sfix - Create MATLAB structure describing signed generalized fixed-point data type

Syntax

a = sfix(TotalBits)

Description

sfix(TotalBits) returns a MATLAB structure that describes the data type of a signed generalized fixed-point number with a word size given by TotalBits.

sfix is automatically called when a signed generalized fixed-point data type is specified in a block dialog box.

Note   A default binary point is not included in this data type description. Instead, the scaling must be explicitly defined in the block dialog box.

Examples

Define a 16-bit signed generalized fixed-point data type:

a = sfix(16)
a = 
       Class: 'FIX'
    IsSigned: 1
    MantBits: 16
