MATLAB对LED光源扩展,改变原来的光源发光强度分布(Extension of LED light source by matlab,Change the light intensity distribution of the original light source)

Pyramid.zip包含 1、pyramid.fig界面 2、高斯金字塔通过GPReduce.m函数实现 拉普拉斯金字塔由GPExpand.m函数实现 3、用imshow()显示拉普拉斯金字塔时，如果图像矩阵数据类型为double，会显示为彩色；而通过uint8()将类型强制转换为8位无符号整数，图像显示就为黑白了。 4、采用256*256的lena彩色图像(Pyramid.zip coantain 1、pyramid.fig interface 2、implemented by GPReduce.m and GPExpand.m 3、use 256*256 lena color picture)

Solution Manual for Chen Linear System Theory

非常详细的MUSIC谱估计程序，自己写的，毕业设计，保证结果正确且可以运行。有非常详细的注释，每句话都有注解，简明易懂，保证可以看懂并学到知识，并且每一步与MUSIC算法详细的对应和算法解释，不管是学习程序还是学习算法都很有帮助，.m文件中是程序的一部分，全部代码在WORD中，肯定是你见过的最好的代码(MUSIC spectrum estimation very detailed procedures for their own writing, graduation, there are very detailed notes, every word has a comment, simple to understand, to ensure you can read and acquire knowledge, and every step of the MUSIC algorithm and the corresponding detailed and algorithm explanation, whether the learning process or learning algorithms are very helpful)
