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.
