¿Cómo implementar el ajuste polinomial de Chebyshev en matlab? Se requiere código fuente.
Utilice polinomios de Chebyshev para aproximar funciones conocidas
Función f = Chebyshev(y,k,x0)
syms t;
T(1:k+ 1) = t;
T(1) = 1;
T(2) = t;
c(1:k+1) = 0.0
p>
c(1)=int(subs(y,findsym(sym(y)),sym('t'))*T(1)/sqrt(1-t^2),t,-1 ,1)/pi;
c(2)=2*int(subs(y,findsym(sym(y)),sym('t'))*T( 2)/ sqrt(1 -t^2),t,-1,1)/pi;
f = c(1)+c(2)*t
para i= 3: k; +1
T(i) = 2*t*T(i-1)-T(i-2);
c(i) = 2*int (subs( y,findsym(sym (y)),sym('t'))*T(i)/sqrt(1-t^2),t,-1,1)/2;
f = f + c(i)*T(i);
f = vpa(f,6);
if(i==k+1)
if(nargin == 3)
f = subs(f,'t',x0);
else
f = vpa (f, 6);
