在 MATLAB Online 中打开

doc InputParser

may also be of use depending what context you heard of parse input. I have never used InputParser myself though I've always wanted to try it. I hate functions that take varargin as their arguments so I don't write them so have never really needed InputParser. validateattributes always does the job for me with named function arguments.

Anyway, InputParser allows you to state what is expected in the rather unhelpfully named varargin array.

varagin, nothing. varargin (with an r) means any number of arguments. See

doc varargin

parseinput is not a standard function of matlab but in used in plenty of mathworks function to validate and parse the inputs, as the name indicates. It is always a private function of the file where it's used, so you can't call it yourself anyway.
