MATLAB学习(二) MATLAB多维图像之一元函数的绘制 MATLAB的绘图步骤为:1、输入图形的数据信息;2、调用绘图函数进行绘图;3、设置图形属性,包括标注,颜色,线性;4、图形输出 一般二维图形的绘制命令为:plot(X,Y);其中X是自变量数据,Y是函数值数据,且X与Y是同维元素个数相同的向量。 注1:plot()命令是一元函数绘图的...
An example spectrogram for recorded speech data is shown in Fig.8.10. It was generated using the Matlab code displayed in Fig.8.11. The function spectrogram is listed in §I.5. The spectrogram is computed as a sequence of FFTs of windowed data segments. The spectrogram is plotted by ...
