Mathcad

Hello everyone!I have a big problem with MatCAD and my Laptop.When I try to print (both Adobe PDF printer and my home printer), MathCAD print an empty spreadsheets with only the logo on the headers and the ruled. Nothing else: no formula, no text I wrote.Attached you can find an example.I use a MacBook Pro 13'' (last gen) with Bootcamp and Windows7.I have tried printing the same files with other PC and all is ok.Could anybody help me? Thankyou!Carlo

Hello, Everyone. Meaning of _z1 ? Thanks in advance for your time and help. Regards.

Hi,I have a function that is defined by different equations, based on an "if" statement. both the equations and the conditions depend on coefficients stored in vectors. I expect, as a result, a function that returns a vector. I have tried several syntaxes, but I can't find one that works. Either i don't put the index, and the condition fails (comparing a scalar to a vector), or I put the index and the function fails to find a result (although, if I set the function parameter as a fixed variable, the content of the function is evaluated correctly).Is there a proper syntax to get it to work ? Thank you very much.

Has anybody an explanation why the symbolic solve produces that many wrong solution if used without the modifer "fully"?May we call it a bug? Are there other examples?

Hello, Everyone. Is there a way : ln(e^x), symbolics, ==> x ? ( Mathcad 14 ) Thanks in advance for your time. Regards.

In the attached worksheet I have a summation that works with one matrix variable but when I add another matrix variable it doesnt work. Do I need to use something instead of the list command? Thanks

Bonjour,Je suis à la recherche d'information sur ce que l'on peut réaliser avec Mathcad.Un client me demande de mettrre en ligne une worsheet dans un environnement serveur.J'imaginais stocké la worksheet dans un site sharepoint comme j'ai trouvé sur google ce lien.https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CC4QtwIwAQ&url=http%3A%2F%2Ffr.ptc.com%2Fappserver%2Fwcms%2Fmedia%2Fstreamed.jsp%3Fim_dbkey%3D117604&ei=bbK7U4exI-_T7AawnoCoCQ&usg=AFQjCNHtcMDqQHWzWyRGjb7LS-U_ARVe0Q&sig2=KhcQwMUuZyCxD7GnH39JXQ&bvm=bv.70138588,d.ZGUMais ma question pour aller plus loin est il possible d'interdire la fonction saveas dans mathcad? de lire un fichier mathcad directement en web sans avoir mathcad sur le poste client? via une api par exemple?En gros à la recherche de document sur le partage et protection de fichier mathcad.J'ai vu la commande protect worksheet mais pas bien compris son focntionnement même en cherch

Hi..Can anyone help me writing these equations in Mathcad...?

Respectedcan you help me.In att. you can find two documentsa) Analysis 1 without units - its OKb) I would like to use units in my worksheet Analysis 2- without units but there is a problem -why ??Thank you

PleaseCould you tell me what is wrong with this sheet (in att.).Thank you

Hey!I'm wondering if there is a way to get more than one output from a program in Mathcad Prime? In my case it is a for loop and I would like to output both a message and a parameter (1-by-2 vector).For example:test = "Error in:" [3,5] ...or something like that.Where "test" is the function I'm using.Thanks in advance!

Could someone tell me how should I do to maximally simplify, using the symbolic processor, the following expression?

Can anyone obtain a solution using Odesolve in the attached trial worksheet?

I have Mathcad 15 installed on a Windows 7 computer. Everything works fine except when I want to create a scriptable object (or web control). If I open a file that had scriptable objects in them they do not work...they appear with only small arrows. See attached. I tried registering these as indicated in another post I found online:MichaelH wrote:I stumbled across the solution to this while looking form something else in the Help files.For some unknown reason, the components (.mcm files for text box, list box, and so on) were not "registered" in MC15 when it installed, although they were in the Mathcad folder.The problem is solved by finding "mcmreg.exe" and opening it. A dialog box appears showing various folders. You then navigate to the folder where the .mcm files are located (typically C:\Program Files\Mathcad\Mathcad 15\mcm) and select all the .mcm files and click open. Another dialog will appear indicating that all the files were registed.That's it.

