osx - Matlab call to CPLEX seems to use A LOT of memory -


i have matlab function creates linear program , calls cplex solve it. right before call cplex.solve, total size of variables in workspace no more 200mb. however, when run function problems of moderate size, can see in activity monitor (i have mac) available memory drops 9gb down 0; returns around 8gb while cplex solving problem. large problem sizes, available memory goes 0, , starts swapping memory, unacceptable performance use-case.

so seems there memory usage spike right matlab calls cplex. wondering if else out there has had problem , if there can done it.

for reference, have imac 3.2 ghz intel core i5 , 16 gb 1600 mhz ddr3 memory. running os x 10.8.3, matlab r2013a, , cplex 12.5.

thanks in advance help. please feel free ask clarifications.
