CHECKRAM estimate if RAM will fit a new array
checks that requested memory for the new array won't exceed AVAILABLE RAM with Matlab
Contents
Inputs
- newSize: vector of array per-dimension lengths
- myclass: name of class
Outputs
- OK: logical if array is predicted to fit in RAM
- newSizeBytes: estimated array memory usage
- freebytes: current free RAM (before allocating array)
This script is optimistic as Matlab won't always be able to create an array using ALL available RAM, but at least you know when you certainly CAN'T create an array without digging deep into swap or worse.
