i see that i can use print object to the right outlet of jit.matrix 

can i display them in number boxes with unpack or something?

**unpack shows only the cells and not the value!!! ***

Using an [unpack 0 0 0 0 0 0 0 0] should do it - after all, the output 

from jit.matrix when it receives a getcell message is "cell x-coord 

y-coord val A R G B", if I am not mistaken?

i checked the help files and tutorials but i dont understand why to put "prepend set" in unpack!!!

also, when its grayscale matrix (with jit.rgb2luma), the values we have arent ARGB ?

I am bit confused although i read the tutorials..

- set is the message that the object called "message box" understand. 

When this message is received the "message box" will change it's 

contents (display something else). The prend object puts whatever it 

receives after the "thing" it has as argument.

- jit.rgb2luma convert a 4 planes matrix (ARGB) into a 1 plane matrix 

(Grayscale), based on luminance. So at the end, you'll have only 1

i don't know why you want to display cells in a number box. of the top of my

head i think that should only be used as a debugging tool, and not part of

check jit.cellblock also. i used it to understand a matrix all the time. not

i don't know why you want to display cells in a number box. of the top of my
head i think that should only be used as a debugging tool, and not part of
an efficient patch.

check jit.cellblock also. i used it to understand a matrix all the time. not
in actual patch.

i want to display cells in number boxes cause i dont know yet any other way to control midi messages through webcam triggering..

i want to do simple things...when something from webcam touchs a cell (or a series of cells) to trigger midi!!

also to get values from a region i used submatrix, but the offset 

attribute enlarges the matrix only to the right!!

how can i select a specific location with submatrix??

i take it back, for what you do thats a good method as any.

look at tutorial 14 (i think) for matrix repositioning.

you can also use a combination of scissors+ glue+ jit.3m
