Set global fimath to MATLAB factory default
resetglobalfimath
resetglobalfimath sets the global fimath
to the MATLAB® factory default in your current MATLAB session.
The MATLAB factory default has the following properties:
RoundingMethod: Nearest
OverflowAction: Saturate
ProductMode: FullPrecision
SumMode: FullPrecisionIn this example, you create your own fimath object F and
set it as the global fimath. Then, using the resetglobalfimath command,
reset the global fimath to the MATLAB factory default setting.
F = fimath('RoundingMethod','Floor','OverflowAction','Wrap');
globalfimath(F);
F1 = fimath
a = fi(pi)
F1 =
RoundingMethod: Floor
OverflowAction: Wrap
ProductMode: FullPrecision
SumMode: FullPrecision
a =
3.1416
DataTypeMode: Fixed-point: binary point scaling
Signedness: Signed
WordLength: 16
FractionLength: 13
Now, set the global fimath back to the factory default setting
using resetglobalfimath:
resetglobalfimath;
F2 = fimath
a = fi(pi)
F2 =
RoundingMethod: Nearest
OverflowAction: Saturate
ProductMode: FullPrecision
SumMode: FullPrecision
a =
3.1416
DataTypeMode: Fixed-point: binary point scaling
Signedness: Signed
WordLength: 16
FractionLength: 13
You've now set the global fimath in your current MATLAB session
back to the factory default setting. To use the factory default setting
of the global fimath in future MATLAB sessions, you must use
the removeglobalfimathpref command.
reset( —
If G)G is a handle to the global fimath, reset( is
equivalent to using the G)resetglobalfimath command.
