Cáculo complex mathematical style Matlab in the Palm
We already saw in another post how to turn the Palm into an exact replica of a graphing calculator HP, through the emulator Power48. But there is another way to perform complex calculations with our PDA, and is using Lyme, a kind of Matlab for Palm.
Matlab can draw and represent complex calculations
All they have to, for their work or studies, perform complex mathematical calculations, you probably already know Matlab. It is a programming language, based on the calculation matrix, which allows developing all kinds of intense calculations more easily than using a general language like C or Java. Its applications are infinite in mathematics, process control, data analysis, financial analysis, signal processing, image processing and voice, and so on. LyME is a program that remains the same intention, and runs on the Palm. There are a total of 480 instructions and operands native functions, most compatible with Matlab, as well as the possibility of creating libraries that extend its capabilities.
The program can be downloaded for free from its website. The installation of Lyme does not have any difficulty, through a hotsync installed math libraries for Palm (mathlib.prc file) and the program itself (LyME.prc file). The remaining files that accompany it, are additional bookstores, extending its functionality.
Lyme returns the results as both numerical graphically
Once installed, it will use the same way you would do with Matlab: write the code, and pressing the "Eval" the program will be implemented. We can see the (huge) list of all the features available in the program by clicking the word "Fn" (to function) in the lower right corner. In the case of graphs, switches between the graphical and text mode with the buttons that put "G" and "T" respectively, are located at the top of the screen.
To see examples, puldamos the button "Ld" and we will show the libraries installed. We chose the so-called "demo" and will open a submenu, with a few demonstrations. We tried all go and see the result. Some ralizan calculations, others draw simple graphics. In each one, it shows also that the code has executed, so it's a good way to learn to use the program. As an example, I wrote the code that evoked on screen function sync, and the result to run on LyME:
x = (-50:50);% defines a vector x = [-50 -49 -48 ... 48 49 50]
y = sin (x). / x;% definition of the role sync. The "." it is necessary
plot (x, y, 'r');% draws the role, in red
Drawing the function "Sync"
Lyme, like Matlab, it has endless possibilities. It pays to read the complete documentation to be prepared on the agenda. And to open his mouth, some sections that I have drawn attention: the possibility of using the infrared port and bluetooth from our programs in LyME and access files on the Palm and on the expansion card. And then they say that only apply to Palm quotations point.

Marcos, only it came with another question and I come and I find this interesting posts you've published on math applications and the turn toward giving Palm Linux, I've left open-mouthed master. Congratulations and my respect for that has been turning on my visit for issues relating to the wonderful world of Palm. Thank you!
Anyway, the question. It turns out that my girlfriend and your server we have just learned that we are going to be parents for the first time. ¿Could suggest some applications that load on our Palm to continue the development of the baby and also applications for post-partum care related to the baby?
Thanks in advance and I hope your answer.
Luiz Hello, I am grateful for your kind words and I am glad that you are interesting topics that deal.
I felt very good the theme of motherhood and Palm, so I wrote a post on the matter. I hope you will be useful
A greeting.
As I would have loved to have this sw in my school days
Greetings
Wow simply great.
I use (not very often, but I use) Matlab.
But now it will be easier.
True, many believe that the palms only serve to gender events, what was lost.
HoLaS ... so I see the worst LvME is very good as I get one of these for my palm ?????
Easy. You go to this page, download the program, unzip it and install all the files normally *. prc and *. pdb is in the folder to install the Palm.
thanks frames and install the program ... but I get an error every time I want to get out of it (fatal error) and I have to reset, what should I do? ...
Well, I do not know. It is not a program you need as much RAM as for hanging the Palm. Verify that there is enough free space on the Palm, but the truth is not what happens to be me.
hello again made a mistake ... wanted to install the files. EXE are not necessary? because only save the prc and pdb files ...
EXE file is provided for PC, and a PRC or PDB for Palm. Only those who have a need
