Syntax

tf = isfixed(a)
tf = isfixed(T)
tf = isfixed(q)

Description

example

tf = isfixed(a) returns 1 (true) when the DataType property of fi object a is Fixed. Otherwise, it returns 0 (false).

example

tf = isfixed(T) returns 1 when the DataType property of numerictype object T is Fixed. Otherwise, it returns 0 (false).

example

tf = isfixed(q) returns 1 when q is a fixed-point quantizer object. Otherwise, it returns 0 (false).
