I'm trying to make a function return a value from a matrix by running a small for-loop inside the function. How should I write it? Couldn't find examples how to use it.

Hi Mikko

The loop syntax needs tweaking, and the output variable needs to be defined. The attached file works for me.

Thank you!!!

Greetings

I have not been able to understand the purpose for which the imagined algorithm is used. As the question arises, it is a case of express identification of a certain value in the "kertoimet" matrix. In this case in 99.99 (9 ...) of cases, the result will be an error. If so then you can avoid ambiguity using the first procedure (case identification) in the attached file. Looking at the problem in terms of practical use, in the first column of the "kertoimet" matrix there are some non-dimensional coefficients corresponding to circular x-ray surfaces with the area expressed in square millimeters. In this case, a linear interpolation of these coefficients would be useful depending on the radius of the circle, and the procedure is the one presented in the case of interpolation.

... sorry: I understand nothing in there. Too few information.
Yes, you can best fit a circle from few points [not done in Smath]
