Hello,

I need to know how to do few things in Matlab. It would be easier to show you the whole code, i need to do what is written in the lines that start by % (except for %dW, for the moment at least).

Here is the code i'm working on:

N = 10;

t = 1:N;

d = 3;

R = 2*pi*rand(6);

for i = 1:6

for j = 1:6

W(i,j) = 6*(i-1) + j;

nc = %integer of W(i,j) + 2

%dW = differences in W

    for dt = 1:length(t);
        g(etha) = exp(-(etha^2) / (2*dt)) / (2*pi*dt)^(d/2);
        R = R + etha * sqrt(2*1/2*dt);
        W = W * exp(-dW * dt);
    end
    if W(i,j) > 1 && nc >= 2
       % create nc copies of R(i,j) of which W = W-1
    elseif W(i,j) < 1
        % delete R(i,j) of which W = 1-W
    end
    end

end

In addition, g(etha) is supposed to be a probability density, and the etha that goes out from it is this i have to insert in R (the line after g(etha)). Does anybody know how i have to set this?

Thank you very much,
