Mathcad

  I am now converting chapter 23 from book "2^5 Problems for STEM Education" to the chapter of new book about Mathcad and Python.Look at the attachment! Do you have any comments, suggestions and additions to this chapter.  

Does anyone know how I can read a binary comtrade data file.  In this case "File.dat"What is comtrade? See https://en.wikipedia.org/wiki/Comtrade.I am interested in displaying the File.dat The others are easy to open in mathcad.Once I can view it then I can do further processing to it in mathcadThanks.

Hi!So probably a pretty stupid and basic question.The function. All functions are linear btw.f0(x) := C(x)*f1(x)+f2(x)And i want to solve for x when f0 = 5 (just a random number) Hope it makes sense. Thanks in advance

You cannot have a text index in Prime! But if you can't, but really want to, then you can!    

A non-square matrix can have left and right inverse matrices. Left and right inverse matrices may not be the only ones. If a matrix has both left and right inverse, then it is invertible and m = n.Let M be an m x n matrix, i.e. defining a linear mapping from Rn to Rm.1. If n < m, then there can exist a left inverse L matrix n x m from Rm to Rn such that LA = E (the identity matrix), the condition of this: Ker A = 0 (the mapping A is one-to-one). 2. If n > m, then there can exist a right inverse R n x m matrix from Rm to Rn such that AR = E, the condition of this: Im A = Rn (mapping of A to the whole space). How can we calculate RIM?    

Hello everyone.  I'm trying to make a spreadsheet that graphs partial uniform loads and seem to have run into an issue. It all works for the most part. However, when trying to graph, the graph typically "fails" in certain places. See my attached file and notice the missing portion of the graph at x=8.4ft.  Is there any way to fix this? Note that I've already tried messing with the TOL global variable to no avail. It usually causes the break to move to a different place in the graph and doesn't actually fix anything. If it does fix it then it is usually just for that one case and if you put in different loads/locations it'll break again. What should I do?

After windows update, i can no longer use the CTRL+SHIFT+M shortcut to add a math region on the canvas or in a text region. I use this shortcut heavily every day, anyone else have the same issue?

Who do I call or where can I fill out a support ticket.  Support documentation takes me to products I didn't buy.   

To all,   Note a mathematical question per say but one about “shortand” with Mathcad 15. Is there a way of defining the coefficient of a polynome (say as a vector) and tell Mathcad that I want a full polynome like this: P(x)=a0+a1x+a2*x^2 + …. + an*x^n   (= SUM (an*x^n)) I can see the factor and expand commands but cannot find anything that does what I want/looking for.   Thanks

Hi,We have multiple seats of MathCAD prime 7. How can I copy the template settings to another installation? On Creo parametric for instance there is a config.pro file that you can place in the user's profile that sets up the templates and other settings, according to company standards.

One of my users asked this question. Is it possible to have multiple versions of MathCAD Prime loaded on the same computer? He has MathCAD 15 and MathCAD Prime 6 already installed and would like to add Prime 7.  

You cannot put legends on Plots in Prime!But if you can't, but really want to, then you can!

Red shows symbolic error. Mathcad 15 Prime 7  

I am looking for a tool that allows me to access the edit or save history of a file in Mathcad Prime, much like what is found in Creo. I cannot find what I am looking for in Mathcad Prime. Any clues? Regards,/Mark

Hello everyone  I'm very new to Mathcad and I'm trying to learn my way through it so excuse me if my question seems kinda obvious.I've been trying to make Mathcad rewrite an equation for me.Here I want to rewrite the equation in terms of l but I can't figure out how, could someone help with that please?

NOT RUNNING

Instead of the current way:L :=10ftF:= 5000 lbfM=F*L=50,000 ft-lbf It would solve like this:L :=10ftF:= 5000 lbfM=F*L= (5000 lbf)(10ft) = 50,000 ft-lbf It would help checking calculation packages especially if defined variables are coming from a referenced  worksheet file or 50 pages earlier.

And we are all chemists a little or a lot.The word Chemist in Russia has two meanings. Firstly, it is a chemistry teacher at school or university (химик is a man, химичка is a woman), a chemical worker and a scientist. Secondly, a "chemist" is a person who does a little "chemistry". Example. I have to pay tax, but naturally I don’t want to do it. I believe that the state is spending my money incorrectly. I will "cheat" (похимичу - do chemistry) a little and pay less than required by law. Chemist's Day, October 23rd, is also my birthday. Today I turned exactly 73 years old. It is easy to remember - in SI there are 7 basic units of measurement, and in the CGS - three. PS By the way, the word mol (моль) in Russian is both the amount of a substance and an insect that flies in the house and can eat a fur coat. This insect does not like chemistry - naphthalene. PPS But I'm a real chemist. See for example Chemical Kinetics with Mathcad and Maple | Viktor Korobov | Springer

Is there a way to position the plot markers automatically based on a variable value instead of manually typing the value?The vertical and horizontal markers, which are shown red & green in the attached image Thanks   

I am using Mathcad Prime 7.0 7.0.0.0Range Variable Evaluation results in Error at Other EquationsHere are the errors that I faced"This variable must be an integer".A range variable is used to evaluate other equations.When the range variable is evaluated, the other equations do not evaluate, for reason that "This variable must be an integer".When the range variable is NOT evaluated, the other equations evaluate, as expected.See attached screen shots of equations, one shows the variable evaluated, the other not evaluated.  By request, sample worksheet added. Question: What am I not understanding about the evaluation, or the NOT evaluation of the range variable?ANDAnother question might ask if the variable can be evaluated as an integer so that subsequent equations will still evaluate.Thanks.MGM

Dear PTC Prime,I hope this message finds you well. Could you please help in setting up PTC MathCad Prime into my computer?Thank you in advance. Regards,Laurent

Hello   I am pretty new to mathcad. please help me to solve this .

I am using Mathcad Prime 7.0Attempting to add grid lines to a plot but the information in the help section for 7.0 does not match what I am seeing in the application.According to help I am supposed to click the Axes tab in the Ribbon then click Axes Styles: X GridlinesHowever the only tab in the Ribbon I have is Plot. There is an Axes area under that but there is no option to change styles.Guessing there is something I need to turn on or change to I can see and make changes to the Axes Styles but as yet I have not been able to find what that is.
