Hi everyone, i have a complex function which i have written a matlab function to execute, but before that i did a simple example of definite integral of the form
int_0^1 log int_0^1 x+y dxdy .(here 'int' is the integral sign, underscore 0 hat 1 are the limits of integration, done w.r.t x and y)
doing this by pen and paper gives me -1.33333… but using this code below.i get a wrong answer.
function z1=intlog(y)%intlog is a function executing the inner integral with respect to %x.
n=length(y); z=zeros(size(y));for j=1:na=0;b=1;h=@(x) (x+y(j));z(j)=quad(h,a,b);z1=log(z);end
to run this write in command window:
q=quad(@intlog,0,1)
which gives me a wrong answer. any explanation for this. I am using matlab release 2009a.
Thanks in anticipation.
