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... |
