Hi David Many thanks for the examples. Thanks to one of them, I wrote an animation that works in this case. Manipulate[ tfm = TransferFunctionModel[k 1/(s (s + 1)^2 + k), s]; out = OutputResponse[tfm /. k -> kval, UnitStep[t],...
Hi Marco Thank you very for the answer but unfortunately I could not figure out how to adapt your code to my problem. If it is not asking too much, I am sending below the set of equations for you to see. Noise needs to be added to the first,...
Neil, Many thanks. It worked but I have to say that it took more than a couple of attempts. I remember having the same problem a few years ago. It seems that despite Mathematica new versions, the problem persists. Regards Ed
Many thanks. I completely forgot about RegionPlot.
Many thanks. I can see the difference.
I forgot to mention that what I needed it is the opposite of the outcome of the commands above but thanks to your answer I have one solution at least Select[Subsets[Table[Subscript[\[Theta], i], {i, 5}]], MemberQ[#, Subscript[\[Theta],...
Thank you all ever so much.
Hello In the past I had not problem to link a R distribution (already installed on my mac) to Mathematica (now 10.3.1.0) using RLink. However, after upgrading R to MRO 3.2.4, the InstallR no longer works. The commands I have used are ...
Hi Michael The problem is that a, b and t are not available. However the Transpose did the job. a = {xa[[All, 1]], Log@Abs[xa[[All, 2]] - xb[[All, 2]]]} // Transpose; Many thanks. Regards, Ed
