Then I flew recently in an airplane and saw a neighbor on the screen of the Mathcad tablet with such a strange example. Then I realized that this is a Jewish or Arabic version of the package.
To all experts, I am breaking down an investigation I am hoping to do to simple blocks. I am looking at creating “dummy” bi-modal PSDs to meet a specific rms value. See attached mcad15 sheet If I specify the values fn, zeta1, A1, alpha and p is there a way of Mathcad finding the zeta2 value required to get a given rms value? A solve is returning “no solution found” but it works with a Find(). I believe one cannot use Find() in a program Ultimately, I would like to create a number of f dummy PSDs with the same (or near) rms value by changing the parameters. For example, I would like to specify a series of alpha values and get a vector of rms value Thanks Regards JXB
Hi Can someone help me with some pointers to achieve above. Ideally - file can be dynamic but will settle for a static file. Sample file attached

Hi I defined a function but right below it says its not defined. Please let me know the issue? Very bottom of the document Thanks Prashanth Rajendran
Find aL and replase to a.L - Ctrl+h No problem to do it in Mathcad 15 How can I do it in Prime?
Problem. A chain is taken (absolute flexible and inextensible thread) of length S and with a specific (linear) mass mc. The chain is suspended at the same height from two ends. The horizontal distance between suspension points is L. A pendant (material point) of mass M is strung on a chain, which can slide along the chain without friction. What will be equal to the arrow of the sag of the pendant?I solved the problem numerically. Is there an analytical solution?
Hi Attached is a calc Im working on. Everything seems OK until I try to enter a value for epsilon/D and then the program keeps popping that it must be a scalar value. Progressively I wish to use the value of Epsilon/D and then calculate Cf. Here also the program keeps saying Cf is not defined. Kindly assist. Regards Shastry
I have an initial matrix containing "Yes" and "No". This initial Matrix is named A. A can start with a "Yes" or start with a "No" and the times "Yes" and "No" are in the A Matrix should be unlimited. In A the "Yes" and "No" do always alternate, they never repeat. Then there are two matrices which are really vectors; B and C. I want to stack these two vectors which might have the same number of columns or might not. For this case A, B, and C always have one row. Recap: A is manually input; B and C are also manually input. Matrix D is generated. Matrix D is the generated Matrix which is going to have one row. For columns it will have the sum of the columns of B and C or simply the number of columns from the A Matrix which should be the same as the sum of columns of B and C. D’s first element will be
Final goal is to output a Graph with X and Y values. I am having problems with the generation of the Y values. The Y values depend on weather an initial value is "Yes" or "No" under the variable Assembly. I would like to replace matrix B and C for a single matrix that will take into account the Matrix called Assembly. If you look at both examples, SW-1 and SW-3, you will notice that matrix B depends on weather Assembly starts with a "Yes" or a "No". Matrix C is simply the cumulative addition of matrix B. I was thinking of creating a Loop that starts with Matrix ShearWall.Gap and applies the multiplication ShearWall.Gap0 times (v.shearwall-v.diaphragm) if Assembly is "Yes" or -ShearWall.Gap0 times (v.diaphragm) if Assembly is "No" and then continue doing what Matrix B and C are doing. Stack the C values and be able to graph them. Thanks for any of your input.
I want to make a dynamic report using Word and MatCAD (15 M045).However, I ran into some problems: 1. Formulas typed and formatted in MathCAD lose their style (underline, italics, etc.) with a special insert in Word. Is it possible to somehow fix this? 2. Noncritical problem: the Russian-language text from Matkad is inserted into the Word with hieroglyphs (solved this problem through the GOST font, it does not give distortions). Is this an encoding problem? I apologize for the errors, wrote through Google translator. Дублирование на родном языке: Spoiler (Highlight to read) Я хочу сделать динамический отчет с помощью Ворд и МаткАД (15 М045). Однако, я столкнулся с некоторыми проблемами: 1. Формулы, набранные и отформатированные в MathCADе теряют свой стиль (подчеркивание, курсив и т.п.) при специальной вставки в Ворде. Возможно ли как-то исправить это? 2. Некритичная проблема: русскоязычный текст из Маткада вставляется в Ворд иероглифами (решил эту проблему через шрифт ГО
I try to create a symbolic matrix (in my example, the matrix RES ). The problem is that I cannot have the result in the form of a matrix, the only way to obtain what I want is to say that RES is not a matrix and is depending on two others variables corresponding to the indexes of the "matrix" (RES2 solution in the attached file question.xmcd). However, I need to use this result after and I need to have the result in the form of matrix. How can I do to obtain my result in the form of a matrix ? Thanks !

