Dear Team,We would like to proceed with renewing our licenses; however, we are currently unable to see any renewal options available in the portal.Could you please arrange for an account manager or sales representative to advise us on the renewal cost and provide a formal quote for one license?If any additional information is required from our side to process this request, please let us know.

  Hello, Everyone.  From :  So the question is : Is there a reason for : " max(  ) works and min(  ) doesn't " ?       Thanks in advance for your time and help.              Best Regards.

I work my business alone at home. I have a LAN with three computers which I use for backup purposes and Mathcad 14 installed. I'm the only individual operating Mathcad on this LAN. My laptop (one of the 3 computers) recently failed and required a new SSD hard drive. I've installed Mathcad 14 on this laptop but can't use it because of the license issue. I need to update this Laptop with a new license. The other 2 computers are older than 15 years, so they both will see a replacement in the near future. I assume their replacements will also need to be re-licensed. Please help me acquire one license that I can use now for the laptop and also for future replacement of the other 2 computers.

Hello everyone, I wanted to know if Mathcad 15 works and can run in a snapdragon laptop with ARM windows. 

How can I add conditional formatting to Mathcad sheet similar to what is available in excel?  I was envisioning formatting the output of a Boolean equation using Mathcad.   As near as I can tell, there is nothing in the Mathcad Prime 11 help that leads to some form of conditional formatting.

Hello Everyone.From : (view in My Videos) To :Solve , maximum of area of triangle_ACD ?Thanks in advance.Regards.

Hi, Having some challenges with advanced controls in Prime 10. I have attached the worksheet for reference. Would appreciate any suggestions or work around. Listbox height is not fully resizing with font size. Some white space is left when resized to minimum height. If text boxes are arranged vertically, the dashed line around selected textbox overlaps significantly on adjacent text box. Bit of context.. Recent reluctant mover from Mathcad 15 to Prime 10. We do a lot of team collaboration, so we used to use Mathcad 15 worksheets as templates letting the testers to access only input and output sections of the Mathcad worksheet to test the multiple product models before fine tuning them. so, it's critical to fit as many list boxes and text boxes in input section. We are trying this out in Prime 10 and seeing basic challenges compared to Legacy version.

I would like some help to develop a loop in Mathcad that returns x-axis offset distances between intersection points of two curves based on the y-values of the respective curves. The attached Mathcad Prime 11 file contains the details and a fuller explanation of this request for assistance.Note, this is a follow-on from an earlier post titled "Mathcad Intersections and Discretized MatrixData". A link to this earlier discussion has been included at the top of the attached file for convenience.

Haven't received the email with the download link even though i completed the form multiple times

Hello Everyone.From : How to simplify the above ? Thanks in advance. Regards.

I have old Mathcad 15 files that I need to convert to Mathcad Prime. Tried installing Matchad 15 but I can't find a download link. Is there any other way to achieve this?

Was using free trial and then my school put their license on my computer and now all my documents I was using on the free trial say file not supported. Need files urgently for deadline

A challenge from Facebook, and one of the (wrong) answers.   My solution is in the closed area.  Have some fun.

I would like some help to develop a loop in Mathcad that appends each intersection point between a piecewise linear curve and a set of straight lines, to the piecewise linear curve matrix. The attached Mathcad Prime 11 file contains the details and a fuller explanation of this request for assistance. 

I started my college years using Mathcad 11, and I still use it after two decades. And for many reasons: I know its plus and minus points (more plus than minus).Once upon a time, I could integrate it with Excel and other software.It is reliable overall: no crashes or file corruption.It saves space and memory: in 100Mb of HDD and a few dozen Mb of RAM, it does what other mammoth software (including the following versions of Mathcad, not to speak of Mathcad Prime) do.I always kept an eye on the PTC community to look at the reactions to Mathcad Prime's evolution. I think I am not alone in still using the Classic Mathcad (if not v.11, it will be v.15).  I am interested mainly in Calculus (so symbolic math solutions), Matrix Algebra Simulations, and a few Statistics. At the same time, I am not interested in integrating Mathcad to other PTC software.Is it worth moving to (or trying) Mathcad Prime v.10? Given the above interests, how is it compared to t

On one particular calculation, I get a red box"System Error: Item has already been added. Key in dictionary: "Key being added: " Anybody have any insight?

