Hello
I have a problem with array. Now, I have xy, that is 640x480. Then I know the values of each z, that is 480 values correspoding to y axis.
I would like to ask that how can I make XYZ array.
I try to use cat already. But it is 640x480x2 (xyz) that is 2 pages, that the first page is 640x480 and the second page is z values. I don't know I can link the first page with the second page or not.
If you have an idea, please suggest to me.
Thank you so much

So x has 680 and y has 480 elements , correct?

Yes sir. And z values corresponding to y axis (along horizontal axis).

Thank you sir.
If I use cat, can I link the second page with the first page ?
Look like I create 3D array. I have 640x480x2. In second page, I have 640x480 same with first. Can I link the matrix the first page corresponding to the second page ?
If you could illustrate aiding a 2X2X2 matrix and state explicitly how it should look like, would be better.

Assume like this. I have XY plane like in this figure. And Z in my work is depth position corresponding to y-axis. Assume I will plot graph 3d, it means that I need to use Z but Z is in the second page.
I would like to ask that can I link the Z in second page to XY plane correspondng to y-axis in first page .
