提供memeory的说明和支持。并提供EPLD的说明CODE(Provide memeory instructions and support. And provide a description of EPLD CODE)

图像处理，双线性滤波器MATLAB程序，经调试可用(Image processing, bilinear filter MATLAB program)

它是基于matlab的语音分帧的代码，相信对大家理解有帮助。(It is based on the matlab voice sub-frames of the code, I believe we understand help.)

This is for counting the vehicles in the night time traffic

MATLAB自己做的 好像有点问题 希望朋友们帮忙解决一下(matlab)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)
