说明：  1.编制一个计算两个序列线性卷积的程序，计算y(i)=x(m)*h(n)，分别绘制x(m)和h(n)，以及线性卷积结果y(i)的图形，使用matlab自带的conv函数来验证结果。 2.使用matlab自带的FFT和iFFT程序，实现线性卷积的快速计算，并对计算结果进行绘制。(1. Make a program to calculate the linear convolution of two sequences, calculate y (I) = x (m) * H (n), draw the graph of X (m) and H (n), and the graph of the linear convolution result y (I), and use the conv function of MATLAB to verify the result. 2. The FFT and IFFT programs of MATLAB are used to realize the fast calculation of linear convolution and draw the calculation results.)
