Greetings!
What Origin tool can I use to find the optimal linear transform parameters (y = kx + b) to match a given pair of signals (see an example below)?

Dear James,
Got it.
Thank you.

Dear James,
Works perfectly!
Now I see the principle of operation.
Thank you.
BTW, does Origin have the functions similar to those provided by Optimization Solver app?

Dear James,
Is this possible to optimize both parameters k and b?
I realize that k is negative, but not sure that it is equal to -1...

Dear James,
X-coordinates are not the same.
In fact the task is to find k and b – the parameters of the linear transformation of the X.
