FISTA block sparse 压缩感知加速恢复算法(FISTA block sparse)

线性方程组的Gauss_Seidel算法求解(Linear Equations Gauss_Seidel algorithm)

This function produces an image of a 3D object defined by matrix a(l,m,n) in terms of voxels the image is a view after rotating the object by angles alfa and beta (in degree) b is the image and d is its ditance to the viewer matrix The first figure depicts the object using only its gray level values The second image depicts the object using some lighting effect rotate3d may be used for reorientation but the obtained image is planner

Wideband beamforming technique which is used for voice and speech

A Comparative Study for Orthogonal Subspace Projection and Constrained Energy Minimization

好用的随机森林回归（RFR），也可用与分类。基于以编译的mex84，可实现bias-correction。回归预测精度较高(applicable random forrest regression，can also be used for classification。Regress with bias-correction 。can achieve high accuracy)

说明：  递推的极大似然法辨识程序 用递推的极大似然法对系统辨识的参数集 (recurrence of maximum likelihood method recursive identification procedures used by maximum likelihood method of system identification parameter sets)

Designs a linear phase FIR lowpass filter such that it: - minimizes maximum stopband attenuation - has a constraint on the maximum passband ripple This is a convex problem (when sampled it can be represented as an LP). minimize max |H(w)| for w in the stopband s.t. 1/delta <= |H(w)| <= delta for w in the passband ( where H is the frequency response function and variable is h (the filter impulse response). delta is allowed passband ripple. )
