Error regarding matrix indices while iterating through loop

v = [10 20 40 60 80 100];
N = 10:5:100;
for j=1:length(v)
    pb(j) = (1/2)*(erf(((s-d)/v(j) - mu_t)/(sqrt(2)*sigma_t)) - erf(((r-d)/v(j) - mu_t)/(sqrt(2)*sigma_t)));      
    for i=1:length(N)
        qm(i,j) = qfunc((K - N(i)*PM)/sqrt(N(i)*PM*(1 - PM)))*pb(j);
    end    
end

Having this error

Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

I tried reporducing this on my end. It seems to have worked fine when I have assumed the values of some variables as shown below. With these assumptions, the code worked. Although, please check the values for the qfunc as it takes only real valued inputs. You can find more info on qfunc here.

v = [10 20 40 60 80 100];
N = 10:5:100;
s=5;
d=2;
mu_t=1;
sigma_t=2;
r=3;
K=4;
PM=0.7;
for j=1:length(v)
    pb(j) = (1/2)*(erf(((s-d)/v(j) - mu_t)/(sqrt(2)*sigma_t)) - erf(((r-d)/v(j) - mu_t)/(sqrt(2)*sigma_t)))      
    for i=1:length(N)
        qm(i,j) = qfunc((K - N(i)*PM)/sqrt(N(i)*PM*(1 - PM)))*pb(j)
    end    
end
