Adding two graph using convolution

Hi everyone, I have two plot and I want to make the single envelope of the two plot. I think convolution do this but I don't know how I can use convolution. I have also attached my plot. Kindly provide me the idea about this Thanks in advance Sanjay

    X1 = asind(index_medium*sind(G1_plot_theta));
    plot(X1+G1_recording(1),G1_efficiency*100,'b')
    hold on
    X2 = asind(index_medium*sind(G2_plot_theta)); 
    plot(X2+G2_recording(1),G2_efficiency*100,'r')

" I have two plot and I want to make the single envelope of the two plot. I think convolution do this but I don't know how I can use convolution"

Convolution is not the same as envelope, so it is not clear what you want to achieve. If you want an envelope, why not ask about that?

If you just want to do convolution (as you say in reponse to the answer below) then

doc conv

is a good place to start!

Are you want to just add the two plots? If yes then Just add the two plots like y1+y2

plot(X2+G2_recording(1),(G1_efficiency+G2_efficiency)*100,'r')

Please Note: G1_efficiency & G2_efficiency must have same length

Hi Kalyan.I do not want to add these graph. I just want to make a convolution of these two graphs expecting the peak will be at the same position on x and y-axis.

Hi Kalyan, I want something like the green graph without changing the two peaks. Which function will so this..I was wondering that convolution will do that
