Bilinear Interpolation

[aherrera]

Good day to everybody. Can anybody help me with an example of bilinear interpolation in mathcad prime please?

Hello Antonio,

I do not work with MathCad prime but MathCad 15 instead. The logic in the function should be the same though. You can convert this MC15 function to prime. Hope this helps.

Hello.  I am relatively new to Mathcad (15).  This double interpolation function works great.  However, upon close examination function, I noticed that local variable "i" is not used beyond its assignment in line #4.  Am I missing some "trade secrets?"

Thank you in advance.

Please provide your example.

Here is a sheet I once created as a reaction on a question here.

Inside the third collapsed area you find routines for bi- and trilienar interpolations

Hope it helps.
