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

I have a bunch of images I would like analyzed for a specific "shape_feature".  I would prefer not to have to point to each one individually.  I would like to write a little program (in Mathcad) that points to a directory, does the image processing and gets the "shape_feature" I want and then goes to the next image in the directory.  I think I know how to do this except I don't know how to have Mathcad point to a directory and look at all the files in the directory.  Any help would be appreciated.

Hi all.  Here's my question.  I would like to be able to line fit an iso-line.  Mathcad clearly can generate the data for the iso-line since it plots it on a contour plot.  Is there a way to get the coordinates of the iso-line so that I can fit it to calculate the y-intercept? Or maybe there's a completely different way to solve this problem.  Attached is the Prime 3.1 file and pdf that will explain what I'm after more clearly.Basically I'm trying to generate the red lines I've overlaid here (with a paint program)

In Prime 3.1 symbolic evaluation of d (sin(6) x)/dx yields sin(6) (x), while I expected sin(6).What did I misunderstand?/Henning

Good Morning MathCAD Users,Would anybody be kind to help me with the attached worksheet, my goal is to generate a matrix by reading in a matrix in Mathcad 15, but I was getting an error message. I solve the same problem in Mathcad Prime, and it works. Please see if you can tell me what I'm doing wrong.Regards,Moses

Good Afternoon MathCAD User / Attention Valery,This is to inform you that the worksheet that you are helping me with did not generate the right Matrix output.Please see attached. The correct matrix is shown at the bottom page of the worksheet as a pasted copy.Regards,Moses

Sorry if this has already been asked/answered. I did look I want to enter a long expression and have it wrap so that it stays within the page margins.In older versions of MC one could use control-enter to wrap to the next line but that does not seem to work in MathCAD Prime...Is there a way to create a multiline expression in MC Prime?--D

I want to create a "drop down list" with steel profiles in order that after i choose the profile, it automatically generates it's respective properties like Area A , Moment of inertia  I.x and I.y , etc...

I have been running MathCad 14 with Windows 10. Print Preview was working but now when I try to use Print Preview it crashes and MathCad shuts down. I tried repairing the installation but this did not fix the problem. Any suggestions?
