说明：  hdr格式高光谱图像matlab读取与显示，含数据集(Matlab reading and display of hyperspectral image in HDR format, including data set)

最后的测试程序，得出文本检索的正确率和召回率(In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over the classic LSA retrieval algorithm in precision and operational efficiency.)

低通滤波器，用Matlab编程实现低通滤波器的功能(Low-pass filter, using Matlab programming function of the low-pass filter)

小波变换的matlab源程序，有两个版本，这是第二板。(wavelet transform Matlab source, there are two versions, which is the second plate.)

正弦波脉宽调制技术（SPWM）三相正弦调制波与双极性三角载波设计与实现(Sinusoidal pulse width modulation (SPWM) three-phase sinusoidal modulation wave bipolar triangular carrier Design and Implementation)

基于小波变换的分开—合并图像分割matlab．采用多尺度小波变换系数作为四分树结构的分开一合并法图像分割的一致性度量 从而在大的图像块中。。去除噪声的影响，在小的图像块中，以小波变换的局部极大值精确定位边缘，根据边缘信息进行分开一合并法图像分割 ．实验表明．算法得到满意的结果 ． (Separately based on wavelet transform- merge image segmentation Matlab. Multi-scale wavelet transform coefficients as the quadtree structure separate consolidation method of image segmentation consistency measure large image block. . To remove the effects of noise, in small image blocks, the local maxima of the wavelet transform precise positioning edge, to separate a combined method for image segmentation according to the edge information. Experiments show. Algorithm to obtain satisfactory results.)
