RNW_perm(A) 利用Ryser-NW方法，计算n*n矩阵A的积和式。计算时间随着n 以2的指数倍增长。计算20*20以内的矩阵很快。 Hperm(A) 利用双元素展开计算非常稀疏的矩阵的积和式 symmRegular(n,k,m) 该命令要调用symmGen函数。 生成对称的k-regular n阶0-1矩阵的启发式算法。 参数n,k是必须的。m的默认值是10。 m设定尝试次数，如果该命令显示 fail ,表明经过m次尝试， 没有生成满足条件的矩阵。 symmGen(n,k) 这里k是一个n维向量，该命令启发式地生成一个以k为行和 的对称0-1矩阵。不能保证每次都成功，不过成功的概率一 般情况下尚可接受。(some useful code for numerical analysis)

说明：  本程序实现了CT系统在锥形束等距投影情况下，2D图像的重建(This procedure achieved a cone-beam CT system in the case of isometric projection, 2D image reconstruction)

用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

Simulink the use of the block to refine the model

this matlab code is useful for ranging applications where localization done using maximumum likelihood algorithm.

There is some matlab program for image processing..
