I get an error, what's wrong?

parfor m = 1:blocks
    for i = 1:nest 
        g(m,i,1) = normrnd(c(i),d(i))
        a(m,i,2) = normrnd(g(m,i,1),d(i));
        for n=2:draws;
               a(m,i,n)=normrnd(a(m,i,n-1),d(i));
        end
    end
end

.

Error using parfor_exercise (line 13)
Error: The variable g in a parfor cannot be classified.

[per isakson]

Which line is line 13?

[Ina Hajdini]

It's where the parfor begins.

parfor m = 1:blocks
    gm = zeros(1, nest);
    for i = 1:nest 
        gm(1,i) = normrnd(c(i), d(i))
        a(m,i,2) = normrnd(gm(1,i), d(i));
        for n=2:draws;
               a(m,i,n)=normrnd(a(m,i,n-1),d(i));
        end
    end
    g(m, :, 1) = gm;
end

It's giving me the following error:

Error: The variable a in a parfor cannot be classified.

[Walter Roberson]

g = zeros(blocks, nest, SomeSize);
a = zeros(blocks, nest, draws);
parfor m = 1:blocks
    gm = zeros(1, nest);
    am = zeros(1, nest, draws);
    for i = 1:nest 
        gm(1,i) = normrnd( c(i), d(i) )
        am(1, i, 2) = normrnd( gm(1,i), d(i) );
        for n=2:draws;
          am(1,i,n) = normrnd( am(1,i,n-1), d(i) );
        end
    end
    g(m, :, 1) = gm;
    a(m, :, :) = am;
end

This works. Thanks a lot!
