How to merge matrices generated from a for loop into one matrix.

k = 4:.05:6.90
ElementNum = numel(k)
results = zeros(3,numel(k))
for w = 1:numel(k)
    A(1,1) = k(w)
    solution = rref(A)
    solutionV = solution(:,4)  
end

The above code is what I have written. I am trying to merge all the solutionV matrices into one matrix. How do I do this?

E.g., as a matrix of columns:

solutionV = zeros(___,numel(k));  % <-- fill this in to pre-allocate
    :
  solutionV(:,w) = solution(:,4);

[patrick brannan]

That code generates a 3x59 matrix of zeros, with only the last column resembling the solutionV matrix. I'm looking to store the previous 58 matrices of solutionV in the same matrix.

That last line was supposed to be obvious that it was inside the loop. E.g.,

k = 4:.05:6.90
ElementNum = numel(k)
results = zeros(3,numel(k))
solutionV = zeros(3,numel(k));  % <-- Pre-allocate
for w = 1:numel(k)
    A(1,1) = k(w)
    solution = rref(A)
    solutionV(:,w) = solution(:,4); % <-- save as w'th column
end
