在SENSE成像中如何将中间图像转化为最终图像，就要用到这个程序(Using specfied sampling vector to generate a 2D aliasing matrix. The sampling vector is a vector of n-entries of either 0 or 1, where 0 indicates no k-space line acquisition and 1 indicates k-space line is acquired in the accelerated scan. For example, a sampling vector of [0 1 0 1 0 1 0 1 0 1] indicate the 2-fold acceleration with 8 phase encoding lines. The aliasing matrix is calculated based on Fourier imaging)

说明：  图像处理中将极坐标转换为笛卡尔左边的几个调用函数，包含bin,density 和ffgrid(in the image process,please convert the polar coordinate into castinate coordinate, there are some diaoyong functions ,include bin,density and ffgrid)

说明：  使用5阶巴特沃斯半带滤波器4通道完美重构滤波器组来处理音频数据的例子(Using the 5-order Butterworth filter with a 4-channel semi-perfect reconstruction filter banks to process audio data examples)

说明：  MATLAB通信系统随机数产生mfiles，均匀、瑞利、高斯随机数发生器(Communication systems random number generator MATLAB mfiles, uniform, Rayleigh, Gaussian random number generator)

三维时域有限差分matlab程序，带完美匹配层(Three-dimensional finite-difference time-domain matlab program, with perfectly matched layer)

Representation of a Dalvik class, which is basically a set of members (fields or methods) along with a few more pieces of information.

This code implements the Harris Corner Detector.

PUMA560A的仿真控制。很详细。非本人写的，但是写的很好(PUMA560A simulation control. Very detailed. Non-I write, but write the good)
