一种算术编码器，可以快速实现压缩，在matlab中具体命令如：!ArithCoder -e -t bits Idata.dat enIdata.dat 其中Idata.dat 为需要压缩的，enIdata.dat 为编码后的-An arithmetic encoder, can quickly achieve compression, in the MATLAB specific commands such as:!-e-t bits Idata.dat ArithCoder enIdata.dat where Idata.dat for the need to compress, enIdata.dat for the encoding
