depVar0, VarStep [, eulerStep]) ⇒ matrix

VarStep [, eulerStep]) ⇒ matrix
euler(ListOfExpr, Var, ListOfDepVars,
{Var0, VarMax},ListOfDepVars0,
VarStep [, eulerStep]) ⇒ matrix
Uses the Euler method to solve the system
with depVar(Var0)=depVar0 on the
interval [Var0,VarMax]. Returns a matrix
whose first row defines the Var output
values and whose second row defines the
value of the first solution component at the
corresponding Var values, and so on.
Expr is the right-hand side that defines the
ordinary differential equation (ODE).
SystemOfExpr is the system of right-hand
sides that define the system of ODEs
(corresponds to order of dependent
variables in ListOfDepVars).
Differential equation:
y'=0.001*y*(100-y) andy(0)=10
