Hello everyone,Does anybody know, if PTC developed the secondary axis function already - for Mathcad Prime? The old Mathcad version had this option.It is horrible without it, for example in case of a Bode plot. I would like to see phase shift and gain on the same graph.Any hints?Or any alternative solutions for the problem?Thanks!

My installation of Mathcad Prime 3.0 on Windows 7 just started printing blank pages whenever I try to print a document.  I printed several documents just a month or so ago with no problem.  It doesn't matter what printer I use or if I print to PDF; I get the same result.  I'm wondering if there was some update to Windows 7 that clobbered Prime's ability to print.  Mathcad 15.0 M045 is printing just fine.  I even re-installed Prime 3.0 and it didn't fix the problem.  Any thoughts would be appreciated.  Thanks!

Hello,I have the following problem: if I set some graph markers I can only delete the last one and not the previous ones. Is there an option for that, that I don't know?What if I want to delete all my markers, to have the clean graph as before?Thanks!

I'm trying to truncate a data sample to an even power of two for input to the FFT. I define j := 0..128 (using colon and semicolon keyboard strokes)And verify by printing j = to confirm that the definition is correct.BUT,when expressing Xsample [j := X[j, I get the error message that J must be an integer, and the help file response stating that the subscript j "seems to have a fractional part".In a second attempt to define my subscript by writing out the definition explicitly, I get the same failure.     0     1     2     3j =     .     .          .     127I''m pretty stuck here and will appreciate help.ThanksBob

I tried to minimize the objective function above, using Minerr function in Mathcad.and i put the guess value of 18 variablesand then finally i could get the  optimized value of thembut i am not sure the work i done is right or wrong, so i need a check.can anyone can check my work?

I am new to Mathcad Prime and my math skills are a little rusty.  I am trying to get a response plot of a non-linear system with Coulomb friction.  The sign of my velocity changes every half cycle.  I figure I need to do some programming to get my response plot.  I haven't had much success and there aren't too many resources available.  I tried the Help and Tutorials and I still am having trouble.I was hoping somebody could assist me and also point me to some good resources on programming in Mathcad Prime.Thanks

Hello,maybe this is a silly question but i've not found useful results in forum.I'm looking for create an array of function, something like :direct_fun_vect(v)1:= v1+ 2*v2 +3*v3direct_fun_vect(v)2:= v1 - v2ect..in a way that mathcad knows that each row is a function of v-vector (v1 , v2 ,v3).I've found a solution writing the single function like :f1(v):= v1 + 2*v2 +3*v3f2(v):= v1 - v2 ect.and then assigning manually each function to a relative place in a vector like :manual_fun_vec1:=f1(v)manual_fun_vec2:=f2(v)ect.But in this way i'cant evaluate directly for example the i-esim function in an assigned vector x : ( 4; 1 ; 7)  Like :   manual_fun_vec1(x) -->I've to do a temp passage : tmp(v):=manual_fun_vec1  then i can do :      tmp(x) ->    to obtain result.I'm searching for a direct assign like :direct_fun_vec(v)1:= v1 + 2*v2 +3*v3 ect.so i can evaluate each function in a for cycle like :for i e 1..Nsum<- sum + direct

Hello all,I'm trying to plot a mathcad xy graph but with results dismal.As you can see from the image , since the variable is repeated the array of points become an integer again and so the graph just shows one point.I know i could multiply the function so that it become x^2+x but this in not a solution since this is just an example for a much more complicated function I need to plot, that would become simply a monster if i would multiplicate all toghether.Hope there's a easy solution for this problem! Thank you

It is equal Black^Blue=const,but i have changed a to 0.5m^(1/m)

Why, working with mathcad Prime, when I try to close a blank  worksheet, clicking on the x in the upper right corner of the same page, the page does not close, instead it is incremented a negative index, each time I click on the x?Thank youFM

Dear all,I need your help to solve this minimization (by symbolic calculation) using MathCAD Prime 3 that I have and use at school. In ordrer to be clear, I attached a picture of what I want to solve. Note that both x, SNR and BER are real positive values.I will be happy with your help.Bests,Max Fréjus

HiI have a question to the cvar() build-in Function. I know how it is programmed. but in my Shee the correct covar for my covar-var-matrice is covar.Kan anyone tell me the relationship between the cvar and my covar calculation?ThanksWalter

Even though i  defined the Guess value of M, this error shows up

I wanted to create the Index table in the Mathcad prime 3.1 worksheet. Like below shown example.Is there any way we can do this in the prime 3.1.Thanks,Anil

Hi, please see the attached. Im trying to find multiple x values of my plot for various y values using Given and Find. I'm not sure how to set it up to give me a vector of y values for a vector of x value inputs.Also, is it possible to draw the rectangle on the graph as per my second request.  Thanks for any helpJason

Hello to all the experts. I am very interested to know whether, in the new version of mathcad Prime, there will be the spelling tool, or not?Thank you very muchFM

i got some  questions,  if someone would answer them, I would appreciate it very much.well there something called nonlinear programming with constraints and also without them, i've been searching in here how to solve this type of problem but what i found wasn't exactly what i was expecting.for example: if i want to optimise (minimize or minimize o just find a solution that fits) a variable of  a single function, a system of equations or a system of differential equations. How can i make it?  there is a sheet attached  with the different types of problem i mentioned.

Hey guys!Im working on Mathcad 15 and i want to know when there is a usable version of Prime is coming out?Is there a Mathcad 16 maybe coming? Or which version of Prime has the same features as Mathcad 15?Im satisfied with mathcad 15 but im not satisfied with the office functionality. Is there an add on or packagewhich adds moore office to mathcad? (Content Page, better writing form)The usability of Prime looks good to me but the mathematical stuff behind is not the mathcad i know.Which real alternative out there is possible with an symbolic fomula input units and office functionality?Best thx,Stefan
