Create Transition probability matrix

Hello,

I have X1(1:n,1) and X2(1:n,1) two datas. how can I generate matrix transition probability matrix of these two datas. can you help me?

[Walter Roberson]

What is the relationship between the two? For example does X1(K) contain a starting node number and X2(K) contains the corresponding ending node number and you want to find the statistics of starting at X1(K) and ending at X2(K) (assuming that there might be repetitions and that for any given node X1(K) the destination node X2(K) will not necessarily always be the same) ?

hello

X1(:,1)=X2(:,1) is time X1(:,2)is motor speed X2(:,2)is motor torque

Hint:

 accumarray([X1,X2],something)
