matlab计算过程显示
function [I,step]=Roberg(f,a,b,eps)
if(nargin==3)
eps=1.0e-4;
end;
M=1;
tol=10;
k=0;
T=zeros(1,1);
h=b-a;
T(1,1)=(h/2)*(subs(sym(f),findsym(sym(f)),a)+subs(sym(f),findsym(sym(f)),b));
while tol>eps
k=k+1;
h=h/2;
Q=0;
for i=1:M
x=a+h*(2*i-1);
Q=Q+subs(sym(f),findsym(sym(f)),x);
end
T(k+1,1)=T(k,1)/2+h*Q;
M=2*M;
for j=1:k
T(k+1,j+1)=T(k+1,j)+(T(k+1,j)-T(k,j))/(4^j-1);
end
tol=abs(T(k+1,j+1)-T(k,j));
end
I=T(k+1,k+1);
step=k;
我想显示出T表请问怎么样做
