I would like to read 9 sub-matrices from a 16*16 matrix.
A [0,0] [6][6]
B [0,6] [6][4]
C [0,10] [6][6]
D [6,0] [6][6]
E [6,6] [6][4]
F [6,10] [6][6]
G [12,0] [4][6]
H [12,6] [4][4]
I [12,10] [4][6]
Does anyone knows a function which automatically reads the matrices if I define the starting point?
later if I can read the sub-matrices I want to create a [3][3] matrix with the means.
