Hello I am trying to write a function file that will take a row vector representing a polynomial and return a 0 if it at least one of the coefficents of the polynomail is zero and a 1 if otherwise.

Many thanks in advance.

在 MATLAB Online 中打开

function flg = isFullPoly(b)
% isFullPoly(b) returns T if all  coefficients, b, nonzero, F otherwise
  flg=all(b);
end

This one really doesn't need a function for other than "syntactic sugar" to indicate what are testing which a comment could do as well...but, nothing really wrong with doing so if wish...
