error: test.mtx: can't open
error: matrix: failed to read test.mtx

Hello, thanks for the help.

Where to get the file test.mtx?

Thank you.

@funkheld No, sorry, I don't know.
If it looks like what you are looking for then you probably need the complete iemmatrix library and maybe some other libraries as well.
The easiest way....... http://puredata.info/downloads/pd-extended
The middle way..... use Deken (in Pd 0.47.1 go to "help" menu.... "Find Externals")
Probably the hardest....... https://git.iem.at/pd/iemmatrix or
https://github.com/iem-projects/pd-iemmatrix

@funkheld Data structures [struct] could be used for this.

@ingox But not very easily..... which is why I didn't go there!......
Where the OP is uncertain about arrays I try not to dig them too deep a hole.
It's very worthwhile learning about Data Structures..... but probably the most difficult thing to understand in Pd! There was even (one-sided) debate about dropping the documentation........

If the OP is interested then this is the best "entry level tutorial" that I have found......

@whale-av You are right. I was just teasing, in case there would be any interest in the topic. And to make the thread more comprehensive for future visitors.

hello all , thanks for help.

Since what you need is indeed a matrix, I guess [mtx] from the iemmatrix library would be the best solution. The image below shows a basic use of [mtx]:

Hello, good evening.
In the folder everything is in it:

D: \ purr-data \ extra \ iemmatrix

It does not work.

have :
Pd-l2ork-2.1.2-windows-i686

Thank you.

@funkheld you are declaring a relative to your patch path, I think it should be -stdpath, which is relative to Pd

hello, good day.

this not funktion.

thanks

On purr-data I did [declare -lib iemmatrix] and then put a [matrix] object instead, not a [mtx] and it worked. Try it.

Though I tried the same patch in purr-data and it doesn't work the same way it does on vanilla. don't really know why, I'm not using purr-data anyway.

if you have:
working directory is C:\Program Files (x86)\Purr Data (in my case)
or
working directory is d:\Purr-Data (maybe in your case)
in the console window
then [declare -path extra/iemmatrix should work

I also noticed you have a colon missing after the drive letter d in your screenshot

hello thanks.

is ok.
