When I run my function I want a row vector not a column

I have a simple function that generates large numbers. The ans is a column vector but I want a row. ans' changes it to what I want but I need it to run in the function. I'm not sure how to do that?

upload your function first

One simple solution is to use subscript indexing (but this will be quite inefficient):

function n = num(k)
n(1,1) = 1;
n(2,1) = 1;
k = 3;
while k<=100
    n(k,1) = n(k-1)+n(k-2);
    k = k+1;
end

The best solution is to preallocate the output array (much more efficient):

function n = num(k)
n = ones(100,1); % preallocate
k = 3;
while k<=numel(n)
    n(k) = n(k-1)+n(k-2);
    k = k+1;
end

Here's what I have:

function [n] = num(k)
n(1)=1;
n(2)=1;
k = 3;
while k <=100
   n(k) = n(k-1)+n(k-2);
  k= (k+1);
end

The answer is a 1x100 double. (they probably look familiar) I need a 100x1 matrix.

Yes, that's exactly it! Thank you for the help everyone.

eta: I'll use "zeros" and leave it defined as it is, but it's the allocation that really helped. Thanks, it was driving me mental.
