Ldexp

Overview

Computes the function y = ldexp(f,e) using the math library

Discussion

Computes the function Y = ldexp(F, E) using the math library. The function computes a floating point number starting with a fractional value F and an exponent E as: Y = F * 2^E. This function is the inverse of frexp().

MATLAB Usage

File Name: ldexp_module.m

 M=ldexp_module(NAME)
 Creates an Audio Weaver module that computes the function ldexp(F, E)
 using the math library.  This function computes a floating point number
 starting with a fractional value F and an exponent E as:
    Y = F * 2^E
 The function is the inverse of the function frexp().  Arguments:
    NAME - name of the module.
