Read vectors into a matrix of NaNs??

I have a large 25x25 matrix full of "NaN". I created it so that I could put several different 1-dimensional arrays of different lengths into one matrix together. But now I am having issues replacing the NaNs with the elements of the individual arrays.

For example, I have the big matrix "SalMat"

SalMat = repmat({NaN},25,25);

And I would like for sal01 to be the new first column of SalMat:

sal01 =

   26.7762
   26.7769
   26.7773
   26.7781
   26.8047
   27.0839
   28.6000
   30.5953
   32.4578
   33.2129
   34.0983
   34.4630
   34.6466
   34.6961
   34.7120
   34.7924
   35.4376
   35.5727

This would then be repeated with sal02,sal03,....sal25 inserted into the 25 columns of SalMat.

Any suggestions???

repmat({nan},blah)

will replicate a cell of nan. You don't want cells ( doc cell, for more info). You want a regular matrix:

Salmat = nan(25); %same as repmat(nan,25,25);

Then do the insertions. Also read this FAQ4.6

Thank you!

SalMat = nan(25)
c  = arrayfun(@(x)randi(randi(123),randi(25),1),1:25,'un',0)
for j1 = 1:size(SalMat,2)
   SalMat(1:numel(c{j1}),j1) = c{j1};
end
