With any edition of Chocolatey (including the free open source edition), you can host your own packages and cache or internalize existing community packages. Packages offered here are subject to distribution rights, which means they may need to reach out further to the internet to the official locations to download files at runtime.įortunately, distribution rights do not apply for internal use. If you are an organization using Chocolatey, we want your experience to be fully reliable.ĭue to the nature of this publicly offered repository, reliability cannot be guaranteed.

And in our next video, we'll move on to finding out how to proceed on that basis.Welcome to the Chocolatey Community Package Repository! The packages found in this section of the site are provided, maintained, and moderated by the community. So we've started, and we've made, some data. And lo and behold, the points are bigger. Making that size larger than it would be- let's say, 20- and running it again. I can actually change that if I want by telling it a string marker size. Again, the markers are rather unpleasantly small. And Lo and behold, it's changed it to a plot with points.

I'll change that plot by telling it that it's going to have points, and those points are going to have the form of a plus sign.

This is a line plot, which is a little bit annoying. That can be fixed in ways that I'll go into later, but we won't worry about it now. The labeling is rather too small, but that's kind of built into the rather poor graphics in Octave and MATLAB, for that matter. Actually, it's a bit inconvenient to see it in quite those terms.

Then I'll add to it some small fraction- let's say, 1/10th- not 0.1 times the sine of, let us say, 10 x. That would just give me a straight line, if I made it nothing but x. y, I'm going to make equal to x, let's say. And if I do that and save the file, then I see I've turned it into a column vector. So I can say, transpose the numbers 1 through 6 into a column vector and then divide by endpoints. I can transform a row vector into a column vector by taking its transpose. It's preferable that I have a column vector. And I can save that file again, run it again, and now, of course, my screen shows that it runs from 1/6 up to 1. I want it to run from, essentially, a small value up to 1. Tells me that x is 1, 2, 3, 4, 5, and 6.Īctually, I don't want it to run from 1 to 6. If I do that, what you see happens is, it tells me that endpoints is 6. I can save this file- it's called fitting- and then I can run it in Octave by just typing fitting. And so I do that by saying x is equal to 1 colon endpoints like this. And I'm going to make it be run from 1 to endpoints. And now, let's generate some x and y values. Let's make it a small number, so that it's kind of manageable. Let's, first of all, define the number of points I'm going to fit. What I'm going to do now is develop this fitting program. It's not quite the same as you would have if you're running MATLAB itself, but it's pretty similar. So now I'm in a situation where I, essentially, have my own IDE, integrated development environment. And I've opened Emax, and I'm ready to get started.Īctually, I'm going to run Octave simultaneously in the adjacent window. Let's say, fitting.m, is the correct extension for a MATLAB or Octave file. So I'm going to delete my picture from the screen now, and just show you the rest of the screen. Here's someone who's not an expert who can use this routine for carrying out the kinds of exercises that we want to do. I'm certainly not an expert at which is an open source equivalent of MATLAB, but that's part of the demonstration. I'm Ian Hutchinson, and the purpose of this short video is to give you illustration of how to use Octave.
