matlab code for spatiograms of images

是一本结合matlab学习数字信号处理得好书(Is a combination of digital signal matlab learning to deal with the book)

说明：  里面包含很多MATLAB时频分析的程序，很有用。通过稍微改动就可以应用到其他的地方。(matlab source program)

激光作为21世纪四大发明之一，在各个行业积极发挥着作用，这里介绍了各种常用激光器的参数和应用范围(Laser as a 21st century one of the four great inventions in various industries to actively play a role in a variety of commonly used lasers presented here the parameters and scope of application)

说明：  采用松弛因子法处理多学科协同优化问题的一个具体算例，验证了协同优化方法的有效性(Relaxation factor treatment effectiveness of multidisciplinary collaborative optimization problems, a specific example, verify the collaborative optimization method)

时域有限差分方法在一维格子中计算麦克斯韦旋度方程(the finite-difference time-domain solution of Maxwell s curl equations over a one-dimensional space lattice comprised of uniform grid cells)

说明：  matlab程序解非线性方程KVD方程，非常方便(matlab)

说明：  matlab小波变换实例，用mallat快速算法将其进行频率分割，最后将低频重组，最后去噪效果(matlab wavelet transform instance, with mallat fast algorithm to the frequency division, and finally to low-frequency reorganization, the final denoising)

采用小波阈值处理的方法对加速度计的输出数据进行处理，并比较补偿前后的效果。 (Accelerometer output data wavelet filtering process)

介绍UBM模型MAP算法过程，对于说话人识别有帮助(UBM model describes the process of MAP algorithm for speaker recognition helpful)
