Re: Differential equation with Scilab question

O.K., Dale. I guess I don't know what is it that you are having a hard time with. Scilab has a built-in function to solve ordinary differential equations (ODE). Are you looking for something beyond that? Anyway, here is a short script that will solve your equation. // dy/dx=(x+1)/y, y(0)=0.1 clc fu...

Re: Differential equation with Scilab question

Hi everyone, Hope you can help. I have to set up scilab to solve a differential equation, but I don't know how to get started. Here is the equation. dy/dx=(x+1/y) , y(0)=0.1 Any help you can provide will be helpful. Also, this is time sensitive, so the sooner you can replay the more thankful I will...

SciLab for Nuclear Applications?

Does anyone have any references of SciLab being used for nuclear applications, i.e., to solve nuclear numerical problems?

Re: SCILAB Script - 12 Days of Christmas

Interesting, but how about posting any more practical pieces of code? Yeah, something more demonstrative of scilab's abilities in the context of this forum - energy, risk, safety, etc. would have been more interesting, I agree. There are hundreds, probably thousands of such scripts out there, Gradp...

Re: Is Scilab Good for computing?

Interesting read, but I am not sure how useful it is. So it tests Matlab, Scilab and Octave and has conclusions all over the place, making all sorts of qualifications about operating systems, and sample problems used and versions of the programs used. How does that help the person trying to determin...

Because I totally missed that in the package documentation :-(

Thanks!

Scilab - Cubic spline

I have to come up with a script to do some cubic spline interpolations. Does anyone have any pointers? It's part of a bigger project that involves the development of a variety of routines/scripts and I may have to bug posters here again, but for now I'm stuck and unless I can solve this problem I ca...

Re: Scilab 5.4.0

The new version of Scilab is awesome! I just wish that I was more familiar with it. Unfortunately, it's not something I use all the time, so every time I have to use it I have to re-learn lots of things. It comes back easy, but it still takes some effort.

Re: SCILAB 5.3.3

Anyone around here know what the difference between Scilab and SciCosLab is? I see references for both out there, and it's really confusing.

Re: SCILAB 5.3.3

Thanks, Johannes. I know the concept was very simple, I said so in my post. I was getting stuck on the very first step of declaring the matrix B. But, it turned out, it was my own confusion about using commas and semi-colons in the definition. I was declaring B=[1,2,3,4,5] instead of B=[1;2;3;4;5] w...

Re: SCILAB 5.3.3

Excellent thread. I am very new to SCILAB, having worked with a number of "classic" programming languages in the past, and I find it very powerful. While trying to learn how to use this wonderful tool, I am going through some simple applications and one of them is giving me a hard time. It's modelin...
