一个用matlab写的特征挑选，大家试试吧！(Using matlab to write a feature of the selection, we give it a try!)

关于拟合的程序，对学习信号处理的同学们很有帮助，做曲线拟合时很有用(On the fitting procedures, students learn useful signal processing, curve fitting is useful when doing)

说明：  利用Matlab，建立了PFC电路的精确仿真模型，没有斜坡补偿。(matlab,PFC simulation)

许多关于kalman滤波实现的matlab源程序！希望对大家有所帮助(Achieve many of kalman filter matlab source! We want to help)

matlab 编写的惯导定位程序，可以直接运行(INS positioning written in matlab program can be run directly)

萤火虫算法实现求解最优问题，测试函数表明取得较好效果(Solving the Optimal Problem by Firefly Algorithms)

matlab code generation

this example finds the gapes that are existed in a word

说明：  算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 (Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.)
