a = sint(TotalBits)
sint(TotalBits) returns a MATLAB structure that describes the data type of a signed integer with a word size given by TotalBits.
sint is automatically called when a signed integer is specified in a block dialog box.
The default binary point for this data type is assumed to lie to the right of all bits.
Define a 16-bit signed integer data type:
a = sint(16)
a =
Class: 'INT'
IsSigned: 1
MantBits: 16
fixdt, float, sfix, sfrac, ufix, ufrac, uint
