Hi all, I am trying to figure out if it is (mathematically) possible to obtain a x(y) function via the following system with odesolve: dx/dy=F(x) Do you guys have a idea if it is possible in mathcad, and if so, how?
Greetings, im trying to program something that fills a matrix automatically, but you can choose wich rows and columns to make 0 instead. So far i can do it by hand, just setting what row and colum i want (fil=row), and adding extra conditions to the "if" I tried to use a matrix instead, like row:=[1 2 3], so if i= any of those 3 values, it assign it 0, but it doesnt seem to work with a matrix, i wrote it something like "if i=fil1_i" (_i meaning subscript), but it doesnt compare it to the value on the matrix. Im working with Power Flow equations, in this part i need to do a 2x2 matrix each space being a Jacobian matrix. Im trying to automate it, because this is with 2 "bars" so matrix are 2x2, but when its something like 6 bars i dont want to do everything by hand
It will be very useful if you help me.
As per this thread, same issue: Hello, Did you have a fix on this issue? Facing same issue but no response from anyone and couldn't find this topic troubleshooting anywhere.
HiI'm converting Mathcad 15 sheets to Prime 7 and I noted thatsome division lines are very faint (but not all). Picture as attached. Is these some way to get a clear black division line to all formulas? Thanks for advice!
Hi, the "solution" shown below is obviously wrong. Any help is appreciated!
ODEsolve issue. is it possible for mathcad to solve an equation with odesolve for: dx/dy=f(x) to obtain a x(y) function?
Implement a function warning that (optionally) highlights a Math Region and displays a message when the user either hovers over or the region or clicks on it. The function would be akin to the existing function error except that, unlike the latter, warning would not halt worksheet evaluation. It's something I've often felt would improve a function's usability. It might also have proved useful for highlighting the effects of partial application (and thus mitigating the need to remove it on the grounds that it confused some users). Here's a rough example of warning's potential use: Zoom in to display Warning and error history - just another thought ... Maybe a function Notifications that presents a list of warnings and errors together with the identity of whatever raised the error/warning? Mathcad Monads ... Stuart

Hi Mathcad-Community,I am running into the following error not able to debug it. First I though, that I might have a unit mismatch but after rechecking, everything seems to be consisten so far. What is the cause for the error?
Hi. Please solve this.This is solving complex numbers
New release date for Mathcad Prime 7.0:
Whilst playing around trying to write a function to remove text rows from a mixed string/numeric matrix (*), I discovered that the undocumented (but very useful) function fold doesn't just work on vectors but also works on matrices, scanning down each column in turn, in the normal Mathcad fashion. This behaviour opens up the possibility of some straightforward implementations of useful functions, such as converting a (potentially arbitrarily nested) array into a vector and summing the elements of an array. Here are some Mathcad Express 7 functions. Or we could define matsum to sum just the numeric elements of an array. Alternatively, we could shift the burden of removing non-numbers to a specialized version of vec. We can even count the elements in nested arrays. The full version of Mathcad Prime allows the user to write programs to create functions. This facility opens up the possibi
Hi everyone,I am currently trying to solve a differential equation in Mathcad. However, after watching a bunch of Youtube-Tutorials on how to use the solve-block with ODEs, I am still not able to get the result. What am I doing wrong? Your help is much appreciated 🙂 greetingsnerphan
Hello Does anybody know how to calculate sum of the function P(r) ? Thanks a lot 🙂
Hi allI have a mechanical problem, but i don't a have a mathematical skill to solve it, I hope that someone could help me👃in first, see simplified drawing: in yellow box , is a winch wire betwen winch and pulley (steel cable,the length is low, the elongation can be a constant, maybe )pulley connected to ground with springwire betwen mechanical elbow and pulley (steel cable,the length is high, i need to use Hooke's law for evaluate elongation, and correct this to calculate good Lw parameter)mechanical elbowmechanical load mg ( for simplify what happens in mechanicel elbow, we consider un traction forces on wire node at elbow)At t0 system at rest : it is as if the spring is a barAt t1, the winch pulls to make an ordered value for alpha Find Lw according to alpha angle, the object of the game is that the winch gives a Lw length which allows to maintain alpha angle according to the instructions (angle ordered) What i feel : variable is a function f(x)=k(x) , here
I can't get this to do anything. It's such a piece of junk.Does this actually work? Won't find anything - won't replace (Text or Math) I am on Prime 7
Hi all, I have a range z from 0 to 11,5m I've created function y(z)I want to extract the values of y(z) as an array and extract the array to Excel. Is it possible to extract the values as an array without converting z to a vector? Best regards,Anders
I've received a file named "sw_license_email_5559049.dat" from email ID "mathcadlicensing@ptc.com". Can you tell where should I copy paste the file and the following procedure? I cannot open .dat file saved in my PC but I can open it through email.
Hi everyone,I am converting Mathcad 15 files to Prime and I encounter an issue that I can't debug. Its about a division between two vectors where the divisor has zeros in it. Prime shows the following error: This expression is divided by zero. It cannot be computed. While Mathcad 15 has no problem with this division. I attached an image to illustrate the problem. Regards,
Hi. I want to try Mathcad Prime 7.0.0.0. I complete form and download mathcad 7 and installed this. I wanted to acquire license, so i create an account, loged and start acquire. It takes really long time (~5-10minutes) and i get comunicate: "License service appears to be busy. Pleasy try again. For more help visit: ....ptc.com website". I tried again and again and it's not working. What can I do? Help me please
how to apply an external font to labels and text box placeholders (hint text), radio buttons -We tried to apply external font by custom class but did not reflect. could you please help apply external font by custom class for all labels and textbox placeholders (hint text), radio buttons?
A hare from point 0 needs to cross a field with a length Δ and with two parallel straight edges as quickly as possible. The hare runs in a straight line perpendicular to the starting edge of the field and comes across the edge of a round section (point 1) where the hare can run faster (this round section of radius r is in the middle of the field). The hare changes direction of running, crosses a round section along a chord, runs out of it with a change of direction (point 2) and finishes along the shortest path (point 3). Determine the hare's running trajectory. Why is the Snell's law fulfilled at point 2, but not at point 1? Where is my mistake or misunderstanding of physics (Fermat's principle)? See please the picture and the Prime 6 sheet in attach. See too The problem of cockroach races - PTC Community
In my company, we use a library of files, which are included in our projects. These files can be for example datasheets of components, formulas out of toolboxes and so on. If we open a project file we encounter very often the problem that include files are marked red, meaning Mathcad reports an error with the file. The fact is, that there is no error in the file:We found a workaround for this, but this takes a lot of time. When you edit the path, you can force MathCad to reread the file and the error is gone. This has to be done for all marked files. Sometimes even this does not work. Then you have to open the corresponding file, recalculate and store it again.As we have include files, which include other files, this can get very very nasty. I reported this already more than 2 years ago, but no reaction. Now this problem got even worse. As the network path changed, MathCad hanged or got extremely slow (hours !), when opening a file with include file paths still on the old, not anymore
Question as per attached Prime 7Thanks
