Electrical circuit model for the transistor amplifier.
It is an index 1 DAE, 8 equations
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, ...)
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.
the initial (state) values for the DE system. If y
has a name attribute, the names will be used to label the output
matrix.
the initial derivatives of the state variables of the DE system.
time sequence for which output is wanted; the first
value of times
must be the initial time.
list of parameters that overrule the default parameter values
the solver to use
maximal number of steps per output interval taken by the solver
absolute error tolerance, either a scalar or a vector, one value for each y.
relative error tolerance, either a scalar or a vector, one value for each y,
if TRUE the mixed error significant digits computed using the reference solution at time 1e13 are printed
additional arguments passed to the solver .