Hi,I am trying to learn PDE in mathcad,.. Its my first time with PDE, could anyone pls help me with this?Thanks in advance

Hello,I am trying to use a solve block to find values for two variables but am running into difficulties. It seems that I am always getting an error "variable is undefined". After searching the forum it seems this is the standard error from a solve block and doesn't really give any clue as to what I'm doing wrong. I originally suspected that I was having issues since I was making use of functions with conditional statements, but after experimenting and removing the statements I am still not getting any results. Manually, I can come close to getting a solution.Please see attached sheet. Thanks.

hello, i want to evalute the interation symbolically. but i am not able to do it with mathcad. please help me to solve this. i attached the problb sheet.

In the attached worksheet,I would like to find the parameters of the GEV that are generated by a booststrapping of the original data. The Maximize function accomplishes this rather well for a data vector but as you can see I am stuggling to do this for an array.I would appreciate any help in accomplishing this.Dick.....

Hi All,I am really having a hard time doing a simple summation in MathCAD. Please see attached file. Can someone advise why is it not solving? Can someone edit and correct it please? Thanks in advance.Regards,LS

Hi,Sorry if this is a trivial question, but I am only starting to use symbolics, and I haven't found how to do what I want.If I manipulate equations that are fully symbolic, the results of manipulations are shown in a symbolic way. But if there is one of the symbols that is defined, it is automatically evaluated and replaced by its value in the results. Is it possible to do that ?Here is an example, calculating the power transfered by sinewave voltage and current with a phase offset. In the first case, the peak voltage is undefined, and I get the expected result : P(phase) = Vpk * Ipk * cos(phase) / 2In the second case, I define Vpk=100, and the result is P(phase) = 50 * Ipk * cos(phase). Is there a way to modify the second case, in order to get the same result as the first ?Thank you very much.Adrien

I have added the DCOL routine to the prode.dll. You may find the updated prode.dll and a test file for the DCOL routine on my website.The dll was built to handle VLE, VLLE, and LLE columns. Only VLE option is available to Prode users with Basic license. I have the Basic license, so I am unable to test the dll for the other two cases. Please let me know if there appears to be a problem with the dll for the VLLE or LLE options.

Hello,i need help on how to iterate until convergence. please scroll down in my sheet until you see the red arrow where i begin the iterations. Right now i have 10 individual iterations, and checking the end for convergence. i dont know how to do in mathcad where you can automate the iteration until convergence, and let it decide how many iteration it needs until convergence. there are two values that each need to converge . one for moment and the other for delta. a ratio of 1.001 will be fine for convergence. Thanks!

Hello,I download the "User EFI Dev Studio Project" file from the discussion "The Down Low on Mathcad DLLs" from Aaron Shaw.I have a question about the different function definition ...In the "C:\Program Files\PTC\Mathcad Prime 3.0\Custom Functions\userpack.c" (or in the Help Centre - Custom Functions) the code is:BOOL WINAPI _CRT_INIT(HINSTANCE hinstDLL, DWORD dwReason, LPVOID lpReserved);BOOL WINAPI DllEntryPoint (HANDLE hDLL, DWORD dwReason, LPVOID lpReserved){ switch (dwReason) { case DLL_PROCESS_ATTACH: { // DLL is attaching to the address space of the current process. if (!_CRT_INIT(hDLL, dwReason, lpReserved)) { return FALSE; } if (!CreateUserErrorMessageTable( hDLL, 3, ErrorMessageTable ) ) break; if ( CreateUserFunction( hDLL, &realsum ) == NULL ) break; CreateUserFunction( hDLL, &transpose); break; }In the "user-efi-dev-studio-project\User EFI Dev Studio Project\USERPACK - DevStudio Project\dllmain.cpp" the code is:BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_rea

Some work on basic aircraft performance.It was used Mathcad 15 version. The file has a printed PDF also just to see the worksheet.A video showing the wing area variation results can be seen on the link: http://communities.ptc.com/videos/5118
