### Test Suite

Test Status Code Input and Output
1   Pass
filetext = fileread('vmultiply.m'); assert(isempty(strfind(filetext,'regexp'))) assert(isempty(strfind(filetext,'switch')))

2   Fail
v1 = [1 2]; v2 = [5 0 0]; v3_correct = [6 0 0 0]; assert(isequal(vmultiply(v1,v2),v3_correct)) assert(isequal(vmultiply(v2,v1),v3_correct))

v1 = '1 2'

Output argument "v3" (and maybe others) not assigned during call to "vmultiply". Error in Test2 (line 4) assert(isequal(vmultiply(v1,v2),v3_correct))

3   Fail
v1 = [9 9]; v2 = [9 9]; v3_correct = [9 8 0 1]; assert(isequal(vmultiply(v1,v2),v3_correct)) assert(isequal(vmultiply(v2,v1),v3_correct))

v1 = '9 9'

Output argument "v3" (and maybe others) not assigned during call to "vmultiply". Error in Test3 (line 4) assert(isequal(vmultiply(v1,v2),v3_correct))

4   Fail
v1 = [8 3 4 5 7 1 6 9 4 0 2 0 2 1 5 8 9 4]; v2 = [1 0 0 6 6 9 4 3 1 8 2 7 0 5 4 5 5]; v3_correct = [8 4 0 1 5 8 5 8 2 5 5 9 5 7 5 5 3 3 8 6 7 6 3 6 6 1 1 1 5 0 1 7 7 0]; assert(isequal(vmultiply(v1,v2),v3_correct)) assert(isequal(vmultiply(v2,v1),v3_correct))

v1 = '8 3 4 5 7 1 6 9 4 0 2 0 2 1 5 8 9 4'

Output argument "v3" (and maybe others) not assigned during call to "vmultiply". Error in Test4 (line 4) assert(isequal(vmultiply(v1,v2),v3_correct))
