Mathcad

I know prime doesn't get any love around here, but it also has many users.  Mathematically, it usually does what I want.  My top gripes are mostly about GUI issues, but I never see anyone else complaining about them -  while they make Prime almost unusable for me.  With a bit of work I've been able to get PTC to duplicate them - but they don't seem very keen on fixing them.  So, my question is - am I somehow the only one seeing this?  Other computers in our organization do the same thing so I 'm assuming it's universal.  Yet the lack of outrage is surprising. GUI bugs: 1.)   Solve block equations - will suddenly switch to only being able to move/snap them 2 squares instead of 1 (note, I'm using the small grid pattern).  Works fine for a while and then it loses its brain and can't align with other equations.  Minor issue, but annoying. 2.) Select box does not follow the mouse when it crosses pages (when inside a collapsibl

Hey im going to exam monday. Unfortunately I can open my notes anymore. Can someone please help me. Thanks

Dear all,I wish I could interact with text region of a mathcad document using a VBA form.Does anyone know a way to access to text region object (I'm talking about sentences, not string assigned) ?Thanks by Advance.François

    Hello, I have a system of equations, and i would like to collect the variables (and its coefficients) at the left side, and all constants on the right side. Is there a way to accomplish this? I have tried the collect and simplify commands, but that couldn't do it...

What goes wrong here?      

Can someone help me with this? I am trying to replicate this resolution on MathCad but I am doing something wrong or not using the right functions to solve it. Can someone tell me what am I doing wrong? Thank you in Advance.

Hello everyone. I wonder how to have a sin function with 3  cycles (or more) that each cycle of it has different number of iterations. For example, I want iteration steps to be 1 in the first cycle and decrease to 0.5 in the second and third cycles (without decreasing or increasing the number of cycles).    Physical Mathematics

  В этюде будет рассказано, как на компьютере можно рассчитывать параметры подвесной канатной дороги и о многом другом интересном, связанным с цепной функцией. Кроме того, рассказано об электрических цепях и прожекторе.  .Цитата из этюда:"Задача о провисании цепи, которую мы только что описали, довольно тривиальна. А вот более сложная и более "свежая" задача. Она возникла во время прогулки одного из авторов по дачному участку, где висят не только пожарные ведра (см.Этюд 12. Нечеткое множество или Оптимальное пожарное ведро), но и электрические провода, натянутые между столбами. Так вот, на одном проводе был подвешен… кирпич для того, чтобы ветер сильно не раскачивал оголенный электрический провод, и он не задевал соседний."Вот этот кирпичФайлы задач этюда в аттач.Рис. 7.1.

By Faouizi Amar Displays curve-fitting non-linear models using the Gauss-Newton regression method  Important for many industries  Shows how a FOR loop iterates through the algorithm until convergence of the model parameters is reached using Mathcad's in-line programming capabilities      Curve fitting is often used to analyze and interpret experimental data, which is usually a large collection of points. The goal is to find a model function that fits the trend and level of the data. PTC Mathcad helps you to do this.       When fitting data to a particular model, it is common to transform the model to a linear one and then use some type of least squares regression. In many cases, it is not possible to transform the non-linear model into a linear one. Sometimes the transformation is possible but results in loss of sensitivity. Under such circumstances, direct non-linear regression should be used. There are many algorithms that have b

Can anyone help me solve this equation? I tried everything but couldn't manage it.   

  Building a new Dell 7720 laptop to run everything from modeling, Mold Analysis, MathCAD, Bunkspeed, Keyshot etc. Already getting the NVidia M5000M GPU.   1. With Creo 4 starting to support multithreading is it now finally faster to go with Xeon? 2. Since I'll be turning off the onboard GPU that isn't a deciding factor for a CPU 3. Which do you guys recommend?? Leaning toward the E3-1535M V6 for the fastest clock.   Thanks!!!

Hello all, I have two simple functions similar to each other. One of them shows different values correspond to different values of x, but the other one only shows a unique value. I wonder if it is a Mathcad bug. How can I have both functions give me values correspond to those of x?

Hi I am doing optimizing, and need to minimize the  error below . (by using Minerr in mathcad)But before that,  problem is this error.

Hi everyone, I would appreciate if someone would like to share his/her experiences concerning the numerical integration function. I am aware of what the help says, namely that "Sharply peaked integrands, or functions whose shape is not readily characterized by a single length scale, do not evaluate accurately. This is the nature of numerical integration. Accurate results may be obtained by breaking an integral into pieces and separately integrating around the peak and away from the peak.".  I am experiencieng some difficulties integrating artificially generated earthquake acceleration time histories (discretized, of course, for example with a sampling rate of 100  or 200 Hz) to velocities and then to displacements. Admittedly they are peaked (see attached example), but I am surprised how often the standard integral function of MathCAD 15 fails to converge (with autoselect, or with Romberg or Adaptive).  The convergence problems happen if I use linterp

Hi all, I have a function with 6 loops (0 to 5), but when I try to keep track of changes of two parameters (alpha and betta), they are returned as the last members of two 1by12 vectors. The numbers of my data sets (x and y) are exactly 12, but I dont know what is the relationship between the these two. I wonder if somebody could take a look at it?Best,   Physical Mathematics

I am using Mathcad Prime SDK 3.1 for Mathcad Prime 4 to automate some time consuming calculations and worksheet management. As described in SDK, the communication is done over an ApplicationCreatorClass() call. This works more ore less fine but I cannot control to which running Mathcad instance the link will be performed. My question is: Is there any way to establish connections to different  Mathcad instances running on the same computer?

Hi   Need some help to create an equation for the 6 cases of  linear graph I attached the mathcad prime for your reference.  I cannot make the graph straight using  this formula ( y= mx+b)  because x  should be   in  logarithmic  distance       Physical Mathematics

Is there a built in function in MathCAD prime that can create pair combinations of integers from two dissimilar length vectors filled with integers? 

Hi,   Earlier i am able to protect / Lock the area with password in Mathcad 15. But i am not able to get the option in Mathcad Prime 3.1. So please can some one explain the process. Addition of snaps are appreciated.   Thanks, Prashant Pandarkar

Recently our company installed SolidWorks PDM Pro for document control.  PDM Pro is similar to PTC Windchill.  More of our office documents are getting saved and controlled using PDM Pro.  Does any one have experience with Mathcad 15 and PDM Pro?   Cheers,

There is no Polls now in this community, but I ask you what we must do now 1. Change formulas in references books 2. Change tools in Mathcad, Maple etc 3. Nothimg 4. Others See the picture please

The Mathcad 15 M050 release that supports Windows 10 was supposed to be 2nd quarter of 2017 according to the Roadmap.  Has anyone heard anything at the PTC events on when this is actually supposed to hit the street?Thanks,Jeff

I heard that Mathcad 15 M050 will be updated with newest C++ and .NET. Is it true?
