Fitting multiple data sets to multiple functions with shared fit parameters 1 9 (1/7/2013 5:35:58 AM) comp.soft-sys.math.mathematica I am a an experienced user of Mathematica and am used to fitting complex valued functions to data sets, but only one function at a time. I am attempting to determine the parameters in a model of a physical sys... dr

More Button crashes 1 16 (10/18/2012 7:08:53 AM) comp.soft-sys.math.mathematica All, Yesterday I posted an intermittent problem I was having related to Button use. I have now found another Button problem that is repeatable. I was not looking for it; it found me. >> This example can ... dr

Nonlinear curve fit as a Button function fails quietly 2 8 (10/17/2012 2:50:41 AM) comp.soft-sys.math.mathematica All, I apologize in advance for the complexity of the code I will paste below. I tried to simplify it as much as possible, but if I simplify it too much it does not replicate the problem. I am building a M... dr

How to lock down a Dynamic object in a report 2 32 (9/29/2012 7:09:59 AM) comp.soft-sys.math.mathematica Is there a way to lock a Dynamic object so it does not respond to users? I know it sounds funny, but I have created a LocatorPane to organize items in a database. When I publish my weekly report as a CDF, the ... dr

Continued fraction from rational polynomial? 0 19 (6/23/2012 8:24:09 AM) comp.soft-sys.math.mathematica Does Mathematica have a function to develop a continued fraction from a rational polynomial? I have managed to implement the Euclidian Algorithm for polynomials as below: PolynomialContinuedFraction[a_, b_,... dr

Converting an imported STL into a solid Region for integration? 0 25 (5/26/2012 9:13:44 AM) comp.soft-sys.math.mathematica I am trying to compute the center of gravity and mass moments of Pro/E solid models I have imported as STL's. Once in Mathematica, the models are polygons that define the surfaces of the objects. Does anyone ... dr

GraphUnion that keeps Properties intact? 0 19 (4/13/2012 8:54:47 AM) comp.soft-sys.math.mathematica Is there a way to make GraphUnion merge two graphs with the Properties I have set in the individual graphs intact? The default behavior appears to be to strip off all the options I have set for the vertices an... dr

how can one use mathematica get the approximate derivative of {x,y} data points? #2 1 30 (1/16/2012 12:03:52 PM) comp.soft-sys.math.mathematica The derivative curve you will get with Interpolation[]' can look very weird. I find I get better results using Interpolation[..., Method->"Spline"]'. The Spline function is continuous in first and second deriva... dr

Re: Warning: OS X Lion and compilation 0 32 (7/22/2011 1:11:53 AM) comp.soft-sys.math.mathematica Ok, I won't call it a total false alarm. I had Xcode 4.0 installed prior to installing Lion, and the scenario I described in my previous posting occured. At that time, I also tried typing "gcc" in the Termina... dr

Warning: OS X Lion and compilation 1 31 (7/21/2011 9:49:04 AM) comp.soft-sys.math.mathematica I have not dug thoroughly into this yet, but I wanted to get the warning out quickly. Apparently, OS X Lion does not include the gcc compiler. I upgraded to Lion this morning, then on a lark tried to compile ... dr

Creating a PDF graphic with Mathematica 4 21 (6/27/2012 8:13:12 AM) comp.soft-sys.math.mathematica Hello, I created a PDF graphic that contains one character (the letter A ) from the TeX Gyre Chorus font. I created the graphic using Mathematica 8.0.4. Then I included the PDF graphic in a LaTeX docum... rm.tech (10)

Simplify and then discretize a set of equations with derivatives and integrals 1 28 (5/29/2012 9:45:39 AM) comp.soft-sys.math.mathematica Hi, I'm new to Mathematica, but as I professionally have access to it, I'd like to use it to simplify this problem. I have a set of equations (from http://www.simulanalog.org/statevariable.pdf) explaini... matthieu.brucher (13)

SystemModeler Users? 4 34 (12/21/2012 10:37:50 AM) comp.soft-sys.math.mathematica Hi, I bought SystemModeler a while back. I am wondering whether there are SystemModeler users on this general list? I have some questions about how to convert a Berkeley Madonna model to SystemModeler. Whe... comer.duncan (4)

Terrible unit trouble in Mathematic 9 7 19 (12/18/2012 7:35:32 AM) comp.soft-sys.math.mathematica I continue to receive "Unable to interpret unit specification m/s" (for example, but almost anything I attempt returns this message) with input: UnitConvert[55 mi/h,"m/s"] or UnitConvert[55 mi/h,m/s] or any ot... tio540s1 (4)
