Circular Array Beam Patterns

是关于vblast的检测算法研究的分析，主要是算法和性能比较(On vblast detection algorithm analysis, algorithm and the performance is mainly)

Bloch simulator. [mx,my,mz] = bloch(b1,gr,tp,t1,t2,df,dp,mode,mx,my,mz) Bloch simulation of rotations due to B1, gradient and off-resonance, including relaxation effects. At each time point, the rotation matrix and decay matrix are calculated. Simulation can simulate the steady-state if the sequence is applied repeatedly, or the magnetization starting at m0. INPUT: b1 = (Mx1) RF pulse in G. Can be complex. gr = (Mx1,2,or 3) 1,2 or 3-dimensional gradient in G/cm. tp = (Mx1) time duration of each b1 and gr point, in seconds, or 1x1 time step if constant for all points

说明：  用matlab的simulink做的对选择式分集进行的测试 及性能验证。(Using matlab to do the simulink of Selective sub-set of testing and performance validation.)

this file contains the heatcool system model. you can use these models in simulink environment. For model analyisis matlab is required

matlab 有限元程序代码,能够供大家学习参考 (matlab finite element program code, good enough for them to learn information)

这是一个已知ar模型参数求功率谱密度的函数(Ar model parameters are known to seek the power spectral density function)

说明：  时间混叠信号matlab程序,是利用时间混叠信号进行循环谱估计的前提。该程序用于证明时间混叠后信号为周期信号。(Time Aliasing)

here is fantastic iso clustering code which i test it frequently and find it satisfactory. it does k maen clustering in two dimensional data.
