Mathcad

Hi, all.  I have just started using Mathcad. The problem below is driving me crazy. Any idea why it is giving me the wrong output?  See below. I have also attached the Mathcad file. Incorrect answer:Correct output: RegardsCP  

If you click on License under Options in Prime, a host ID is also displayed. I was of the opinion that this is the MAC address, called 'primary' by PTC, for which the current license was generated.But apparently there is some confusion here and it is a constantly changing fantasy MAC!!? I can't believe that this is intentional behavior, which is why I classify it as a bug. I am not sure but i think that in older versions of Prime the correct MAC was shown, the one the license was created for. I recently had to generate a new license and had it created for the one that was displayed. Of course this license file did not work. This was quite annoying, as license management is not exactly one of the easiest features on the PTC support sites and it took me some time and effort to finally move the license to the correct MAC.  

Hi there, I have this plot which has ( x, y ) and A and B are points in this plot>>> I want to show this point in different colour and then draw the vector of them ABand then I have  another x and y ( x;cpt , y;cpt different values) I want to show point C,cpt in the same previous plot then draw the vector component of AB and C,cptthe result should look something like this:not necessarily the same ,but I need to show the vectors Thanks in advanceprime 9 

I have an input matrix from actual test data, where I have taken out 5 test dataset(Speed and 5 pressures), showing first line belowI now want to do some calculations, get all the differntial pressures for example : I know i can do like this: but it would be much nicer to display the result as a table with proper colum headers and units, how can i achieve this?  

I have data in excel and I want to copy that data and use as matrix in Mathcad prime ? Is this something possible how can I do that? Let's say I have 10 rows and 100 columns and want to copy paste it in matrix is there a simpler way? Due to the nature of data I am unable to share here if anyone has a sample data to show me how that can be done it would be great!

Hi There,I want to know the difference between the MathCAD and the Students version MathCAD.Thank you

I recently upgraded my c:/ drive and Mathcad no longer runs. It fails the license. I get a message "The license you have requested contains an error." When I run the .licensing setup wizard I get a server error of 403 Forbidden. It was working fine prior to the SSD upgrade. Please help!

I have Mathcad 9.0 but bought the Prime 10 Student edition. I'm trying to upgrade/activate the license. Do I need to uninstall the 9.0 and install the 10?Also I never received my product code. I received the payment confirmation email where it stated "You will receive detailed information on the delivery in a separate e-mail that was sent at the same time as this e-mail." However, I never received a separate email. I can't find a place to submit a ticket. The only place I can find for support requires a product code.

Hi I am new to Mathcad Prime and I'm trying to solve a kinematics problem, and I really need help. I want to multiply 3 nested arrays, but in step 4 I encountered the error "These arrays elements must be scalars. They cannot be vectors or matrices." I suspected it was because they are nested arrays, so I tried to convert the nested array H1 into a matrix with a code I found online and now I encountered the error "This value must be a vector,"Any help is appreciatedThank you

I have been using mathcad for many years, its been my go to software to help me think and sort out problems. Very recently I moved to Mathcad prime 3. I am unbelievably dissapointed. Yes it looks pretty , but its so hard to do anything. I wanted to display arrays as a picture , as I have done for many years. You cant do this. You have to save the data to a file, then read in the file in to a picture which has browsed a filename. then it does not update when you change the data in the file. Its awful and unusable in this application. I have had to revert to a pre prime version as this actually does what I need it to do. I cant believe we are on prime 3 and this is not sorted out.Help doesn't work either. Prime really is a backward step and I would not recommend it to anyone - are you listening PTC. I have colleagues who feel exactly the same. If anyone can suggest how to view 2D arrays as pictures in a usable way I would like to find out.

Hello everyone,in the attached file, the program should loop through length of dS and store the values in RA. could someone explain me, why the loop is not workingattached the Mathcad 10 file.

I am having trouble understanding why I can't get a solution using the defined variables but am able to get one when I put in a value for the variable.  My issue arises because the values X, Y and Z depend on Twall.  I want to be able to loop this with an update to Twall at each dt.  Any help would be appreciated. mathcad prime9 .    

I want to show a formula as a step for reverence, not have MaffCad try and solve it,Can't see how to do it, there must be a simple way to add a formula like a text box?

Hi could you help me to program this one?And the previous generated function works without m to (mod..).see the picture.  

The help document describe as follows: but i copy it into my MATHCAD, it shows like this: I am not sure if it is the issue of software version. The document is for V10.0, i am using V7.0 

I am encountering an error while configuring the trial license for Mathcad Prime 10.The error says: "... (-103) Cannot checkout an uncounted license within a Windows Terminal Services guest session."FYI, I am running the software locally (not remotely).

Let me tell you a story.  Once upon a time, perhaps even 10 minutes ago, when writing a new function (Bidiagonal) and testing it with strings, I replaced a direct function call argument with a predefined vector but forgot to remove the original function's argument.  After a few seconds of gazing at the (correct) output from Bidiagonal, I realised that the notation V(3) for vector V should have raised an error, but it didn't.    After a bit of playing with a new, blank worksheet, I confirmed that to get an array's elements, one can use the standard subscripted index notation Mi,j or the standard programming language parenthesis notation M(i,j). And Little Red Riding Hood and Peter campaigned for a better public understanding of wolves, their role in ecology, and their treatment.     I have a vague, dusty, indistinct memory of coming across this notation before, perhaps even on this forum, but I'm not sure - it might be a case of déjà vu.   Stuart

Hi thereI using (READEXCEL) but it read all the values as zeros they should be these  valuesIt works with the previous values thanks in advance

Need a licence to migrate to my new notebook

I am part of the Mott MacDonald IT team.We are in the process of transitioning to MathCAD Prime 10, as we have been informed that MathCAD 15 and MathCAD Prime 8 are reaching their end of life and will no longer be supported.Could you please provide more information on the support lifecycle of these products? This will help us proceed with the removal of the older versions of MathCAD and MathCAD Prime.Thank you.

Does anyone know of a more simple equation to derive the max moment of a simply supported beam. I have 12 equally spaced loads with the first and last being spaced further from the support than the typical spacing. Exterior loads are different from the interior. Heres some pictures of what im working with. The BMD diagram is my check for the moment of the HL93 Inv Loads. I've done this before when only working with a couple concentrated loads but the formula would be to long for this. Would also like to be able to check the moment at any location along the beam    

I wanted to install Mathcad Prime 4 to my new pc.The license manager accepted my product key but I can't chose the product for the license.

I just got a hold of MCP10 and started playing around with the new Advanced Controls. It appears that these controls are using Microsoft's Jscript version 5.8.  This is semi-equivalent to JavaScript/ES3 which is 11 versions behind the current version.  There are a lot of missing features that are commonly used in modern JavaScript, and I would like to at least upgrade to ES6. I was able to add the methods for working with JSON using this code in the TextBoxEvent_Start function to download and execute the json3 polyfill...   var xhr = new ActiveXObject("Msxml2.XMLHTTP"); xhr.onreadystatechange = function(){ if(xhr.readystate == 4){ eval(xhr.responseText) } } xhr.open("GET", "https://cdnjs.cloudflare.com/ajax/libs/json3/3.3.2/json3.min.js"); xhr.send();   Tangent: Yes, I know eval() is evil, and this opens me up to security risks if cloudflare ever starts sending me something malicious instead of the json3 polyfill.  If anyone h

I can't seem to get TextAlign to work to centre the text in the textbox.  Any suggestions?  Also for vertical alignment please 🙂 Is there any documentation with all the implemented properties for all the new control objects?  Thanks,
