Thanks alot. I was exctly looking like this.

(1) I tried to run your statements and its giving me an error

Error, (in plot3d) at least three arguments are required

(2) How did you come up with

     what is the Math behid it? Just need hints and I will figure it out.

@Carl Love 

Thanks for your help. It works for me.

@Carl Love 

yes, its typo (copy & paste). It should be Y<=20.

@Carl Love 

Yes, six different surfaces where 0<=x<=10 and 0<=Y<=20. I also forgot to mention that set of data is generated by a loop as

for (double X = 0; x<=10; x+=0.5){

    for (double Y = 0; Y<=10; Y+=0.5){

            ------  calculations ------



The values given for X in my previous post should be 0, 0.5, 1, 1.5, ........

@Rouben Rostamian  

Thanks for the code and all those who helped me and commented on the code. This is what I was looking for in continuous case.

Can you (anyone) do one example for discrete case?

@Markiyan Hirnyk 

In convolution we move one graph from the left and slide over the another one. As they concide in the region where f(t-k)g(t)<>0, we start getting nonzero values for convolution. Please check this link, I need to produce the same animation as shown in



@Markiyan Hirnyk 

Thanks for the possible solution. Basically, I am looking for a plot which displays both functions and the convolution. As f(t) moves from the left side and concide with g(t), it should start display the convolution result. Thid would help to explain the convolution.


what is the pupose of Typesetting? and Why we need to include?


I used your example, but it is giving me error.





Thanks, I appreciate your quick response.


How would I draw if the surface is bounded by different domain. For example, draw a solid under z=xy where the base is bounded by y=2x and y=x^2.



Thanks, I think my office computer had display problem. It worked out at home computer.

@Markiyan Hirnyk 

Thanks for showing two working example. But unfortunately I am using MAple 17.02, 2013 and it does not have shadebetween().
