nand: Nand Gate, Index 1 IDE

Description

It is an index 1 IDE, 14 equations

Usage

nand  (times = 0:80, 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; only mebdfi available for now
maxsteps: maximal number of steps per output interval taken by the solver
rtol: relative error tolerance, either a scalar or a vector, one value for each y,
atol: absolute 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 417600 are printed
...: additional arguments passed to the solver .
