legender polynomial root
4.0
the zip file legender contains 10 functions.each of it has its own work.The discription how to use is stated inside program as acomment.eg epolym() function can calculate Legendre polynomials of degree up to n, i.e., 0,1, ...,n % y=lepolym(n,x) returns the Legendre polynomials % The degree should be a nonnegative integer % The argument x is a vector be on the closed interval [-1,1]; % [dy,y]=lepolym(n,x) also returns the values of 1st-order % derivatives of the Legendre polynomials upto n stored in dy % Note: y (and likewise for dy) saves L_0(x), L_1(x), ...., L_n(x) by rows % i.e., L_k(x) is the (k+1)th row of the matrix y (or dy) % Last modified on August 30, 2011
