hi, i got a question about mna. i know how to write matrixes with(out) voltage source but i don't know what i should do when my instructor askes me placing vcvs or vccs instead of any resistor. i have lecture notes for vcvs ust like;

Vpq=u(mu)*Vkl

i should add extra rows and cols. to matrix of Y (or G, i don't know how you call it) but how?

by the way, i also want to know a way of doing same thing to voltage controlled current source.

For voltage/current controlled voltage source, just write down an additional equation relating the voltage drop in the voltage source and node voltages, plus another additional equation relating the node voltages and the control parameter.

For a current source, you only need to write down another additional equation relating the node voltages and the control parameter.
