Dear, I have a dataset where the first column represents the index of a vector and column 2,3 and 4 the three possibilities. The first row contains the classification for a specific condition. The dataset has been manipulated to align these indices and classifications. My vector, for example, have this format:: However, I'm having trouble getting the vertical-horizontal lookup (VHLOOKUP) to search for each element in my vector and correctly return the value at the intersection based on the classification assigned to each vector element. Anything I tried returned 3x1. I have tried it all from the similar post:https://community.ptc.com/t5/Mathcad/Use-vlookup-over-a-vector/td-p/482509 Prime 9 attached. 

In the attached MathCad worksheet is an embedded excel file that has VBA apps in it.  It takes data input and calculates to values C and C` or is suppose to.  The excel file "CANDCPRIME.XLS" on its own works fine but once it is inserted in to MathCad it is being blocked by Microsoft as "untrusted".  What do I have to do to make it run inside MathCad.  It use to just fine but I haven't used this MathCad worksheet for a few years because my work did not include a lot of steel design.  I am using a subscription to Microsoft Office 365 and have tried to modify all the security and "Trusted" stuff I could find to allow this to run.  And ass I mentioned above by itself runs perfectly. Put all the files attached in the same location.Any help is appreciated.  Thank you,John

Hello,  I am using mathcad prime 10.0 and have created a program to solve for F_rated. I then want reference this program in a for loop, however it says the inputs to the function must be integers. Outside the for loop the equation works fine so I am a bit confused.

Hi, I have a MC15 calculation-sheet of 200 pages that have been converted to Mathcad Prime 9.0 that runs extremely slowly and which im now looking to optimize. Changes in input that in MC15 would have taken 5-10 seconds to recalculate can now take upwards of 5 minutes or more before the sheet is updated. I've been trying to read up on ways to speed up processing in Mathcad Prime and have read that size of matrices, the use of If-statements and possibly the use of "strings" in aforementioned matrices may be culprits. Which optimizations do you believe would bring me the biggest improvements in calculation speed as opposed to how MC15 was working? Does anyone have any recommendations how i should go about rewriting If-statements? (see attached picture of an example) Im going to see if i can break up the sheet in parts and work on a part separately. Then i can also upload said part here for you to partake in. Kind regards,Johan

We bought Mathcad earlier this year.  I believe we bought it in February.  I have a new computer and just went to install it.  I downloaded and installed Mathcad Prime 10.  When we pointed to our license server, it doesn't work -- we only get Express functionality.  My IT guys think I need to download Mathcad Prime 9 and that the problem is that our license doesn't support 10.  That surprised me because we only bought it a couple of months before the update, but the message seems to indicate that could be the problem.  See below: 8/15/2024 10:49:42 PM : The license request failed.Requesting MathcadPrime ...7788@XXXlicense003: (-21) License file does not support this version. If I need to download 9, how do I do that? Or do we need a new license file on our server to reflect the update and allow 10 to work? Thanks 

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?

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

As per the original post.    Hi: I have some old mathcad .mcd files. can you help me opening them and convert to mathcad 10. I am using a trial license only?  

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?
