BodeHi there,

can anybody tell me why this code works..

restart: with(DynamicSystems): alias(delta = Dirac): alias(sigma = Heaviside): interface(imaginaryunit = j):
DGL := 2*(diff(x(t), t))+10*x(t) = 5*y(t):
sys1:=DiffEquation(DGL, inputvariable=[y(t)], outputvariable=[x(t)]):
BodePlot(sys1, thickness = 2);

and this code doesnt'

restart: with(DynamicSystems): alias(delta = Dirac): alias(sigma = Heaviside...
