<h2>Galois Field Functions</h2>
This toolbox contains a collection of MATLAB functions for
Galois Field (GF) computation. The reason for building GF is because
block coding techniques are built on the basis of GF.
The functions includes:
<dl>
<dd><b><a run="hthelp flxor">flxor</a></b> - Exclusive OR calculation.
<dd><b><a run="hthelp gfadd">gfadd</a></b> - GF additive computation.
<dd><b><a run="hthelp gfconv">gfcon</a></b> - GF polynomial convolution (multiply) computation.
<dd><b><a run="hthelp gfcosets">gfcosets</a></b> - Cyclotomic cosets generator.
<dd><b><a run="hthelp gfdeconv">gfdeconv</a></b> - GF polynomial deconvolution (dividing) computation.
<dd><b><a run="hthelp gfdiv">gfdiv</a></b> - GF dividing computation.

<dd><b><a run="hthelp gflineq">gflineq</a></b> - Computer X in A X = B in GF(p) field.
<dd><b><a run="hthelp gfminpol">gfminpol</a></b> - Find minimal polynomials.
<dd><b><a run="hthelp gfmul">gfmul</a></b> - GF multiplicative computation.
