Dear Python / Dynamo experts,

Is it possible to get iteration from the list below by input value for X and Y and get value from table by iteration.

i.e:

X=4.3

Y=5.8

Result: **5.2**

Can you please elaborate on what you want to do?

There is nothing in the Mathematical Dictionary called Iterasion?

Do you want to carry out a Linear Interpolation through Dynamo?

Also posting an image is not going to get your problem solved.

*(To be honest, nobody would type in those 120 values from an image and then try to find a solution for you)*

Next time try posting an excel sheet or something alike and that will at the least get you started!

@kvusal

you probably mean bilinear interpolation

you can do this mathematically or geometrically- the below is the geometry approach

I end up with 4.04- not sure how you got 5.2

As @AmolShah says, I’m not going to type in the numbers, so might have made a mistake- but that is the principle

postscript: mine corresponds (nearly) with https://structx.com/Bilinear_interpolation.html

You can get 5.2 when you carry out a linear interpolation between 4.4 and 5.4 taking in the input as 5.8 which doesn’t make any sense since this has to be bilinear.

Well Done.
