Amend a column vector to a matrix array

1 view (last 30 days)
What are some simple ways to amend a column vector to an array? I am trying to avoid setting a fixed number of column vectors to an array and would rather amend column vector after column vector with a while loop until it reaches the end of the loop. Feel it would be unnecessary to fix the length of the array if this could happen and it would be more fluid

hugh, well i'll take the increase in round off error if it provides a better matrix that fits my data set more accurately

No, it won't be more fluid, because of
A compromise would be to hold the columns in a cell array and then combine them at the end, e.g.,
i=1;
c={};
while i<10
c{i}=rand(4,1);
i=i+1;
end
A=cell2mat(c)
A = 4×9
