I'm having a little difficulty using matrices. How can I tell SMath to take the first row value from matrix "Pin" (0,2) and calculate formula "C0,2" with each value from matrix "Tin". I then want the result displayed as a new matrix 1x6, if possible (see pictures below). Thanks!

Here is what I want to achieve:

Quite correct, you can plot the family vs the Pin.

... more for your project.
You have to work the units that were ignored in this demo.

I cannot, for the life of me, figure out what this means:

Can someone lend me a hand with this? Thanks!

Edit: I seem to have figured it out.

A humble suggestion,
Putting vectorize into function prevents further writing errors.
And a subjective perspective, it also looks better.

As you give it, there is no immediate suite [interpolation ...]
As given not sorted, the suite is the "Colibri" path.
Once sorted, you can linterp, only.
You can also fillet at will polyline CAD style.
From there, fit and you have something much easier to understand.
You can even have a surface plot.

New head-scratcher with my project. The circled value should be equal to 34,8 not 34,7. I am open to suggestions where my mistake might be. See screenshot:
