transistor: The Transistor Amplifier, Index 1 DAE

Description

Electrical circuit model for the transistor amplifier.

It is an index 1 DAE, 8 equations

Usage

transistor (times = seq(0, 0.2, 0.001), yini = NULL, dyini = NULL,
            parms = list(), printmescd = TRUE, method = mebdfi,
            atol = 1e-6, rtol = 1e-6, maxsteps = 1e5, ...)

Value

A matrix of class deSolve with up to as many rows as elements in

times and as many columns as elements in yini, plus an additional column (the first) for the time value.

There will be one row for each element in times unless the solver returns with an unrecoverable error. If

yini has a names attribute, it will be used to label the columns of the output value.

Arguments

yini

the initial (state) values for the DE system. If y has a name attribute, the names will be used to label the output matrix.

dyini

the initial derivatives of the state variables of the DE system.

times

time sequence for which output is wanted; the first value of times must be the initial time.

parms

list of parameters that overrule the default parameter values

method

the solver to use

maxsteps

maximal number of steps per output interval taken by the solver

atol

absolute error tolerance, either a scalar or a vector, one value for each y.

rtol

relative error tolerance, either a scalar or a vector, one value for each y,

printmescd

if TRUE the mixed error significant digits computed using the reference solution at time 1e13 are printed

...

additional arguments passed to the solver .
