PrintA Command

This command is used to print the current global system matrix. The limitation of the command is that the system being used must be a FullGeneral

printA <-file $fileName>



$fileName (optional) name of file to which data will be sent. overwrites existing file. default is to print to stderr)

NOTES:

The printA command can only be issued after an analyze command; it will invoke formTangent() on the integrator and spits out the result of theSOE->getA(). As a consequence, the output is either a transformed K matrix or some transformed combination of K, C and M. what the transformation is depends on the constraints and the constraint handler;

As previously stated, the system used must be a FullGeneral.

EXAMPLE:

printA
