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.)
