Hi,I am creating an excel table using the Excel component in Mathcad Prime 3.1. I am exporting the flow rate (which by default is m^3/s). I want it to be input into the table as l/s. Is it possible to do this without completing your own multiplication on the number (i.e. multiplying by 1,000 or whatever it is to convert m^3 to s). ThanksAndrew

Hi everybody,although I looked a little in past questions, I don't seem to find anything suitable.  I am confronted with the problem of reducing the sampling rate of a set of files, if possible with a variable reduction factor. For example setting reduction := 60 I would then have a value every minute, instead of a value every second, and so on. All my attempts are baffled by error: "insufficient memory for the required operation".I built an example with a limited amount of data, in order to show what I am trying to do. But the real files that I have got can reach 1.5 Millions of lines. They are also not readable with Excel.Moreover, the procedure seems to me very slow.  There has to be a better approach, but at the moment I cannot see it.Thanks a lot in advance for any hint!RegardsClaudioPS: a small collateral question would be if there is some easy Mathcad-way to convert the time stamp "hh:mm:ss" in a normal number (like for example seconds from midnight or so).

I am using Proselect in loop to select the model in drawing. and i am getting PRO_TK_PICK_ABOVE error . Can any one explain why.Regards,Manoj

Hello,My problem deals with a system of 2 second order coupled differential equations, Using Mathcad.I issue a problem with the "D" function (used to solve a differential equation) when there is more than 1 parameter inside.Here is the system with 2 parameters Teta1 and Teta2 :I convert this system to have only first order equations : Then, I can't find other way than making a D matrix with my 2 parameters Teta1 and Teta2Then, I issue my problem : its seems that I can't put a D function with 2 parameters in rkfixed method.So, if anybody here can find a way to solve this system, please let me know ! Any other method to solve it is welcome, of course !RegardsKevin

Sometimes when I evaluate a derivative symbolically in mathcad of a certain function, it gives me 0 when its not.... Also, when I try to extract real and imaginary parts of a complex function array, if I extract element by element, it gives me a number, but if i extract all at once, it just gives me [1x1], its a problem because I cannot graph the function. Also, assign the SIZE of a different matrix onto another variable?

Hello,I have got an important .mcd file which I'd like to convert into .mcdx, but the XMCD, MCD converter button in the input/output-ribbon is inactive, i. e. I can see it, but can't click on it.What can I do?

Hello, are there plans to bring back e-Book capability in future Prime releases?If not is there another software product that can take a Mathcad document and turn it into a book or publication document?Just curious,David Penwell -

Dear All, I would like to know if it is possible to create a cross-reference table in the new Mathcad version, like the option that we can find in Microsoft Word.thanks!

There is absolutely no way via PTC support to reactivate a licensed Mathcad version below 14 for any reason. Essentially, the program is hijacked for upgrading to a newer version.

Hi!I'am having a problem wanting to solve a third degree polynomial. This is ok, and mathcad retuns three solutions, but I want mathcad to return only the solutions within a defined range, e.g [0,10]. I have tried to this with an if-function, but no luck there. Uploading a file. Someone please help.BA

Hello Folks,I would like to have a fancy listbox where all the logic is external and the listbox is used merely for choice and display -  such as in the pic. Does anybody have an idea?Raiko

Correct names Mathcad and Mathcad Prime are Mathcad and Mathcad Jr.There are a Father and a Son.The Father is much more experienced than his Son, but the Father had a career coming to an end.The Son can not yet do much of what his father could do.But the son gradually from perenemaet experience of his father and learns a lot what you do not know the father.Yet there is the illegitimate son - SMath.

How  do you solve a boundary value problem in mathcad prime 3.0 with a solve block?  I have been wondering about this for a long time because I want to use it to solve Schrodinger's Equation. Can it even solve BV problems if there is not a unique solution?

What happened to "solve for variable" in Mathcad "Prime" 3.0?  That was one of the most useful features in all of Mathcad, and it really isn't worth having without that.

Hi everyone,I'm a student and I'm new in PTC. I'm trying Mathcad Prima 3.1 free for 30 days. I have a little problem. Sorry if this is not the right section to post this question.I was trying some elementar functions and when I want to raise to power using ^ button, Mathcad returns me the command "if ||" for programming. What's the matter? Using a text box there are no problems. I've tryied all the shortcuts and everything works. This is the only problem, my shortcut (^) for raising to power doesn't work. I'm missing something? Thank you very much for your answers. Best regardsDavid

Hello fellow MathCad users,Is it possible to display the numerical value of variables in a line of calculations. For example if I was to calculate the strength of a beam. I want the calculations to look like the following:Depth of beam:                D = 300mmBredth of beam:               B = 125mmSection modulus:             Z = 1/6 * B * D^2 = 1/6 * 125mm * 300mm^2 = 1.875 x 10 ^6 mm3Bending strength:             fb = 38 MPaStrength reduction:          phi=  0.8Loading duration factor:    k = 0.8  Bending strength:            Mn = phi*k*fb*Z = 0.8*0.8*38MPa*1.875 x 10 ^6 mm3 = 57 kNmFYI I have MathCa

How do I backup my MathCad product in case of failure or hacking of my computer?Regards, K

I was looking at some of the Rosetta Code challenges for implementation in Mathcad and decided to try a couple in Prime Express (as this is what I have).  The major drawback to Express is the lack of programming capability, but there's quite a bit that can be (or should be able to be done) using just range variables and functions that don't make use of programs.I wanted to pick all of the non-zero elements out of a vector and decided to use the until function to sweep through a reverse sorted vector until it hit a zero.   However, Prime keeps telling me that 'until' is undefined, even though I inserted it using the Functions Dialog. Express doesn't raise an alert saying that it's Premium Feature, so I'd expect it work. Neither can I find anything in the Migration Guide or Help to indicate it's been deprecated.  Is there a known problem with the until function in Prime 3.1?Stuart

I am trying to replicate something done in Mathcad 15.0 in Prime but I am having difficulties.I would like to double integrate two functions, but can't get a function dependent on two variable to work.I have attached my best try, and a pdf of how it was done in Mathcad 15.0. I can't get the n(x) to work in the gamma,h1(x) function. I am able to skirt this for a while but never get my integration to work. Please see attached and thank you in advance for your help. AlanStevens‌ I feel like you would have the answer looking at one of your other posts.

Hi,my problem sounds rather simple but still I do not a have a solution in Mathcad. In order to automate my Mathcad 14 sheets I would like to check if a variable is defined or not.If the variable is defined (not red colored in Mathcad) this on should be used instead of an different. Thanks Holger

Hi everyonecan anyone help me to find the best distribution: weibull or exponential distribution for this data using Mathcad, please?1.393    0.66    1.032    0.336    1.451    0.489    1.123    1.789    1.542    0.051    1.654    2.813    0.736    0.637    1.477    0.859    2.017    0.391    0.754    0.26    0.127    0.725    0.842   0.28    0.396    0.022    0.623    1.205    0.312    0.986    0.534    2.818    1.184    0.656    0.315    0.806    0.444 &

Hello all,I'm working with the WRITEEXCEL function for the first time and seem unable to make even the most basic example work.  In the attached file, no file gets written and I am unclear why this would be.Best regards...

I have this conditional formulas between satisfactory and fail .  How can I turn text into a red color if the condition is "fail". Only the FAIL  text will turn to red color.
