来自mini2440的s3c24xx的按键中断驱动(driver code copy from mini2440)

说明：  目前的代码是一个matlab函数，它提供给定信号x[n]的短时傅立叶变换（stft）。该函数是matlab命令“光谱图”的一个替代项。功能输出为： 1）一个具有复杂stft系数的矩阵，该矩阵具有跨列时间和跨行频率； 2）频率矢量； 3）时间矢量。 为了阐明函数的用法，给出了一个示例。为了方便起见，输入和输出参数在函数的开头给出。(The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command spectrogram The output of the function is 1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows; 2) a frequency vector; 3) a time vector. An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.)
