创建MATLAB 3d图

Question

I have a matrix let it be called ARR

size(ARR) = 3600 x 140

Where it stands for 3600 seconds, 140 nodes, and in each place ARR(t,n) = value

How to create a 3d plot to show this ARR?

When I do surface(ARR) I get nothing, and when I do plot(ARR) I get 140 lines.

How in plot(ARR) can I add legend to know which line has which color.

Answer 1

You can for instance use surf(ARR) or mesh(ARR) . See the documentation for further usage.

For your plot problem you can use legend but it may not be very handy with 140 curves.
