How to cross two 2d plots in a 3d view?

Using this code I acquire this figure 1 and figure 2 (attached). Do you have any idea about how to cross this figures in order to analyse data from a "3d" perspective? something like figure 3 (attached)

Hi,

try:

surf(x1,y1,reshape(z1,100,100))
hold on
surf(x2,y2,reshape(z2,100,100))

that give the following result:

.

I suspect that is what you wanted.

Best regards

Stephan

Thanks for your answer Stephan. Nevertheless, im looking for something like figure 3. My 2d plots like vertical slices crossing each other.

[Stephan]

how do you determine the cross line of both?

[Philippe Corner]

I was thinking on way where we could set any x coordinate from a figure to do it. for example to cross them at x=55 at the first figure. It does not matter that both black lines do not match at the same vertical axe..

thanks Stephan.

[Stephan]

Not sure what you mean - i guess:

surf(50*ones(length(y1)),y2,reshape(z1,100,100))
hold on
surf(x2,y2,reshape(z2,100,100))

gives:
