Hi, I would like to save a vector (size change at every loop) in a matrix

I would like to divide a vector in many vectors and put all of them in a matrix. I got this error "Subscripted assignment dimension mismatch."
STEP = zeros(50,1);
STEPS = zeros(50,length(locate));
for i = 1:(length(locate)-1)
STEP = filtered(locate(i):locate(i+1));
STEPS(:,i) = STEP;
end
I take the value of "filtered" from (1:50) at the first time for example and I would like to stock it in the first row of a matrix, then for iterations 2, I take value of "filtered from(50:70) for example and I stock it in row 2 in the matrix, and this until the end of the loop..
If someone has an idea, I don't get it! Thank you!

Vectors with different sizes cannot be stacked into a single array. You can, for instance, use cell arrays as an alternative.
C = cell(5,1) ;
for k=1:5,
C{k} = 1:k ; % vectors with different sizes on each iteration
end
