Convert coordinate trace into Nx2 numeric array.
x=double(t)
When given an imat_ctrace object, the DOUBLE function converts a coordinate trace t into an nx2 numeric array. The first column of the result contains the node number, and the second column of the result contains a numeric code representing the coordinate direction:
| Numeric code | Direction | Numeric code | Direction |
| 1 | X+ | -1 | X- |
| 2 | Y+ | -2 | Y- |
| 3 | Z+ | -3 | Z- |
| 4 | RX+ | -4 | RX- |
| 5 | RY+ | -5 | RY- |
| 6 | RZ+ | -6 | RZ- |
| 0 | any other |
A numeric array of this type can be used to create a coordinate trace by passing it to the imat_ctrace function.
>> t=imat_ctrace('5y', '6rx', '3z', '4x-')
t =
'5Y+'
'6RX+'
'3Z+'
'4X-'
>> double(t)
ans =
5 2
6 4
