How do you clear the contents of the trace window?

Using a Given ... Maximize(f,x) solve block.  The equations work correctly for a test case.I'm re-writing the worksheet to process a table of inputs I'm reading from Excel.  So I need to run the solve block to find the maximum "x" for each row of the Excel data (e.g. 1000 times).  I've decomposed the input table into several arrays and have done a bunch of calculations on each "row" using range variables or "vectorize" operator.What's giving me problems is that the function f has more variables - f(a,b,c,x).  So for each "row", a, b, and c are fixed, and I need to find x that maximizes f.  The next row, a, b, and c are different, but they are considered as fixed values for the purposes of finding a new x that maximizes f.I made an example in Mathcad 15.  Oddly enough, the simple example I made works.  But if I add units, the solve block fails.  Even stranger, the original worksheet with a single case used units and the solve block worked.Looking

I apologize if this has been asked before as it would seem something others would have asked but my search of the blog returned nothing. In the attached file I have a simple 2nd order linear DE. I can see to extract individual values from the Odesolve output. I've also figured out how to extract the response to a vector. My question is how to know I've captured all the important content from the Odesolve output with my selected time increment of .01s. What if I was looking for the exact maximum. Seems like with my approach I'm only getting an approximation of the Odesolve output.

  Electrical engineers may not pay much attention to the Driving Engine of the generator, theymight say this is a mechanical problem. The heat of the returned fuel oil from the enginemust be dissipated using, either a Day Tank or a fuel cooler. This is very important to keepthe supply fuel temperature within a specified limits for optimum engine life and maximumpower capability. However, the electrical engineer might need to know the following in a timeperiod of 12 Hrs of operation (for example), or 720 minutes (incremental time period equal 60mins) :1- The Tank Fuel Quantity in Lb.2- Tank Capacity in %.3- Mixture Temperature (Tmix-deg.F) of the returned fuel and the fuel in the tank.4- Fuel Height in the Tank ft.5- Heat Rejection to/from the Day Tank Btu.6- Temperature Change in the Day Tank deg.F.7- Day Tank Temperature deg.F.

Hi all,I am trying to use a special symbol in a variable name. To do this I have tried using the special symbol function  by pressing ctr - shift - k and then typing the symbol I would like to use. This works however I seem to keep getting an error message when I try assign a value.For example I wish to do the following:I have tried both equal operators but none seem to do the trick. Any help on how I can achieve this would be greatly appreciated. I am using MathCad 15 but also have access to MathCad Prime as well so I am keen for any solution that will work.Cheers,Liam

Hello,when I look to the learning Programm, I can not see the figures in it. A screenshot is seen below. Can you please help me?

Is there any way to remove green brackets by text editing in a XMCD file (XML)?Maybe is something I can replace/change as text and after that I perform a save in Mathcad 15.Tkanks

I just downloaded Mathcad prime but status is shown update from M030.... Can you explain what this means?

Hi...As I want to assign variable values as per condition in Mathcad which have to continue for next calculation, I will explain detail by following example.As per Above example, I have assign values for variable ss, pp and Shaft_Type, So I have different values if my Shaft_Type is 1 or 2 ( Shaft_Type value will comes from Creo).and same values will be applicable to my rest of calculation i.e. if my Shaft_Type is 1 , ss=4 and pp=10, and if my Shaft_Type is 2. ss=5 and pp=12. and later on I want to do calculation by taking these ss and pp vaules.So please can you help me.Thanks,Prashant Pandarkar

Hello PTC community,I have recently been introduced to Mathcad 15, and understanding all the benefits of it, I got stacked in my first attempt of doing something. I have a simple excel file (attached also), which I wanted to use as a training on Matchad, translating the content. What i encounter is a conceptual problem. I have literally no clue how to approach those simple calculation in Matchad. Can you please give me a hand in what will be the best approach?I guess this is a typical issue for beginners, but I could not find in the helps files info about such a problem (maybe neither used to this PTC community website). Excuse me for maybe making too obvious questions. Thanks a lot in advance for all your help.

Hi,At our division at work we use Mathcad-15 for writing our technical reports and saving them to PDF. Then we print the PDFs to store in a physical archive.For archiving purposes every report contains the file path to allow someone to find the digital version of the report even on a printed copy.It looks something like this:"The digital copy of this report can be found here:"\\disk1\folder\subfolder\report.xmcdWe are now moving our digital copies to a new disk, let's call it "disk2".Hence, we need to change the files paths in all the reports to:\\disk2\folder\subfolder\report.xmcdWe also need to save all reports to PDF, after the file path has been updated.Since we have some 500 reports to update my question is if this is scriptable? Both changing the file path and saving as PDF.If so, can someone support us on how to do it?Best regards,Oskar

Hi ALL,i have a mathCAD sheet, in which a area is locked by other user and not visible for edit and review. Kindly help me to unlock the same.for Excel, VB number of unlock swares are available. is thr any software in same kind to so for MathCAD.?? Thanks,Vasanth.

I am still using MC v.11.x.From a matrix I needed to extract the eigenvalues and eigenvectors, and re-order them (starting from the eigenvalues) in a decreasing manner. Accordingly I needed to change column order to the eigenvectors, so they correspond to the new order of the eigenvalues. I used the function eigenvec(M,z) for this. Yet without success.The Figure I hope explains the problem, in its essence (there is no re-ordering here). It shows that the connected eigenvector to its eigenvalue (captured with "eigenvec" function), is not the same of the one that appears in the function "eigenvecs(M)".I understand (or  to say better, I realized, see the Figure) that the same eigenvalue may have multiple eigenvectors. But now:     1. How can I extract the same eigenvector that appers in the "eigenvecs" function, by recalling its own eigenvalue?     2. And more in general, is there a way to see the multiplicity of eigenvectors connected to a giv

Hello,today i've tried to install Mathcad Prime Releases 3.0 and 3.1 under a new Installation of Microsoft Windows 10 Professional x64. Both of them failed. Does someone know more about possible reasons for that Problem. Or is there already a Workaround for this problem?Kind regards, J. Dessecker

I like use Mathcad 15, and I know it will compatible with the Win8.1 and will be released this year. Does anyone know any information about the Mathcad 15 M040 releasing?

If I use Mathcad 15, I can define a variable such as "a:= .7 in"  if I write this exact same thing in MathCad prime it will result in an error.  I have to write "a:= 7 in" then come back and add the decimal place after it's accepted 7 inches.  What am I doing wrong? This seems absurd and is incredibly frustrating.

A little bit of experimentation shows that this effect occurs with a number of characters that have math representations (eg, / and +).  Is this a known problem?Stuart

I've searched the other threads and most of them contain something about being on "maintenance", I don't really understand what that is or if I have access to it.  I've tried upgrading my account but it was not sucessful.  Basically I will soon lose access to the computer that I installed Prime 3.1 student license on and will have a work computer that I want to install it on.  How do I do that?
