[SOLVED] Help me plot lollipop figure in Matlab

[hgphtgi2]

hi all, could u help me to solve the following using matlab

x(-3)=1,x(-2)=-2,x(-1)=0,x(0)=3,x(1)=0,x(2)=2,x(3)=-1

h(-2)=-1,h(-1)=2,h(0)=0,h(1)=1,h(2)=-2

a) plot lollipop figure of x

b) use MATLAB to find convolution y=x*h

c)a) plot lollipop figure of y

a) I'm assuming you mean a stem plot..
x = [1,-2,0,3,0,2,-1];
n = -3:3;
stem(n,x);

b) type "help conv" in matlab console.

c) follow steps in a).
