Linear Interpolation from one column of a matrix

Hi,

 

I have X & Y defined as two matrix variables, which I can do a linear interpolation between them...

 

How can I perform the same interpolation if I have X & Y in a combined matrix, ?

I am attaching the Mathcad file

You can use the 'column operator' to select/copy a column from a matrix, keyboard shortcut [Ctrl-Shft-C].

    Thanks @LucMeekes  

     

    I wanted to perform interpolation within the matrix, not just splitting it into columns. However, I used your technique and built the next step of the actual interpolation and it works... Thanks a lot.
    I just wanted to show you what I did with the interpolation itself in light of your help, which I assume is what you meant; unless you have a different approach just to learn from it ...

    Thanks and all the best!

    You did it correctly. If you don't want to break up the matrix, this:

    is the way to do what you want.

    Note that I used ORIGIN in my example, and you've used it also. It is the safest way to point to the first element (or column or row) of an array.
