Tip: Feed Simulink Type Name to numerictype
If the type name corresponds to a numeric type (not a Bus, Enum, Alias, or user custom type), then feed the string to numerictype to get a numerictype object that explains the details.
nt1 = numerictype("sfix16_Sp1_Bn25")
nt1 =
DataTypeMode: Fixed-point: slope and bias scaling
Signedness: Signed
WordLength: 16
Slope: 0.1
Bias: -25
nt2 = numerictype("ufix7_En5")
nt2 =
DataTypeMode: Fixed-point: binary point scaling
Signedness: Unsigned
WordLength: 7
FractionLength: 5
nt3 = numerictype('single')
nt3 =
DataTypeMode: Single
Tip 2: fixed.extractNumericType can also be used and is more general
fixed.extractNumericType can convert many inputs to its numerictype object. See it's help for more info.
nt4 = fixed.extractNumericType('half')
nt5 = fixed.extractNumericType("flts8_E6")
nt5 =
DataTypeMode: Scaled double: binary point scaling
Signedness: Signed
WordLength: 8
FractionLength: -6
Tip 3: fixdt also works except for scaled doubles
nt6 = fixdt('sfix123_S4_B5')
nt6 =
NumericType with properties:
DataTypeMode: 'Fixed-point: slope and bias scaling'
Signedness: 'Signed'
WordLength: 123
Slope: 4
Bias: 5
IsAlias: 0
DataScope: 'Auto'