I've been using MathCAD Express 10.0.1.0 version now and tried to upgrade the software to version 11 yesterday. Tried to fill out the free trial form but never receive the download link even after a day. Could I get help how to upgrade the software but still stick to the free Express version?

I've been doing a bit of revamping my Mathcad Express worksheets to Mathcad Express 11.  As part of this activity, I've updated my library of timing functions to reflect the way I've been using them.    For example, timer1(f,a) used to return both f(a) and the time it took to evaluate f(a); now, it just returns the time taken, whilst timer1n(n,f,a) executes f(a) n times.   For those of you with prior versions of Mathcad, here are the timing function definitions:     Here is a good example of how writing recursive algorithms should be done with care, fib vs Fib.     And here's a graph showing just how much worse the difference in Fib's performance gets as its input argument n increases.     The timing functions are in the first Area in the attached Mathcad Express 11 worksheet (to make it easier to copy them to another worksheet or include them in a template).   The utility of such functions is also evinced in:   https://com

Hello Assuming you have a matrix defined, is it at all possible to use (part of) this matrix to create the choices available in a "Basic combo box"?More explanation:I use READEXCEL to read a table from an Excel file, and get a matrix with column headers in the first row, and some other identifier in the first column. Can I put this matrix into a combo box, so that the user can select the relevant row for further calculations?RegardsHallvard

How can I download the trial version of Mathcad Express? Im a University student, trying to download the program for one of my classes, but nothing happens after entering my data on this website: https://www.mathcad.com/en/try-and-buy/mathcad-express-free-download

Hello to everyone, I have a new laptop where I have already installed Mathcad Prime 11.00, but some of my old Mathcad 15 files still do not work well in Mathcad Prime when I convert them.I still have the Mathcad 15 package saved in my cloud, but I don't know how to make it work. What should I do to make it to work? regards,  Rogelio

My classmate registered for MathCad (trial subscription) but did not receive any emails from PTC/MathCad. Our professor insists that we use MathCad, but he cannot do homework because his registration never went through. Please advise.

My string library defines three different representations of a string, two of which should already be familar: the string and the vector of character codes. The third type is the vector of characters.   In the following, "str" indicates a string, "vec" indicates a vector of character codes, and "chr" represents a vector of characters. For example, chr2str indicates a conversion from a string to a vector of characters.   chr2str itself is relatively quick, even for long strings. chr2str0 has the limitation of hitting Mathcad's recursion depth limit. chr2str2's use of folding over concat, however, is proving somewhat slow once the string length increases to above about 20,000.   The challenge is to define a faster recursive variant of chr2str.     Where the dependencies are as shown below (except the timer functions, which are in an Area at the top of the attached Mathcad Express 11 worksheet).     Stuart

I'm using MathCAD 9.0.0.0. I laid our 2 sets of 3 equations. One set is using variables. The other set has the values plugged straight in. The set with the variables should equal the set with the values because the values are the same, but they don't and none of them equal the correct answer. What should happen is...Rx=Rx=-22Ry=Ry=211.5R=r=213My MathCAD program is written to follow this example...This is how my MathCAD program looks...Ignore the 25 degrees and the 75 degrees in the diagram. This is a homework problem altered to match the example problem so I can test to make sure it works before plugging in the values for the homework problem. Also, I'm interested in fixing the "values" problems Rx, Ry, and r. I only created those to figure out why my variable problems Rx, Ry, and R aren't working. Attached is my program. Thanks,    Brent
