Mathcad

when i do some multi-objective parameter optimization cases in mathcad,i find that there are only three algorithms that can be used，L-M，Conjugate gradient method and Quasi-Newton method. these methods may can't find the global optimum,or take very long time.nowadays,there are many other algorithms,such as GA(Genetic Algorithm),it may solve these problems easily.but my mathematics is poor，can any body do it,or has anybody done that?i want to have a try,but my methematics is poor,at the same time,i am not proficient in programming.wish for your help.

Upgrade to 14.0Originally in 2019 I still installed the 64-bit version.My Mathcad stopped working after installing Windows 11.Mathcad 14.0 is an outdated version (2014) and, it seems, can no longer be recorded using today's licensing process.Please send me a valid license file.dat.Kind regards,Beat Eichenbergerbeat.eichenbgr@bluewin.ch---------------------------------------------Translated text from German to English using google translateSubject - Lizenz ProblemBody - Upgrade auf 14.0 Ursprünglich 2019 habe ich noch die 64bit Version installiert. Mein Mathcad funktionierte nach der Installation von Windows 11 nicht mehr. Mathcad 14.0 ist eine veraltete Version (2014), und ist, wie es scheint, mit dem heutigen Lizenzverfahren nicht mehr erfassbar. Senden Sie mir bitte eine gültige Lizenzdatei.dat. Freundliche Grüsse, Beat Eichenberger beat.eichenbgr@bluewin.ch - By Community Moderation Team--------------------------------------------- 

 

Hi,I am attempting to create a program that will autogenerate several MathCAD file templates based on variables that will be taken from an excel sheet that contains a list of parts.  I am using MathCAD Prime 9.0 Some things I've looked into are using the API or changing the XML data directly.  The API doesn't seem to support a way to add in new inputs and outputs to a blank worksheet. Changing the XML data directly seems like it could be a good option. From other posts I've read it sounds like you can change the file extension to a zip, unzip the file, change some data in one of the files, then rezip and change the extension back. However when I have tried this the process of unzipping and rezipping changes how it is compressed which causes it to be unreadable by mathcad, even if I don't change any of the internal files. Is there a way I can inputs and outputs to a blank worksheet with the API that I am missing? Is there a way to unzip and rezip the m

Hi Guys,   I tried to enhance mathcad Prime's page counter as the counter does not allow starting with a page number other than 1. So I'm using a textbox as a page counter. In this textbox I have an input and an output. The counter shall increase by one on each consecutive page making it possible to combine several files into one. Or so I thought. For some reason I can't hide or collapse the left side of the textbox which makes it appear ungainly. I've tried to hide it and to collapse it. To no avail.   Does anybody have an idea what I'm doing wrong? Raiko P.S. I'd prefer to have this textbox in the footer, but prime does not accept it. Any idea how to change this?

Hi,How can I draw the ASYMPTOTIC bode plot of this function in more automatical way? Is it possible? I mean I know that this asymptotic bode plot can be draw after some manual analysis, but is it possible to make a program that can draw automatically this thing?   I am expecting something like that (red plot):

Hello, everyone. I am trying to install a floating license server and it worked. However when performing some tests with my colleagues I realized that after I borrowed the license, I was not able to return back for another colleague to pick.I received the following error msg: "Unable to return the license. Verify that the current license settings are correct.". I found nothing about such error on the online documentation.Did someone experienced the same issue? Thanks in advance for the feedback. GF

Hi PTC Community, I'm currently facing an issue while converting files from MathCAD 15 to Prime 9. It appears that a specific checkbox option, which was available in MathCAD 15, is missing or not functioning correctly in Prime 9. I'm trying to manually debug the issue, but I'm struggling to find a solution. Has anyone encountered a similar problem or know of any workarounds to restore this functionality in Prime 9? Any insights or advice would be greatly appreciated! Thanks in advance for your help!

I am using Mathcad Prime Release 6.0 and Datecode6.0.0.0Dear all, good afternoon from Brazil. I hope you are well. Since our Mathcad´s Brazil support team did not solve our issue, which is a big problem for us, we are contacting PTC directly. We have 7 Mathcad M15 M045 licenses (one of which is a network license) acquired by General Electric in recent years. In the last few weeks, we bought one more standalone license, but it is for PTC Mathcad Prime 6, because it is no longer possible to buy an M15 license. Our problem is that the Prime version does not directly open the M15 files of our current version. To do this, we were instructed to do a conversion from the old format of the file to the new format. But here is the problem: after this conversion, a lot of information, formatting and macros are lost from our worksheets and the calculation is not done directly without first solving some problems. So that you understand the seriousness of this problem: we have more than 200 folders,

hello everyone,i am trying to get 'z' as matrix as shown in the attached Mathcad 10 sheet.i do not know where it is going wrongcould someone help me here

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0When using the new Advanced Controls features, performance suffers greatly. This would be expected if I were loading in large amounts of data or perhaps performing complex processing with these regions, but all I'm doing right now is using text boxes to display results with color coding or select which version of text to display from a known list. Literally just display boxes, and yet performance suffers greatly. It was never this bad using essentially the exact same files before adding the advanced controls. M, colleague has even worse issues, where the advanced controls grey-out as if they're still processing, or unable to finish processing, and is unable to get them to cooperate again. Is there some performance issues with the advanced controls? Is there some trick we can use to reduce the performance demands?Has anyone else experienced something like this?-Sean

Today, when I tried to open mathcad, nothing happens, not even the splash screen shows up. When I open task manager, I can see that the mathcad process starts for a few seconds and then it's gone. Already tried searching the community for similar cases but I didn't find anything that works. Please help me! I'm just getting in love with the productivity enhancement I get from mathcad! Further info: no error messages appear, doesn't work when I try to run as admin, or when I restart my pc

Gentlemen, please don't take this as impudence, but could you tell me how to make sure that the paths don't cross?

I could be doing something wrong here, but it seems that I see an inconsistency in the substitution function in the symbolic math in Mathcad Prime 10. I started with: The result here in incorrect in that the first term (se^2*Vc*t^2) should be divided by 2.If I do the same integral without using the substitute function as follows:Here we arrived at the correct answer.  It seems possible to me that it might have something to do with the limits of integration.  I tried using a top limit that was not the same as the integration variable and it did not make any difference.I will be really grateful for anyone's perspective here especially if you see that I am incorrectly using the function.

Hi, attached file (build by Terry Hendicott) creates a 13xYYY matrice from an 13x3 indata matrice. It calculates the inverted product of each column in the 13xYYY matrice and plots it in the diagram. Now I would like to extract those columns with a product between two values (Here it is 15 and 25 millions)  Then I would like to present those columns in a new matrice like   

Hi, Can I get some help how to how to write a function that return all row products in a matrice according example below?  Second question is how I extract data lower, between or higher then a given number.
