Hello,
I make an calculation of an antenna circuit. For this I have to use the step function. When I want to
make the inverselaplace function to my equation, it will not be work.
I think this will not be work, because I think that matcad will calculate values from t<0. But I want to
analyse only values which are t >= 0.
Can I give mathcad the information, that it calculate only with values t>0
Please look to the matcad file, where I have made also a lot of comments on page 4.
The pages before is normally not relevant for you.
Thanks a lot
Regards
Roger
Solved! Go to Solution.
Hello Alvaro,
I have openend your mathcad file and I can see that you have created an graph, but I don't see an curve.
Also the invlaplace
current_1(s):=CURRENT_1(s) invlaplace, s
ist colored in red.
Is it working at your home ?
I use mathcad 14

I use mathcad 14
which version of 14?
Mathcad 14.0 M020 (14.0.2.5)
There have been lots of problems with Laplace transforms in MC14. I guess this is one where it's broken in M020, but they have since fixed it.
At work, in mc15, the image of the answer. There are a lot of problems with laplace and invlaplace with mupad.
Regards. Alvaro.
Can I give mathcad some help ( t>=0 ), that he can calculate it.
Or can I split the function, that it would be easier to calculate it for
mathcad.
