Assuming that for the given responses underlined element has '0' index i.e for
h[n]=[1 -1 2] index is nh=[-2 -1 0]
x[n]=[2 1 2 3] index is nx=[ -3 -2 -1 0]
the matlab code is
%==================code=============
% [y,ny] = convolution result
% [x,nx] = first signal
% [h,nh] = second signal
%
h=[1 -1 2]; nh=[-2 -1 0];
x=[2 1 2 3]; nx=[-3 -2 -1 0];
nyb = nx(1)+nh(1); nye = nx(length(x)) + nh(length(h));
ny = [nyb:nye]
y = conv(x,h)
%================================
the convolution output is
y[n]=[2 -1 5 3 1 6] index n=[-5 -4 -3 -2 -1 0]
