making a 341x341 matrix from a 465124x1 matrix.

Hello everybody,

I have a matrix that is 465124x1. From this matrix I want every 341 values put in another matrix. so the values from 1-341 is the first column and than the values from 342-683 is the second column etc. This should yield a 341x341 matrix.

It gives a 341x341 matrix but just with the values from 1-341 from the orginal matrix. Here is my code:

for i = 1:341:465124
      for p = 1:1:341 
          a = i+340;
          kolom(:,p) = value(i:a,1);
      end
end

I do not know what i am doing wrong so please help.

Thank you!

But 341*341 gives 116281, not 465124 ...?

Titus, this is a surprising detail.

Sounds like you are looking for the RESHAPE command.

[Jeroen]

okay thank you I tried the reshape function and it works now

465124/(341*341)=4

You will get 4 341*341 matrices from one 465124 matrix..

You could try

% a is your 465214x1 matrix

b=reshape(a,341,341,[])   % this will give u a 3 dimensional matrix of size (341*341*4)
