Adding entry to a matrix loop
显示 更早的评论
I have a matix, A, of 100x200 zeros. I will be taking data from an oscilloscope that will continually be written to a matrix, B, 1X1. I want to write a loop that inputs B into the spot 1,1 of A. Then after the oscilloscope has taken new data and rewritten B, input it into spot 1,2. When the first line is complete I want the data to go into 2,1 and so on till A is full up. How might I write this loop?

Why pray tell, do you want to write data into a matrix along those diagonals? Where does the 4th element go?

Hello,
You can fill in your matrix by rows with this:
for i = 1:100
for j = 1:200
% Acquire your B
A(i,j) = B;
end
end
Hope this helps!

Your loop goes from i=1:100 and j=1:200 correct? Not 0:100 and 0:200? This error occurs when you try to access A(0,0) which does not exist.
