2D Interpolation question

[george_geo56]

Hello PTC community,

I searched all over the internet, but i could not find a solution for my problem, with my limited knowledge of mathcad usage (civil engineering student).

I have attached a picture of my table that i have to interpolate the values. it kills me that I can not solve it.

i have looked at all topics about 2d interpolation, but i couldn't not understand to reproduce.

I will be very grateful for any help!

Hi,

Here is another method that means all you need is enter the two search values to get an answer.

I would improve this by programming the individual steps but have left it so you can see intermediate values.

The generic 2D and 3D interpolation routines I posted here  a few times may be of help.
Here is one post for Mathcad 15 -> https://community.ptc.com/t5/PTC-Mathcad/3D-data-fit/m-p/478836/highlight/true#M172637

or here with Prime -> https://community.ptc.com/t5/PTC-Mathcad/3d-surface-plot-from-excel-data/m-p/370013/highlight/true#M144823

For further help you would have to tell which version of Mathcad or Prime you are using and provide a worksheet with the table and vectors typed in.
