isfi

Determine whether variable is fi object

Syntax

tf = isfi(a)

Description

tf = isfi(a) returns 1 (true) if a is a fi object. Otherwise, it returns 0 (false).

Examples

Determine Whether Variable is a fi Object

Create a variable and determine whether it is a fi object.

a = fi(pi)

a = 
    3.1416

Usage notes and limitations:

• Avoid using the isfi function in code that you intend to convert using the automated workflow. The value returned by isfi in the fixed-point code might differ from the value returned in the original MATLAB^® algorithm. The behavior of the fixed-point code might differ from the behavior of the original algorithm.
