对一段话中的英文文字和句子计数，GUI界面源程序(count the number of all the words and sentences)

病态系统求解，解析解，以及rk-4，吉尔法等等(ill defined system)

this is an PFC demo file2.

基于Taubin论文方法的最小二乘圆拟合法 (Circle fit by Taubin G. Taubin, "Estimation Of Planar Curves, Surfaces And Nonplanar Space Curves Defined By Implicit Equations, With Applications To Edge And Range Image Segmentation",IEEE Trans. PAMI, Vol. 13, pages 1115-1138, (1991))

说明：  用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

用脉冲响应不变设计巴特沃斯数字低通滤波器(Designed by the same impulse response digital low-pass filter Butterworth)

说明：  利用matlab处理数据.采用FFT和小波分析的方法分析信号的功率谱.........(perform on the picture using matlab to analysis the power spectrum...)

这是一个matlab的源程序，只要打开就知道了，具体我久不说了谢谢大家！(This is a matlab source, as long as the Open will know the specific久不I said thank you!)

简单实用的matlab源码，描述了Q学习的过程，实现了探索和最优化.适用于初学者(Simple and practical matlab source, describing the Q learning process, to achieve the exploration and optimization suitable for beginners)

是关于GPR正演模拟的FDTD-3D算法，加载完全匹配层吸收条件。。(It is the FDTD-3D algorithm for GPR forward modeling, loading the perfectly matched layer absorbing condition.)
