polyval是个什么函数呀<br /><br />y = polyval(p,x) returns the value of a polynomial of degree n evaluated at x. 返回的是一个n阶多项式阶付给x的值?????<br /><br />The input argument p is a vector of length n+1 whose elements are the coefficients in descending powers of the polynomial to be evaluated.<br /><br />一个多项式p = s^2 ,另一个为x = 1,polyval(p,x)是什么呢? |
