What am I doing wrong in ltspice?
Wimberleytech:
For whatever reason, it does not like the I(R1) expression. Use a voltage source with zero volts instead.
<<update>>
It converges if there is no multiplier while using I(R1).
I have increased the iteration limit to 3000 (with gain of 100) and it still does not converge.
Hmmmmm...
iMo:
Try with current controlled current source.
F1 is the CCCS, controlled by the current flowing via V2, the gain=100.

I concur. The CCCS worked for me as well. I suspect that a current source with the directive I=I(V1)*100 will instantiate in the matrix just like and F element would.
I am still puzzled why the original post does not work.
iMo:
@Wimberleytech: But you have got a typo in your schematics - the current is I(V2)*100.
I think the F converts differently..

|O oops you are right. It still converges once I change it to V2.
As far as how the matrix is instantiated...that was just a guess, but an educated one.
When I run them together I get exactly the same result.
