How to force MATLAb to use 32bit floating-point numbers in a script?

49 views (last 30 days)
Is it possible to use 32bit precision thru a script or part of the script without editing the whole code?

No. You cannot simply tell MATLAB to change precision from outside the code.

On top of which, you can't define a default precision for a script within a script or function file; you can only cast to a given precision on assignment and then ensure all variables in all related calculations are also of same class or follow other strict rules to avoid results being default doubles.

Doesn't it only control the rounding mode? I couldn't demonstrate to my satisfaction that it actually did anything discernible in R2016b here; seems like in times gone by one could see the effect but I've forgotten the details of how/what did those many years ago...
I'm presuming the OP wants to actually have everything only take up single precision in memory as well???
