DFT
1)编写DFT子函数（计算并画出幅频特性），以后可调用。
2）N=32，M=32，128，256时，分析频率分辨率、频谱的光滑程度。
3）N=64，256，512时，分析频率分辨率和频谱的光滑程度。
(1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.)

Matlab-HW1
信号与系统matlab作业，实现卷积操作，供学习信号与系统的同学们参考(1. Define two signals as:
x1[n] =
n, 0 < n N1+1
2
N1 − n+ 1, N1+1
2 < n N1
0, elsewhere
and
x2[n] = 1, 0 < n N2
0, elsewhere
We let N1 = 999 and N2 = 500.
(a) (30 )Write a MATLAB function myconv to compute x1[n]x2[n] where
denotes the convolution sum. You have to plot your result and attach
it in your report. You may use the MATLAB function conv to check
whether your result is correct.)
