k_medoids
聚类算法:k—medoids 方法。这儿选取一个对象叫做mediod来代替上面的中心 的作用,这样的一个medoid就标识了这个类。步骤: 1,任意选取K个对象作为medoids(O1,O2,…Oi…Ok)。 以下是循环的: 2,将余下的对象分到各个类中去(根据与medoid最相近的原则); 3,对于每个类(Oi)中,顺序选取一个Or,计算用Or代替Oi后的消耗—E(Or)。选择E最小的那个Or来代替Oi。这样K个medoids就改变了,下面就再转到2。 4,这样循环直到K个medoids固定下来。 这种算法对于脏数据和异常数据不敏感,但计算量显然要比K均值要大,一般只适合小数据量。 这里是MAtlab源代码。(err)

quantization_sim
说明: 利用Matlab及Simulink建立仿真系统,对PCM量化信噪比进行仿真测试,要求对输入的正弦波进行采样、量化和PCM编码,计算并画出量化信噪比曲线,比较量化信噪比理论值与实际值。(Using MATLAB and Simulink to set up simulation system to simulate and test the quantized signal-to-noise ratio of PCM, it is required to sample, quantize and PCM code the input sine wave, calculate and draw the quantized signal-to-noise ratio curve, and compare the theoretical value and the actual value of the quantized signal-to-noise ratio.)

dls3D
the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolution
spectral estimation of target reflectivity.
all seven (7)files should be downloaded for the simulation to work.
