Problem for doing Monte Carlo Integration

Hi all, I have a problem for doing the monte carlo integration.

Below here are all the codes, the %% Monte Carlo is the section for monte carlo integration:

%% Monte Carlo
monte_carlo=0; % Initialize Input
for i=1:h 
    monte_carlo=c*(sum(y)/h(i));
end
toc % Time Execution Stop
hold on

The outputs is looks something like this

I would be grateful that someone can help me to solve this matter. Thanks :)

Your y in the ocde is a anonymous function:

  function_handle with value:

    @(x)sin(x)

You need to input some value into it....Like

y(1), y(2), y(pi) etc...

You cannot use sum(y) straight away.

May be you have to repalce this line:

     monte_carlo=c*(sum(y)/h(i));

with

    monte_carlo=c*(sum(y(x(1:i)))/h);

Thanks for helping, now I can get the answer that I want already.

But you need to improve the code. If h = 1, it will throw error.

Thanks is accepting/ voting the answer. :)
