Unconstrained optimization of single variable

说明：  從三角求和公式到Fourier 級數,推导很详细(From the Triangle to the Fourier series summation formula, derived in great detail)

三维重构技术，里面有详细的介绍。其开发环境matlab(Three-dimensional reconstruction technique, which has a detailed introduction. Their development environment matlab)

实现彩色作图，可实现不同frame累计，并进行插值(Color mapping can be accumulated to achieve a different frame, and interpolation)

说明：  冈萨雷斯的图像处理MATLAB版的函数集，加到MATLAB路径中后就可以使用这些函数了(the functions of the digital image processing in matlab )

调试通过可以使用，包括主成分分析、因子分析、贝叶斯分析，用MATLAB实现动态聚类或迭代自组织数据分析，旋转机械二维全息谱计算，具有丰富的参数选项,包含了阵列信号处理的常见算法，欢迎大家下载学习。 ( Debugging can be used, Including principal component analysis, factor analysis, Bayesian analysis, Using MATLAB dynamic clustering or iterative self-organizing data analysis, Rotating machinery 2-d holographic spectrum calculation, It has a wealth of parameter options, Contains a common array signal processing algorithm, Welcome to download the study. )

Sullivan Dennis的electromagnetic simulation using fdtd method一书中代码MATLAB版(Sullivan Dennis--electromagnetic simulation using fdtd method MATLAB)

灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。(Gray theory that the behavior of the system even though the phenomenon is dim, the data is complex, but still it is ordered, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. Meanwhile, the gray theory is to generate the data model, not the original data model, so gray prediction data by generating data gm (1,1) model predicted values ​ ​ obtained result of the inverse process.)

用matlab实现的主元分析算法，很实用的程序，经调试通过(Matlab principal component analysis algorithm, very practical program, the debugging through)

This is a DoA estimation algorithm named BARTLETT.
