Linear interpolation 2

Can you post the actual sheet?

Here it is (in MCAD 15 format) or here:

I don't understand what you are trying to do. linterp accepts arguments that are VECTORS, i.e., arrays of numbers.

po and mo are clearly defined in your example as FUNCTIONS. Since you already have po and mo as functions, there is no need for an interpolation.

The example I show is simplified, the real functions are more complex involving some programming, array summing and other functions. I want to store results of two functions (for x:=1..10 e.g.) in arrays so I can do interpolations between. Alternatively, I could solve equation P1=po(x) for x1 and then calculate M1=mo(x1) which is cumbersome in case of multiple calculations.
I imagined with given range of variables mathcad stores function results in arrays, just like plotting XY graph. Do I need a 'for' loop? I am just getting familiar with mathcad, so don't really know exact syntax.

No, you simply haven't defined any arrays yet. see attached

Great! That makes all clear. Thank you very much!
