Usually, from the name, it's intended to parse the input arguments to the main function.

No you SHOULD NOT just delete it for two reasons.
1) In general, you should not modify functions that are part of MATLAB or toolboxes created by MathWorks. Doing so could easily cause them to return the wrong answer, to throw errors, or to misbehave in subtle or not-so-subtle ways. If you MUST modify functions in MATLAB or a toolbox, it would be a little safer to make a copy under a new name in a directory outside $MATLABROOT/toolbox and modify that copy.
2) Removing a subfunction from a function "just because" would be like your doctor removing one of your internal organs "just because."
