Good morning community. I am trying to interpolate with certain conditions with repetitive data, a way to program, please if someone give me an idea. Mathcad Prime 6.0.0.0 is being used. Thank you for your attention.   Translated by the Community Moderation using Google Translate ----------------------------------------------------------------------------------------------- Buenos días comunidad. Estoy tratando de interpolar con ciertas condiciones con datos repetitivos, una manera de programar, por favor si alguien me da una idea. Se esta usando Mathcad Prime 6.0.0.0. Gracias por la atención prestada.            

Hi everyone, I hope you are fine.I need to change the color of the result word, if it was safe to be green and red in case of unsafe.      

I need to plot the intersection and return it as a value.I have lines to show minimum and ideal operating temperatures but I would like to find the cut-off temps for each of the proposed AC-DCs. I have a graph that has the output derating so the line isn't a simple ab2+c so I have to use a function. I would like to know the maximum operating temperature of the multiple power supplies. Based on a Wdc1(Tempamb).  I tried using solve but this doesn't appear to work on functions. as the derating is not constant across the full operation range. see the example of the function I am using below. What is the best operation to achieve this? I have attached the worksheet for referenceI'm using MathCAD Prime 8  

Hi,I am new to Mathcad and face some problems. I have attached a file in which I am trying to plot the displacement using the Piecewise Linear Interpolation method of structural dynamics. I have defined all variables and put them in the loop, but when I try to plot displacement (u) versus time (t1), I get an error "this value must be a vector".I would really appreciate it if you could help me resolve this issue.      

Hi everyone.So I'm new to Mathcad and I wanted to create circle from form (x-1)^2+(y-3)^2=10, but everything that I can find about plots is way too advanced for me. Any simple way to do circle from form like this above?  

Hi, Could someone explain why I can't vectorize method 2 in the attached work sheet? It returns error message "this value must be a vector". The output of both functions being multiplied seem to be vectors, so I don't understand why I can't use the vectorize function to do an element per element multiplication. Thank you, 

how can i transfer my mathcad license from one laptop to another 

I"m not well versed in IT details but if I can install MathCad on my teaching laptop somehow I would use it a lot more and teach with it since it can benefit my students. Currently we have Prime 6.0.0 on computers in a lab but that isn't convenient for me to get to. If I can understand some basic details about how or what to do or bullet points to discuss with my college IT department, it would be a blessing.  I have a 2022 Apple M2 Pro with Sonoma 14 os.

Hello, I am need of assistance with licensing for MathCAD 3.0 prime. We currently have Mathcad 3.0 installed on one computer and would like to install it on another computer. However, I am not sure if our current license allows for multiple installations with only one user/computer at a time since we only have one license of Mathcad 3.0. So I need help verifying if our license is a flexible installation license where would could use it on different computers but one user/computer at time? If not, what are my options for obtaining another license for Mathcad 3.0? (PS. I could not create a support ticket since I do not have a product code for Mathcad 3.0 prime. I looked through all of our licensing emails back in 2014, but could not find an actual "Product code")

What function does <PROPERTY name="USE_TRANSFORM"/> serve in the file mathcad.p.xml?How can I pass a transform file (MST) to the MSI when using the PIM installer (setup.exe -xml "%~dp0mathcad.p.xml")?Is this possible through the mathcad.p.xml?  Is there a way to configure directly in the mathcad.p.xml file to prevent the creation of the program menu shortcut for "PTC Mathcad License Wizard" to C:\Program Files\PTC\Mathcad Prime 9.0.0.0\LicenseWizard.exe?Thank you.

Using Mathcad Prime 8.0.I am trying to define a variable in a matrix format, where variable has an index i= 1,2,..5.I am able to define all variables, but cannot use a single entry, let's say d5. What is the proper way of defining my variable in such case? I tried with both matrix and table, getting same, "underdefined" fail. I also would like one oth the variables to depend on the others, namely l3=h-l1-l2-l4-l5(these are partial lengths of the entire hight of construction). Can one define such variables in Mathcad Prime? 

Hello,In MathCAD 15, you can use " If" and "And" to satisfy two conditions. i don't see" And" in Prime. How do i do that in Prime? Thanks,Sam    

J and Big Omega are 3x3 matrices. Little omega is a 3x1. Mathcad will not solve this with the matrices defined and gets the wrong answer with them undefined. Nu should be equal to (Omega)*J*(Little Omega). Any idea why this is happening?(Mathcad Prime 9.0)        

This month’s challenge is fairly open-ended: create art in Mathcad Prime. Using the Chart Component, XY Plot, Polar Plot, Contour Plot, or 3D Plot, create some kind of image that evokes the beauty of math. It can be as simple or as complex as you want. Here are a couple 2D curves I created:   Here is a surface called a “monkey saddle” along with 3D Plots of its Gaussian curvature and mean curvature:   Feel free to make something light-hearted and fun. Someone posted an equation for the chest symbol for a certain caped crusader online. Here is that equation adapted for the Chart Component in Mathcad Prime:   One resource that I have used for my curves and surfaces is “Modern Differential Geometry of Curves and Surfaces” by Alfred Gray. Many of the equations can be adapted for graphing in Mathcad. What art can you make with Mathcad?   Find the Mathcad Community Challenge Guidelines here!  

After Mathcad 15 worksheet conversion into Mathcad Prime 9 I'm getting an error: Please help. Mathcad 15 did not produce an error on those matrix division.  

Can i update my READEXCEL value automatically by updating my excel instead of redefining it again? 

HiI need use command addline.I don't see the command addline in the PTC Mathcad Prime 9.0.0.0I had seen this command in previous versions of this program, but not nowplease guide me.  

Hello, I recently updated from Mathcad 15 to Mathcad Prime (8.0) and am having a problem with certain worksheets that contain a specific type of program. Specifically, programs where the calculation is dependent upon elements from the output vector that should already have been calculated. ie  x[i = x[(i-1) + y[i (sorry for the notation - can't work out how to get subscripts on this forum). I have attached a simple example worksheet of the problem. Is this type of self-referential programming no longer possible. If so can anyone suggest a work-around?   Apologies if this question has been asked and answered already. I had a look using the search function but was not able to find anything obvious. Many thanks for any assistance. Ian

Will PTC close licence for MathCAD 15? Or licence will be still available, just support will be available?    

Good morning community. I am new to using this program, the question I have is how to generate a matrix from the combination of results of 02 functions, I attach the question file.

I have this weird issue that whenever I connect my phone with my computer via usb cable, my mathcad license will dissapear and whenever I try applying it it prompts me with this error. The license request failed.Requesting MathcadPrime ...C:\Users\kleol\Desktop\sw_license_email_278734.dat: (-9) Invalid host. If I try yo share hotspot from my phone, instead of using ethernet through it with a usb cable, the license appears again and if I try to activate it it works well. Does anyone have any idea how i can fix this issue? I am also using a 30free trial license.  

I am Working on a Satellite data, where information is stored in a Raw data exchange format .prd file, i have extracted the information in csv file where i got the I and Q data in decimal, now i wanted to apply fourier transform, power spectral density for getting the doppler. i am working on python can anyone help me regarding this...Note that i have a large data set which is about 144crores but i have divided it into chunks..Thank you     

Hola a todos, Soy nuevo en publicar aquí.Como puedo encontrar el valor que le corresponde a un numero de una matriz (buscar) en una columna de una matriz X. en caso que el numero se repita varias veces se pueda poner el máximo y mínimo para ese numero.Gracias de antemano por la atención prestada.             

Where is my or Mathcad error? May be I must have not a & b, but a, b & c? See please the attach. Answer please as Prime 6 or pic or pdf
