3.5 Setting Up and Solving Circuit Equations 255
3.5.4 Solve
Solve[dae]
Solve[dae, var]
Solve[dae, {var , var , † † † }]
solves a system of equations given by dae for all variables
solves for one variable
solves for several variables
Command structure of Solve.
In order to symbolically solve systems of equations formulated by the function CircuitEquations,
Mathematica’s built-in function Solve has been extended to handle DAEObjects as well. Solve returns
its result as lists of rules of the form {{var −> expr
}, † † † }, where the variables var are assigned
symbolic expressions expr.
