How can I define multi-dimentional array in classpad for programming?!
for example how can I have such a table with m row and n col

input n
input m

and then how can I fill the table with m*n cells with "Input" ?!



1 2 3 4 5 ... n
1
2
3
4
5
.

.
m

thanks a lot

fill(0,x,y) creates a new empty array with x rows and y cols
fill(a,x,y) creates a new array with x rows and y cols, filled with values "a"

you can also use [[1,2,3][4,5,6]] to refer to the 2x3 array containing :
[ 1 2 3 ]
[ 4 5 6 ]

Hi,
A very simple solution in 2 Steps:

1. Open your complete PDF ClassPad Manual;
2. Read the section about matrices carefully.

Great! It's what I always tell in the French forums (all hate reading manuals)

Okay, if you are lazy or tired of reading your manual:

fill(0,5,6)=>array
Input array[4,3]

This is not complicated...
