Hi guys!
I have a data 4624X12 and i need transpose every line to columns, to getting a 55488X1 matrix.
I tried the following loop:
j=1; [row,col]=size(data); for i=1:row M(j)=data(i,:)'; j=j+1 end
This error appier in this situation: "??? In an assignment A(I) = B, the number of elements in B and I must be the same"
Tks every budy!

Your words "transpose every line to columns" hint that you wish the rows to remain contiguous within the single column. If so, do this:
M = data.';
M = M(:);

>> newdata = reshape(data,55488,1)

The error message explains exhaustively, why M(j)=data(i,:)' must fail: There is a vector on the left side, but a scalar on the right side. Obviously you cannot assign the values of a vector to one scalar.
Roger's answer solves the problem efficiently.
