How to apply time reversal convolution?

Greetings,

I have an impulse response of Hn = [4 2 1 0.5] and input signal of Xn = [2 1 -1 -2 3]. I would like to apply time reversal convolution to obtain the output signal.

I already reflect the impulse response and now it turn into h[-3]=0.5, h[-2]=1, h[-1]=2 and h[0]=4. my question is that how to apply time reversal convolution between the reflected Hn and the input signal??

   Yn = conv(Hn,Xn);
