MATLAB: To equate one value to another

Question

Hello! I have signal values ​​(floating values) how do I equate them to the depth of this signal?

signal values ​​800 801 702 and up to 2000 depth is 14 15 11 and so on until 2000 what could I do then as a result 15 -5 and for my signal it will be like 800-264

Help me please!

Answer 1

May be like this:

Let S - your signal.

m = min(S);
detph = 10/(max(S) - m)*(S - m) + 5;