Hello all, whenever I try to solve this mathematical equation, it always gives me an error. I am pretty sure I am doing osmething wrong or not writing the equationj ina proper way, but until now havnt found out any solution to fix this problem. It will be very kind of your experts to kindly help me out in this small issue. The file is attached, in this file you will see "b_limit", which always shows an error for bing_bent, can anyone help me out to solve this please? Best Ashutosh Mukherjee
Attached is a little problem in 4.0 that has me stumped - not sure how to set it up to solve. The problem is for a pump - which we know performance of. I need to find the speed to deliver the required flow and pressure must exceed the requirement (it can be higher) and the speed should be such that the consumer power is lowest while meeting the flow & pressure needs. Since efficiency/flow/head curves vary it's possible that the lowest power speed delivers more pressure than necessary, but does so efficiently. Everything works up to the solve block, and despite many attempts I can't figure out how to formulate it. Thanks,
I need to create paths(creating matrix of coordinates) just check image that i have given below is there any simple method to solve this ? this graph has to be plot in x and y coordinates.
To all, I am looking/thinking about something and would like to know if it’s possible to create vectors populated with random numbers. I have only started thinking about it so don’t throw a stone at me if it’s so obvious. In the attached mcad 15 sheet, I have an equation which is the sum of j-values (j=3 in my example) Is there a way of generating the values in the vectors in a random way so that the vector length is changed by the user? For example I may want a 1st pass with j=10, then j=20 and maybe j=100 The constraint is that for the vector fnv: f1 < f2 <f3<…<fj Would this be better set-up as a MonteCarlo problem using mcad buil-in function Thanks in advance
I understand that my S 2 and L x are both defined as vectors. I’m using a comparison operator (<) that compare scalars, not vectors. I have no clue how to make an if/else if statement work. Any assistance or advice would be extremely appreciated.
hi, Can we integrate solidworks with Mathcad prime 5.0? if yes , can someone please send me the procedure. Thanks in advance.
Hi, i need some help with a calculation. Here is the link to the earlier calculation. https://community.ptc.com/t5/PTC-Mathcad/Intersections-Calculate-2-circles-Analysis-Math/m-p/592999#M184561 This calculation calculation is about the stroke arm in connection to the angle of the liftarm. The solution to solve this problem was to calculate the intersections of the two cycles. In the dokument "Berechnung_Masse_Hub" is at the first site a picture of the geometrie. The following calculation i need is to calculate the speed of the stroke zylinder. The angular speed is constant, i like to have these angular speed as a variable. At the end of these calculation i got a diagramm, where is on the x-axis the stroke of the zylinder in mm, and at the y-axis is the stroke speed in mm/sek. Thanks for helping. Marc
Lately I've been playing around with addons of various software products to see if they could help with integrating reoccurring design tasks across software products that do calculations, technical drawing, and finite element modelling, and building information management (BIM) Looking at the webpage https://support.ptc.com/support/mathcad_downloads.htm there are links for a number of addons. In particular I'm interested in the 3rd, 4th, and 8th items labelled "PTC Mathcad Add-in for Microsoft Excel", "PTC Matchcad/AutoCad Integration", and "PTC Mathcad/Revit Integration". When I click on any of those links, I get a "Document Not Found" page. The instructions it gives are not helpful: "Please try one of the following methods to locate your document: Click on your browser's BACK button to return to your previous page. Select a section from the top navigation bar. Use the search tool located at the top right of this page." My questions are: How are those add-ons accessed by
Hi, Function for evenly spaced points in Mathcad 11 or later. Can easily be written for Prime.
I am writing a program and would like to use an if statement with the following format if X exist if X does not exist Running Prime 5. I did not see this as an option in the help files. Mathcad 15 does not appear to have the feature either David
