array exceeds maximum array size preference (when summing)

I'm running a simulation that outputs a very long vector (of length 4 by 599901 -- only taking the fourth row).

I want to keep producing simulations of this length and add it to the previous result:

storage(kk,kkk,:) = soln(4,:) + storage(kk,kkk,:);

However I'm recieving the following error:

Requested 1x599901x599901 (2681.3GB) array exceeds maximum array size preference. Creation of arrays
greater than this limit may take a long time and cause MATLAB to become unresponsive.

I can complete the simulation and plot it, but I can't sum it in the way I've described? I think I'm bungling something. Can anyone help?

Use squeeze around the two terms you want to sum. The dimensions are different, so your current code attempts to use dynamic expansion, which would result in a huge matrix.

Maybe I should say kk and kkk are fixed by a loop.

Neither of the following worked:

storage(kk,kkk,:) = squeeze(soln(4,:))+squeeze(storage(kk,kkk,:));
storage(kk,kkk,:) = squeeze(soln(4,:)+storage(kk,kkk,:));

Other ideas?

Yes: put squeeze around both terms:

storage(kk,kkk,:) = squeeze(soln(4,:)) + squeeze(storage(kk,kkk,:));
