attach y2 to y1

[feldmaus]

Hi All,

i want to attach the result of the discharge function u2 to the result of a
charge function u1 , so how to do that?

T=1e-6
t1=0:0.1e-6:1e-6;
t2=1e-6:0.1e-6:3e-6;
U0=1
u1=U0*(1-exp(-t1/T))
u2=U0*exp(-t2*T)

i do not want to plot to function on one figure.
After this i want to make the fft of u.

Any hints

regards Markus
