求多信道前向线性预测的最小二乘解法！

[hefa_zhang]

各位高手，我是做FICA的，前两天看了篇文章上说的在进行ＳＴＦＩＣＡ时必须预白化，要求的方法是多信道前向线性预测的最小二乘解法出系数做预白化（The coefficients for the jth row of the transfer function matrices are calculated by solving a least-squares multichannel forward linear prediction task, e.g.,by minimizing the output power of the th output signal.），这一方法怎么用MATLAB编程啊，想了好长时间没头绪，请各位高手指点，谢谢！
