Answer 1

Hi,

a bit old but still valid I think:

And also more or less valid:

Since out = rand(10^9,4) gives an out of memory on 64bit but out = rand(10^9,3) works.

And you can run

[str,maxsize] = computer

in order to figure out the maximum number of elements allowed in an array with this version of MATLAB. See doc under
