If I have the two equations y=a*x and x=u-y where y is the output and u is the input, how can I get Mathematica to combine these two equations to get the single equation, y = (a/(1+a))*u? Thanks.
Hello, I'm trying to replace the complex coefficients with their real parts in a rational function. So, these coefficients are nested sort of deep in the function. So if the function is, say, dtf, then I'd say something like ...
Hello, I'm working on extracting parts of a filter model and things aren't working as expected. I've attached the workbook. First on line 2 I've created a filter model which takes the form of a Transfer Model. Then on line three I extracted the...
Hello, Does anyone know of any way to generate a continued fraction from a Filter Model? Thanks.
I have a model in which I'm testing my new white noise block. After building the model I successfully validated the model. I then clicked the simulate button and got what looks like a host of compile errors. I don't remember ever getting these...
Is it possible to define one's own Head or type in Mathematica? If so then how does one do it? Thank you.
Hello, The function base^^ (example 16^^1A2C or 2^^10112) always frustrates me because it seems to be a convenient function and it is a part of Mathematica but doesn't behave like other functions. For example Map[(16^^#)&, {A, B, D, F}] doesn't...
Why doesn't this work in Mathematica, cu[x_] := BaseForm[2^^x, 16] ?
In a Mathematica notebook, I execute the following lines,Needs["GUIKit`"]; GUIRun[Widget["FileDialog"]];What looks like a standard File Dialog window appears.  Using the dialog, I select a file and then click the "Open" button and...
