Thank you.

Hi there many ways for this. in addition of Tuagal post :

1/ If you know the elements of the matrix, just enter it in your program :
[[ 11 21 ] [ 12 22]]

2/ Create a 6x6 identity matrix :
6 IDN

3/ If each element is a function of I J (Line, Column)
6 6 « 10 * + » LCXM @ Create a 6x6 matrix [[ 11 21 31 ...] [12 22 32 ...] ... ]

4/ If your matrice is a variable, for example M you can use this syntax
99 'M(3,5)' STO
`M(I,J)` returns immediatly the value of I columns J row of M
Slower but more readable in many cases than the PUT and GET command

Etc.
