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);
tf = isfi(a)

tf = logical
   1

b = single([1 2 3 4]);
tf = isfi(b)

tf = logical
   0

Input Arguments

a — Input array

array

Input array.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

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.

HDL Code Generation
Generate VHDL, Verilog and SystemVerilog code for FPGA and ASIC designs using HDL Coder™.
