Dear members,

I'm trying to store more than two data values in one array.. is this possible?
For example,
I have x values - time
and then multiple frequency values that I want to store under that one time value, then I want to be able to read out the data.
Plus it would be great to add amplitude data from fiddle... rather than using a whole new array.
Any ideas?

Thanks,
Stuart

I'd say this was a prime candidate for Pd's data-structures. but i've never used them...

another way:

say you have 3 frequency values and 1 amplitude value making 4 values total
then you can interleave them, so for example your array would look like this:

0 f0
1 f1
2 f2
3 a
4 f0
5 f1
6 f2
7 a
etc

but then make sure you use tabread and not tabread4~ because the interpolation will not work as you want.

btw, what you want is a 2d array, because you have two dimensions (time, variablename)

Thanks,

But what i'm not sure about is about tying several frequency values / amplitude data and time, what you suggests solved two value combinations but not a third or even a fourth.
And was what you were suggesting reliant on a single array table?

Again thanks for your help!

If you want to go more than one or two use datastructures as Claude suggested.
Reading this might be a good place to start.

Thanks for your help the article was very helpful, I found PD's own help files a little confusing.

Do you know how to retrieve a particular value from the data stored in a struct? With a pointer it is possible to traverse a list in a sequential way and to reset the pointer to the beginning... but is it there a way to recall a particular value or to search a struct for particular values and output them. I am not interested in using this in a graphical way (like most of the examples work with), simply numerical?

Unfortunately, that's how linked lists work.

Did you ever read the "Top Tips" section in Viz ?

anything, just follow the string until you find it"
