dim variable(rows, columns)
|
| See Also | reshape , rowdim , coldim |
dim statement to change the dimensions of an
existing matrix. If you enter
y = seq(12)
dim y(3, 4)
print y
the dim statement places the first three elements of the
sequence in the first column of y,
the next three elements of the sequence in the second column of y,
and so on. O-Matrix will respond
{
[ 1 , 4 , 7 , 10 ]
[ 2 , 5 , 8 , 11 ]
[ 3 , 6 , 9 , 12 ]
}
If you continue the example above by entering
dim y(2, 6)
print y
O-Matrix first converts
y to a vector in
column major order
.
O-Matrix then converts the vector into a matrix with
the specified dimensions.
[ 1 , 3 , 5 , 7 , 9 , 11 ]
[ 2 , 4 , 6 , 8 , 10 , 12 ]
