compensate vector into same length
显示 更早的评论
if we have multiple vectors, A,B,C. Each of them has different length. How can we compensate them by NaN into same length and store them as a matrix.

The simplest approach is to download the function PADCAT() here:
and use it like this:
M = padcat(A,B,C)

"For example, I have a loop for 4 times, within each loop I will get a vector, then I need to compensate the vector with NaN within that loop; then in next loop I will have new vector to compensate."
How will you know what length to pad to, if you do not have all of the vectors?
I suspect that you could simply store all of the vectors in a cell array, and then supply them to PADCAT after the loop. This would likely be the simplest approach:
N = 4;
C = cell(1,N); % preallocate!
for k = 1:N
V = your code that generates a vector;
C{k} = V;
end
M = padcat(C{:})
