Mrdump*: Dump the matrix right hand side values to a file (or to console) -

General Form:

mrdump <filename>

If <filename> is given, the output will be appended to file <filename>, otherwise dumped to your console.

Example usage after ngspice has started:

* Dump matrix and RHS values after 10 and 20 steps
* of a transient simulation
source rc.cir
step 10
mdump m1.txt
mrdump mr1.txt
step 10
mdump m2.txt
mrdump mr2.txt
* just to continue to the end
step 10000

You may create a loop using the control structures (Chapt. 17.6).
