I wanted to upload a program of mine to the archives, and it says that a download is required. I was looking for a converter, but I couldn't find one that worked. I was wondering if any of you have one that you use to convert files to upload them.

Thanks,

rmd(i:9)=rmd(i:9)-qd(1:10-i); % this is the syntax I need an equivalent for

polynomial fraction
0.2/(z^4-0.4z^3+0.646z^2-0.243z+0.024)

this is the code for the power series up to 9 terms.

rmd= [0.2 0 0 0 0 0 0 0 0]; %numerator coefficient
q= [0 0 0 0 0 0 0 0 0 0]; %quotient
qd=[0 0 0 0 0 0 0 0 0 0]; % product of quotient term with denominator
d=[1 -0.4 0.6465 -0.2426 .02426 0 0 0 0];%denominator

rmd(i:9)=rmd(i:9)-qd(1:10-i);
r= [0.2 0 0 0 0 0 0 0 0];
q= [0 0 0 0 0 0 0 0 0 0];
qd=[0 0 0 0 0 0 0 0 0 0];
d=[1 -0.4 0.6465 -0.2426 .02426 0 0 0 0];
rmd=r;
i=1;
for i=1:9
q(i)=rmd(i)/d(1);
qd=q(i)*d;
rmd(i:9)=rmd(i:9)-qd(1:10-i);
end

Take a look at TI-83 Basic Home - the main color is grey with a small hint of blue grey at the top.
68k TI-Basic Home - a more olive color, but still very monochrome-looking.
TI-Nspire Home - Brown.

These are great, and the color palettes reflect the calculator those pages were made for. But I don't see one that reflects the TI-84+ CE. Now, I know that the CE uses almost all of the same commands as TI-83 Basic, and there doesn't really need to be another Home for the color calculators, but it would be nice to see more colors added to the palette.

Take this suggestion for a grain of salt; it's not important, functionally, but it would be nice.

The programs must be written in TI-Basic or hybrid basic (i.e. not solely assembly or C). If you know of a particularly worthy program, please nominate it in this thread, and explain why you think this is a good example of the skills fostered at TI-Basic Developer.

Can anyone help?

1. Ti-83/+ only programs have to be listed as ti83/84/se, even though it runs too fast on those later machines to be usable.
2. People who list ti84 programs as ti-83 compatible, even though it runs too slow to be usable.
3. Some programs I found were "Ti-83 compatible" but have ti-84 only commands. They don't or barely work at all. (Even if you don't use emulators, this is a very obvious issue)

As someone with only a TI-83+, these can be frustrating.

I recommend that:

1. The site adds options for each calculator group.
2. Programmers test their programs for usability before saying it's backwards or forwards compatible. If an obvious lie is found, then they should change the form. (If you don't want to use emulated ROMs, then at least assume that there could be a speed issue)
3. If you program on an 83+, or a regular 84+, add an option (if possible) to change a loop variable or something for later calcs that slow down the program enough to be playable.

Any of you guys that have any updates in mind?

Command creation in action

• Easier to use and cleaner layout
• Command pages will now be listed easily with the use of the ListPages module (rather than typing and organizing every single page)
• Easier for new people to use (some may create a command page without knowing there is a template, this will allow them to create the command template and have everything organized for them).

CONS

• Limited to what the form has (some commands may have an applicable Formula section, but many others won't).
• Much work to replace the commands
• Limited and hard to workaround structure (for example, it may rarely be hard to properly format the columns, otherwise this shouldn't be a problem).

I haven't migrated the command pages to this format, mainly because I want to hear your opinions. Improvements, agreements, disagreements? Leave a post so I know if this is a good idea!

Is there a manner that I can take a set of data points in the form Pn(x,y,z)…from a spreadsheet application and draw a line from Pn(x,y,z) to Pn+1(x,y,z) from the spreadsheet data?

I'm having difficulty finding a decent programming manual for the TI Nspire; does one exist? There seems to be a real lack of methods to enter data.

Fortunately the handheld spreadsheets work very well for data entry for my frame program data, so far.

Thanks in advance, Dik
