fixdt (Simulink Reference)

Create a Simulink.NumericType object describing a fixed-point or floating-point data type

Syntax

a = fixdt(Signed, WordLength)
a = fixdt(Signed, WordLength, FractionLength)
a = fixdt(Signed, WordLength, TotalSlope, Bias)
a = fixdt(Signed, WordLength, SlopeAdjustmentFactor, FixedExponent, 
Bias)
a = fixdt(DataTypeNameString)
[DataType,IsScaledDouble] = fixdt(DataTypeNameString)

Description

fixdt(Signed, WordLength) returns a Simulink.NumericType object describing a fixed-point data type with unspecified scaling. The scaling would typically be determined by another block parameter.

fixdt(Signed, WordLength, FractionLength) returns a Simulink.NumericType object describing a fixed-point data type with binary point scaling.

fixdt(Signed, WordLength, TotalSlope, Bias) or fixdt(Signed, WordLength, SlopeAdjustmentFactor, FixedExponent, Bias) returns a Simulink.NumericType object describing a fixed-point data type with slope and bias scaling.

fixdt(DataTypeNameString) returns a Simulink.NumericType object describing an integer, fixed-point, or floating-point data type specified by a data type name. The data type name can be either the name of a built-in Simulink data type or the name of a fixed-point data type that conforms to the naming convention for fixed-point names established by the Simulink Fixed Point product.

[DataType,IsScaledDouble] = fixdt(DataTypeNameString) returns a Simulink.NumericType object describing an integer, fixed-point, or floating-point data type specified by a data type name and a flag that indicates whether the specified data type name was the name of a scaled double data type.
