Below you will find complete listings of a MATLAB function M-file, and a test script for that M-file, except that at a few places in the files code has been removed.

Before the code was removed, the MATLAB function correctly returned a logical value (true or false) depending on whether the first parameter x, appears in a row vector represented by the second parameter, v. If v is empty, the function returns false.

You may assume that the function performEqualTest operates correctly.

Fill in the missing code.
