]; assert(isequal(vector_diff(a,b),y_correct))

2   Fail
a = 10:-2:0; b = 1:2:11; y_correct = 0:11; assert(isequal(vector_diff(a,b),y_correct))

Error using histc Edge vector must be monotonically non-decreasing. Error in hist (line 152) nn = histc(y,edgesc,1); Error in vector_diff (line 4) count_x = hist(c,unique_x); Error in Test2 (line 4) assert(isequal(vector_diff(a,b),y_correct))

3   Fail
a=magic(5); b=magic(6); y_correct = 26:36; assert(isequal(vector_diff(a,b),y_correct))

Error using histc Edge vector must be monotonically non-decreasing. Error in hist (line 152) nn = histc(y,edgesc,1); Error in vector_diff (line 4) count_x = hist(c,unique_x); Error in Test3 (line 4) assert(isequal(vector_diff(a,b),y_correct))

4   Pass
a=(10:100)'; b=11:100; y_correct = 10; assert(isequal(vector_diff(a,b),y_correct))

5   Fail
a=magic(3)-1.5; b=[]; y_correct = -0.5:7.5; assert(isequal(vector_diff(a,b),y_correct))

Error using histc Edge vector must be monotonically non-decreasing. Error in hist (line 152) nn = histc(y,edgesc,1); Error in vector_diff (line 4) count_x = hist(c,unique_x); Error in Test5 (line 4) assert(isequal(vector_diff(a,b),y_correct))

6   Fail
a=zeros(5); b=ones(3); y_correct=[0 1]; assert(isequal(vector_diff(a,b),y_correct))

Assertion failed.

7   Pass
forbidden = '(regexp)'; assert(isempty(regexp(evalc('type vector_diff'),forbidden)));
