Why is a regular expression used in this code?

I found a code to dump zero rows/columns in the southeast part of a given matrix:

function b = ZeroDumping(a)
  regexp '' '(?@  b=transpose(deblank(transpose(deblank(a)))); )'
end

I do understand the part 'b=transpose(deblank(transpose(deblank(a))));', but I have no idea what the other parts are doing. Why is the regular expression used in this code? What does " '' '(?@" represent?

This syntax is designed to fool the Cody score calculator to think it is using only a few non-complex function calls.

In every other situation this is a terrible way to write code.

Oops, such an evil purpose behind this code! I won't copy this code, then.

I never would have guessed that!
