i'm working with lot's of arrays and matrixes as datastructures in 

JS. with the max message size limit, it's nice to use jitter matrixes.

i could spill them in and allocate them like that, but JS seems so 

take function jit_matrix() as an input function.

how do i deal with it this way? can i copy it to a 2D array?

Do you have an example of what you're trying to do? Have you looked

Do you have an example of what you're trying to do?  Have you looked
at the Jitter/JS examples?

i have an array of objects (with an array in them), like this:

for (var i = 0; i < netsize; i++){    

i'd like to fill and spill them with matrixes coming from normal max.

no, didn't check the examples *blush*, sorry, but searched the 

so off to check them now... at first glance i see some output, but no

Looks to me like you're going to want to use the getcell and setcell

jit.matrix methods. They work just the same as in the patcher.

var mat = new JitterMatrix(1, "float32", 2, 2)

Looks to me like you're going to want to use the getcell and setcell
jit.matrix methods.  They work just the same as in the patcher.

var mat = new JitterMatrix(1, "float32", 2, 2)
mat.setcell(0, 0, "val", 4);
var value = mat.getcell(0, 0);

cool, but how do i do this with matrix input?

or do i have to refer to a named matrix -i believe you can do this, no?

atmof i use js just as a different language inside max, so i haven't

atmof i use js just as a different language inside max, so i haven't  
really explored the js max model world.

You need to have a matrix object for this, not just a name.

something like the above should work but I wrote the code in the email

function jit_matrix(name)
{
      mat.name = name;
      val x = mat.getcell(0, 0);
}

something like the above should work but I wrote the code in the email
so no guarantees.

ok, got it, so i can get matrixes in, then use the virtual (well you 

know what i mean) matrix object to link and parse it.

still, this strikes me as the only part of max which isn't documented 

am i missing something or is it in the pipeline?

I think the key is understanding what a Jitter object has (attributes

and methods) and how to itnerface with JS to those attributes and

methods. The second step is translating that understanding into how

to accomplish a particular task. In your case it was how can I access

matrix data that's outside my script. The answer is using a named

matrix which means creating a matrix object with the same name in JS

just like you would in a patch. The concepts are documented in the

Jitter HTML ref, akk that needs to be done is to mentally translate

that information to what you know about how Jitter objects interface

with JS. that's how I think about it at least.

yes, you're right and it's not unreasonable. but then on the other 

hand max is often credited for having excellent documentation, it 

seems that there is a need for bringing all knowledge together -if 

not explicitely then at least explaining the method. for example in 

my js .pdf there are a number of reserve function keywords, but 

i don't mind asking helpful people as yourself for some advice, i was 

just thinking of the max-msp workshops i'm teaching later this month.

yes, you're right and it's not unreasonable. but then on the other  
hand max is often credited for having excellent documentation, it  
seems that there is a need for bringing all knowledge together -if  
not explicitely then at least explaining the method. for example in  
my js .pdf there are a number of reserve function keywords, but  
jit_matrix() isn't one of them.
i don't mind asking helpful people as yourself for some advice, i was  
just thinking of the max-msp workshops i'm teaching later this month.

Ah. jit_matrix isn't a special method at all. That's how matrices are

actually passed around the patch and this *is* documented. In the JS

PDF it states how to call JS functions from the patch. You name a

function and set it a message of the same name with arguments to

follow. jit_matrix is a convention but the name could be arbitrary.

If you hook a print up to the outlet of a matrix object, you'll see

jit_matrix u398439843 or something like that. The first part of the

message triggers a function call (jit_matrix) and the u398439843 is

the argument. You could actually change this to

function jit_matrix(in), how to handle it, not documented?
