Use the menu Input > Create Table Matrix Palette and fill it with the desired numbers tp get the matrix. Then write for example naturally beside it [[3,1]] . That will give you the element of the 3d line and first column. Out[60]= 7 These ordering conventions are the usual ones Jacqueline Zizi ------------------------------------------------------------------------------------- Stephane Hebert wrote: > Hi folks, > > Ok, let's say I have this > > 1 2 3 > ----------- > 1| 1 2 3 > 2| 4 5 6 > 3| 7 8 9 > > A 3x3 matrice or array.
