MATLAB Usage

File Name: multiplexor_v2_fract32_module.m

Code Block
 M = multiplexor_v2_fract32_module(NAME, ISCONTROL, NUMINPINS)
 Creates a multiplexor module that seamlessly switches between inputs.
 The module has multiple input pins and switches from one input to another.
 The optional control pin is the first pin (when enabled) and determines
 which of N inputs is selected. The input pin is an integer value in the
 range 0 to N-1.
 Arguments:
    NAME - name of the module.
    ISCONTROL - enables or disables the control pin
    NUMINPINS - number of input pins.
 All input pins must have the same block size and number of channels.
 Note, this verson implements an optional smooth crossfade between inputs.
