I have the following 1x10 matlab structure where all 10 elements are column vectors of varying length. I want to populate the first 10 row of a matrix of zeros of size 256x160 with this structure such that first 10 rows of the matrix are replaced by 10 column vectors values respectively. If length does not cover all 160 values it will stay 0 as before. Could you kindly help? Thank you so much.

If S is your struct array and M is your matrix of zeros:
for ii = 1:numel(S)
M(ii,1:numel(S(ii).times)) = S(ii).times;
end

Hi Voss, it works. Thank you so much. By the way, you have any idea how can I do the same task without having the initial matrix of zeros defined. Actually I'm planning to keep the structure values only in my outcome matrix and no zeros.
