plot convolution of two descrete signals in matlab

main.m
% define the two discrete signals
x = [1 2 3 4];
y = [4 3 2 1];

% compute convolution of x and y using conv function
conv_xy = conv(x, y);

% plot the convolution
stem(conv_xy)
xlabel('n')
ylabel('conv(x,y)')

main.m
% define range of n values
n = [0:length(x)+length(y)-2];

% compute convolution of x and y using conv function with range of n values
conv_xy = conv(x, y);
conv_xy_n = conv(x, y, 'full');

% plot the convolution with n values
stem(n, conv_xy_n)
