How to reshape 'Z' matrix for surf(X,Y,Z)

Hi. I am fairly new to MATLAB and I am trying to use surf to plot 3D surface plot for my modal curvature. i have meshed the grid and my X and Y matrices are of size 2000X2000. I want to reshape my 'Z' Matrix so that it becomes of size 2000X2000 from 2000X4.

Where 2000 is the number of elements in my beam and 4 is the vertices of those elements

Edit-Thank you guys for response but i have tried reshape(Z,2000,2000) before asking here. It is not working. Also I am using AEM based modelling so there are no nodes but the springs used for elements connections.

"Where 2000 is the number of elements in my beam and 4 is the vertices of those elements"

That sounds like you should use PATCH, rather than MESH:

Hi @Ashish Srivastava,

You can use the reshape function.

updatedZ = reshape(Z', 2000, 2000);

"You can use the reshape function."

No, you cannot use RESHAPE to change an array with 8000 elements into an array with 4000000 elements.
