How to plot a two-dimentional matrix?

[ptc-4676289]

In Mathcad we can easely plot a two-dimentional function z=Z(x,y)

Is there a way, to plot a two-dimentional matrix z=Mj,j ?

Thank you!

Sure, if you are happy with the indices i and j to be taken as x and y values you can plot M the same as f via quickplot (= simply put M in the placeholder of the 3D-plot).

If not you would need the vectors of associated x and y values and would have to create a data structure of nested matrices like createmesh() produces.

Thank you very much!

One way to do it: M[i, j -> f(x, y) -> Surface

or Mathcad Prime

and the plot

Thank you very much, Valery!

Find attached some ways to plot data matrices:

1) Quickplot

2) nested data arrays

3) turning the matrix into a function using

a) linear interpolation, or

b) cubic spline interpolation

Hope you find soemthing which fits your needs.
