X (10000,10000) = 0; This works, but leaves me with a large array of zeroes. This has the effect of requiring twice as much memory as needed, one chunk for the preallocated zeros and one chunk for the return value of fetchAllData. If you know what is stored in each column, create the variables and add the rows as you go. There wouldn't be much point preallocating the scalar structures inside each cell, particularly if you did it naively using repmat as they would be shared copy which would need deduplicating at each step of the loop. You do not need to pre-allocate A_sub or A_sub_sub in those conditions, as you would be writing over all of them. matrix. If that happens, you get an OOME. for and while loops that incrementally increase the size of a data structure each time through the loop can adversely affect performance and memory use. The down side is that you have to manage your own memory which means you have to figure out where to put your objects which. 100 - 150 Mods = 7GB. May 13, 2015 at 12:01.
