'gf'域的矩阵怎么变，求matlab高手

我试验了一下，还是可以对a作四则运算的，不过结果好像是代数域的四则运算结果不同。我觉得可能是gf域的原因吧，可能有它们自己定义的运算。Operations supported for Galois Field arrays:
+ -
- Addition and subtraction of Galois arrays.
* / \
- Matrix multiplication and division of Galois arrays.
.* ./ .\
- Elementwise multiplication and division of Galois arrays
^
- Matrix exponentiation of Galois array.
.^
- Elementwise exponentiation of Galois array.
' .'
- Transpose of Galois array.
==, ~=
- Relational operators for Galois arrays.

a = GF(2^8) array. Primitive polynomial = D^8+D^4+D^3+D^2+1 (285 decimal)
