Mathcad

Just downloaded the free trial of PTC Mathcad 4.The tutorial asks to download the "data_files..zip" file.I can't find it on the PTC web page.Can anyone tell where/how I can find and download the data fiel?Thanks,

Hello , the problem is that because i have mathcad prime 4.0 but the problem is that i dont have the converter. So i need is someone could convert for me please. I have a test and i need that file. The format is in xmcd and i need it on mcdx. Thanks !

HI,Please help. What is wrong with this.  I am expecting to have a multiple array in the result .

I am currently using Prime 3.1 to solve a simple equation as given in my mathcad sheet.My defined equation works to return correct values with the correct units. However using it to solve the equation for a single variable returns that there are no solutions.Yet I should be able to get back a solution around 950 (verified by graphing in excel).I am not too used to using this solve function in prime as usually I'd use the solve in Mathcad 15. Can someone more experienced just double check to see f I am doing anything incorrect ?

G'day,There seems to be a bug in Mathcad 4.0 where it just loses pagination and things creep above the page break line.I've spent about an hour trying to fix a many page document only to hit save and they randomly creep up again.Is there a solution for this?Thanks,Wade

Did we already discuss that kind of bug here?And has anybody an idea what the reason for this strange errror (recursive definition) could be?The error occurs when the frequency is negative and floating point,

Hello guys, I have a few question about general functions of MathCAD:1. I found that when using Excel Component, the whole length of Excel table has a specific upper-bound (about 1.5 times of an A4 page). If I extend the length size over this limit, the words in the cells will be deformed and the displaying rows may not increase. This issue makes me unable to show a length Excel table in once, I have to separate the table to multiple Excel components.2. How can I access the page number and chapter title to automatically generate a table content like in MS Word?3. The height of Header and Footer are fixed, I can't add more tables/pictures/words under the default height.Are there any solution about these issues?Thanks!!

I have one Mathcad worksheet for interpolation.  It works fine on a set of sparse data in the DATA 1.xls file, but the interpolation fails for the more dense data in the DATA 2.xls file.  I don't think I have any duplicate data points; however, it indicates that one of the arrays in the interpolation is not in ascending order for the more dense data.  I cannot find any errors in the data.  Here is an image of the error message.  The two Mathcad 15 worksheets are attached along with the data files (one for each Mathcad sheet): one for the sparse data and one for the more dense data that produces an error.  I don't understand why it works for one set of data and not the other when the only difference is the number of data points.  Any suggestions.

HiHow can I select the maximum number  in each column from (m) but  not more than 1  and match this in the "match ?

msxml6.dll is either not designed to run in windows or it contains an error.what does this error mean, how can it be resolved ???

I've just started using MathCad, and I do not know why the variable is undefined (its probably some silly error, but its been frustrating me for a while now).Any help would be immensly appreciated.ex :5x+10=20find(x) "arrow"

Mathvad PM has a spellchecker but better as in MS Ofice!

Hi!Maybe today it is much too hot and I have drunk too little water and coffee, but i can't find a stable solution for a defined problem:I have to solve a mechanical problem (dimensioning steel cables) with the solve block including 18 equations with 18 unknowns:It is required that the length change, the number of threads and all forces, etc. are calculated with the solver.Please see the sketch (you can doubleclick the .exe file to view it, it's an e-drawing file) and worksheet in attach.The Problem is: I have as many equations as unknowns and when i change the guess values, i get always different results.Are my equations right, and do i define something double or contradictory?Any help will be appreciated.Thank you very much for your efforts.Volker

Transfer of Mathcad LicenseHello guys,Im Petterson F. de Oliveira from Brazil, IT Analyst working at Akaer Engenharia.I need some help about this case, im working at a company that bought assets of other company including softwares.I did some transfers of other softwares and that company signed donation letter to us and we transfered and now we are using normaly.Now its time of license of Mathcad, we have 10 floating licenses and 4 local licenses to transfer and we are need it to start some projects works.I sent e-mail to - but i havent any answer, I called to Sales Office at Sao Paulo and I havent answer, nobody answer the call ! I sent chat message to PTC Facebookand they indicated this community to ask help.Can someone help me?Thanks.Best Regards.

Dear Community:I am a very new user of MathCad, and I need help understanding the syntax of the linfit function.  (At least I think it's a syntax issue).I built a small worksheet to look at various curve fitting functions (it grew out of a need from a work related worksheet; I have hand entered some of the data and changed to units to make the example sheet self-contained).  I successfully parroted the linfit example for a quadratic fit (a*x^2+b*x+c), but I could not extend it successfully for a cubic fit (a*x^3+b*x^2+cx+d).  I could successfully build a cubic fit using polyc.I enclose the worksheet:Page 1: DataPage 2: Cubic SplinePage 3: Straight Line Page 4: Quadratic linfit (and polyc)Page 6: Cubic linfit (and polyc)         <---- This is where it goes wrongAny insights would be appreciated.Regards,Bob

Hello! I have a 2 graphs. I don't know how to calculate the area under the graph. Graph with red is half of a circle, and graph with black is defined by 3 functions. Normally, the graph area with red is higher than the graph area with black. Thank you for help!

Hi all!Maybe I'm losing in a glass of water, but I can not solve the second differential equation with odesolve, in the problem hereunder exposed. What's wrong?

In Mathcad15 , the solution of the following simulataneous equation is  correct ?Because the solution of MM,NN,LLKs is zero. If so, zero division is in equation.One solution is also attached.Please advise me.<< one solution of above equation>>

Hi, I seem to have worn the internet thin, and have scoured posts here aswell and have not found what i'm looking for. i might have misset it, if so i apologice. Also, please excuse my english.  So what i'm looking for is a way to have mathcad prime look at an equation and store coefficients as variables - maybe by comparing the equation to a "mask". please take a look at the attached file to see what i'm talking about. Thank you in advance /Tonni

No idea why this doesn't work.Even though this works as intended:So it works for substituting B1 for D1 and F1 just fine, but for some reason substituting B1 for whatever it is defined doesn't work.Thanks in advance.

I run Mathcad 15 on a virtual Windows XP machine within my iMac Sierra. I have not used Mathcad for more than a month. when I came to use it this afternoon (9th June 2017) I could not start it up. Can anyone direct me to someone who might be able to help, e.g. a help department of PTC, please?

Hi,I need help regarding a user input method. I'm creating and programming a list of calculations derived from a materials properties, such as Yield Strength, UTS and Young's Modulus, and I'm wanting to include a function where the user can select their choice of material, rather than typing it in manually, such as a drop down list or a tick box system. I'm currently using prime 3.1, but have the option to upgrade to prime 4.0. Could anyone assist me?Thanks

Hi all, I have a question regarding the selection of a proper value for a parameter from a list based on the evaluation of its transfer function. As shown here, if I have a variable a, whose value can be selected from a list. A transfer function TF(s,a) is an s-domain function including this variable. We can calculate bandwidth and phase margin of a selected value of "a". I am wondering if it is possible to specify the criteria for the bandwidth and phase margin, and let Mathcad follows these criteria and select the optimized value of "a" from the list?Thank you!
