Variable set_matrix_list
List Command
Function sets one of the four coefficients of the general transformation matrix M
of a list (see
Call
set_matrix_list( HeadNo, Ind1, Ind2, Mij, at_once )
Parameters
HeadNo
Ind1,
Ind2
Mij
at_once
Comments • The command set_matrix_list only allows changing one of the four coefficients at a
time. To change several coefficients during execution of a list, the command has to be
called repeatedly. Here, we recommend making the first calls with at_once = 0 and only
the last call with at_once = 1.

Row index and column index of the matrix coefficient to be changed as an
unsigned 32-bit value; permissible values: [Index uneven: 1, Index even: 2]
Matrix coefficient as a 64-bit IEEE floating point value;
Allowed range: [–50 ... +50];
if the parameter is set to an invalid value, the command will be replaced by a
list_nop.
This parameter (unsigned 32-bit value) determines when the defined
transformation becomes effective:
= 0: The transformation settings are only collected and intermediately
stored, but the transformation is not processed as long as this is not
activated via another coordinate transformation (e.g. via a list
command with at_once = 1 or a corresponding control command).
= 1: The transformation is immediately calculated (including all
transformation settings that were collected until then) and processed
prior to the next list command. The "laser active" laser control signals
will first be switched off if necessary.
= 2: The transformation settings are only collected and intermediately
stored (as with at_once = 0). However, The transformation is
immediately calculated (including all transformation settings that
were collected and intermediately stored until then) and applied to
the current position when the next jump_abs, jump_rel,
goto_xyz command is executed.
= 3: As with at_once = 1, but the laser control signals remain unaffected.
> 3: See at_once = 2
