3D Plot Input Data

[TW_9152075]

Hi there,

the PTC Mathcad help say if i want to use a matrix as Input Data for 3D Plots there are 2 ways:

• A 3-column matrix, where the three columns represent the x-, y-, and z-coordinates

• A m*n matrix, where the cell’s indices represent the x- and y-coordinates and the cell values represent the z coordinates

I need the first one, but my Mathcad (using Mathcad 15) allways plots my matrix like the second case.

How can I change this and tell the Plot that my matrix has the coordinates in the collums and not int the indices and values?

thanks a lot ❤️

Hi,

thanks, thats what I was aiming for 🙂

Please see the worksheet provided. The first plot uses the CreateMesh() function, a fast and preferred method for creating 3D plots.
The matrix is unrolled for the second plot, resulting in three columns of data: x, y, and f(x,y). You'll notice how time-consuming it is, as well as how the plot quality suffers.
