# convenc

Convolutionally encode binary message

## Syntax

## Description

encodes the input binary message by using a convolutional encoder represented by a
trellis structure. For details about trellis structures in MATLAB`codedout`

= convenc(`msg`

,`trellis`

)^{®}, see Trellis Description of a Convolutional Code. The input message contains one or more symbols, each of which consists of log2(`trellis`

.`numInputSymbols`

) bits. The coded output, `codedout`

, contains
one or more symbols, each of which consists of log2(`trellis`

.`numOutputSymbols`

) bits.
