32 bit vs 64 bit machine effect in computing equal code

6 visualizzazioni (ultimi 30 giorni)
32bit and 64bit Windows don't compute the same result for the same code written and run with Matlab 32bit. The difference I have noted are few in a large calculus, but they are present. Shortly, my computation has not been exactly replicate with both machine. Why? How to control this machine effect?

Hi Alberto,
Some higher-level algorithms boiling down to basic arithmetic operations can result in different results, when they are performed in different environments due to the very nature of floating-point arithmetic.
