Re: Scilab exponential interpolation

Thanks, everyone. I do understand what everyone is saying about how to interpret and use statistics, in general, but I think everyone missed the original request, i.e., if anyone had a scilab script for exponential interpolation :-) In any case, I am working on putting one together right now. If I ...

Re: Scilab exponential interpolation

Not sure what other detail you are looking for, I think it's very simple. A scilab routine to do exponential interpolation.

Re: SciLab - Linear algebra

Thanks, very interesting, indeed. The more I learn about scilab the more impressed I am.

Learning a lot on this forum!!

Re: LSF single-multi variable in scilab

Any good sources (documentation, examples, etc.) for doing LSF data fitting in scilab? Rob, I am fairly new to this, like you, but when I was looking for an interpolation function, I saw dozens of documents about lest squares fit. They didn't help me and I can't say that I understand them, but you ...

Re: Scilab exponential interpolation

Not sure if this helps, but I found this folder with a whole bunch of docs, on this board and there is a document there about exponential interpolations Doc: Exp_Interpolations_Karahalios.pdf Link: ( http://triusinc.com/techs/Exp_Interpolations_Karahalios.pdf ) Take a look and see if it's what you ...

Ahem, pay attention to the axes. That's a straight line on a semi-log plot, i.e. it's an exponential type function! Try plotting the values on a linear scale.

Re: Scilab exponential interpolation

Sorry, it's clear to me, so I thought everyone understood (just joking). O.K., here is the problem. I have a bunch of measurements (23 pts) from an experiment. I can plot them and I can tell that there is an exponential type curve (straight line on semi-log plot below). So, I can try and fit a LSF c...

Scilab exponential interpolation

I mistakenly posted my question in different thread (sorry about that), so I am re-posting here. First, this board is great. I find better answers here than what I am finding in the scilab specific forums. I guess those other forums are for people that already have expertise on the subject. I also h...

Re: Differential equation with Scilab question

This is great. I find better answers here than what I am finding in the scilab specific forums. I guess those are for people that already have expertise on the subject. I also have a question. Does anyone know of a scilab script for doing exponential interpolations? Thanks in advance for any help.
