Hi everybody,

I have an error with my code when i create a matrix in matlab. Can you see it and help me!

-----------------------------------------

lamda=0.2;M=5;T=50;
for i=1:M
    for j=1:M
        if i==j B(i,j)=exp(-lamda*T);
        elseif i>j B(i,j)=0;
        else B(i,j)=exp(-lamda*T)*(lamda*T)^(j-i)/factorial(j-i);
        end     
    end
end
K=zeros(1,M)
A=[B;K]

-------------------------------------------

If i run program in fisrt time ---> ok. No when i change value of "M=5" to another value and run again, it will be appear error:

Error using vertcat

Dimensions of arrays being concatenated are not consistent.

Error in VD (line 14)

B=[A;K]z

----------------------------------

When I restart again Matlab, it will be ok at the first time and then error will be repeat. Please help me. If you have a good ideal and show me how to creat this metrix, i will be so very happy.

Thanks so much!
