Mathcad

This request is more fully explained in the attached file. The request is for a way to take two single column vectors or matrices that are effectively two columns of a table when augmented (i.e., namely matrix A and matrix B). The first matrix "A" has several rows that have repeated values. A function has been run to create a new matrix "C" that has removed the duplicate rows.Please help to write a function that will create matrix "D" such that "D" contains the minimum values from the second matrix "B" pertaining to rows that had the same value in matrix A. Thus, matrix D ensures that removal of duplicate rows from A does not lose the minimum associated values in "B". I think the details in the attached Mathcad Prime 10 file will help clarify this request.   

By Ronald Satz, Ph.D.This worksheet will:Solve a common two-circuit physics problem to determine charges and energy, keeping in mind the Reciprocal System Theory and the conventional theory  Apply to Physics, etc.  Perform using electric theory, Reciprocal System Theory, capacitance equations, energy equations, etc.      This paper compares the Reciprocal System theory of the capacitor to the conventional one. Conventional theory posits that neutral matter contains an equal number of positive and negative charges. It also states that capacitors, which are neutral overall, have positive charges on one plate and an equal number of negative charges residing on the other plate. In contrast, the Reciprocal System says that neutral matter is charge-free and that capacitors store uncharged electrons; the capacitor "charge" is actually just another form of energy. Consider an electrical circuit with two capacitors, one "charged" and one not, connected by an initia

i attached the file, its quite the problem. i did the actual movement using the acceleration on solid works. but i cant get my Mathcad graphs to match. i just cant help but feel like its due to my lack of experience in Mathcad. 

I'm not able to understand, what's causing the error when I create a range. Please review and guide, next step would be plotting with the values. Using Mathcad 10 

Hey all,I'm a mech e student using mathcad for the first time for my thermodynamics class.Been having a tricky time figuring things out, and already hit a wall. Not really sure how to figure this out, and I don't recall seeing any previous topic that helped, so any assistance would be appreciated.Attached is a screenshot of the issue.

Hi comunity, I need to calculate an Integral of data vectors like shown in the image.Outside the for loop Mathcad has no problem with convergence, but inside the loop MC returns the error message.Is there a trick here, or is this generally not possible?Greetings and many thanks in advanceMichael   

Hi all,I am plotting a phasor (magnitude @ angle) on a polar plot in MCAD 15.  I'm doing it in 15 because I want to make an animation as the phasor changes.    Here is the output: https://relayman.org/temp/e/output.mp4 The red dot you see moving around in the video is the endpoint of the phasor.  What I would like is for MCAD to leave a red dot at each location along the way - so in the end I would have a plot of the locus of those endpoints.  Something like the attached image. thanks  

Hello everyone!I’am trying to solve an optimización problem using minimize function but get an error “This variable is undefined”.What am I doing wrong?CarlosRomero

The solve block is not finding a solution. I'm using Mathcad Prime 10But using the same formula I can iterate a solution I think is convenient enough. What am I doing wrong?I though maybe changing TOL or CTOL would be the solution but no.  

ok.  something you just need to reach out to the power users.   I'm working in Prime 8 and have a simple spread sheet.  not knowing all the available size if I enter a number, I should get the nearest available number to pull data.    This should be simple right.  

Hello everyone,Could someone help me figure out why the options in the outputs of m and n programs are repeating, while the program k works fine? Is there anything i should change in Bop() function?Attached the Mathcad sheet.

I'm trying to write a program in Mathcad, but stuck on this step highlighted below.How to insert the second line in the bracket as show below for return function, thanks 

In the attached file below if i give sub = stack(sub,RA) at the end of program, it gives same options multiple times. could someone please explain, why the program does that?can't attach Mathcad sheet. 

How to apply this program, when the vector has two columns.   Reference topic: https://community.ptc.com/t5/Mathcad/How-to-remove-duplicate-entries-in-an-array-using-a-program/m-p/996692 

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0Good day,How to do automatic "step by step" calculation in MathCAD where in it captures every steps in solving a certain equation.

Hi everyone, when i got a new laptop and donwloaded mathcad again, im suddenly having different issues with it i didnt before. Like when using the solve function it cant give me the answer if i use units in 1 scenario. In the other it gives me the answer as "cos(30deg). Anyone knows if its something i can fix?The one above is supposed to give around 673N. This one is supposed to give 0,87kN. 

Hi there!Thanks to the community members for being patient with my questions.Although a lot of guys in the PTC community gave me  valuable tips,I still want to improve my code slightly (perfectionism). So, I'll try to list  of what do I want to get from my  code:Define all the calculus dependencies in the first step.Define the variables' range (each layer generally has its range). The idea is to account for all possible permutations.The k1 and f functions should be figured out for each set of thicknesses (variable) iteration of my multilayered assembly (I have no idea how to assign a specific range of thickness to a particular layer; this is my weak point; I’m not confident in this area).To sort out what of the total k1 and f values fit the restriction condition and arrange the result in a matrix with headers (for convenience, with aggregated values’ Names) (the particular matrix components should be plottable a

Hello,  Moving to Mathcad Prime 9 from V15, and noticed there are no rules or guidelines to align the different regions of the document. Any suggestions/tips/tricks to align the regions other by eyeballing them?

I'm doing a EDO resolution, and at the end of the resolution block I get error "Exception has been thrown by the target of an invocation"". If someone understood how to solve or the reason for this error. Thanks  

Hi,I have a Mathcad sheet that calculates a 13X3 matrice and then returns a 13X(3^13) matrice. It is a lot of calculations. I have a HP computer with Intel I7 processor and 64Mb RAM. Task manager say it uses about 10-12% of processor and 3-5MB of memory. So far it´s been working on this for about four hours, and it´s not finnished.  What is missing to make the calculation go faster? Are there any parameters that I can change in Mathcad so it uses more power?

Hi there I have some data of depth of 10 inputs  but I need the calculation to start from single point in each input and ignore the one above : for example the starting point of first input is 1.31 but its depth starts from (0) ...so I need the program to ignore all the data from 0 to 1.31 and starts at 1.31.the second input d2 has values from 0.5  I need the program to ignore this values and starts from 1.26 so basically it eliminates all the points before the starting points I decided Prime 10 is attached also the excel sheet  

Hi! I have a twosome question, as I am in doubt if there a better or more straightforward solutions as what I have done currently:A PTC document where I have a mechanic exercise to calculate reaction forces ("StaticExercise"). I would like to know how to format functions, like an area which overlaps pages. This makes in inconvenient. As well, I am very interested how equilibrium formulas can be formatted and solved.In another exercise ("SteelRodElongation_Exersise"), I have applied an IF function, because I would like that the calculation breaks or stops, so it ends up with 0. Now the calculation gives some strange units at the outcome, at Delta L (if you change σ0.2 to 1 manually. What would you advise? I have formatted the questions/notes in red in the files. Like to hear your thoughts!PTC Version is: 9.0.0.0. Thanks a lot

Hi AllLooking to create a calculation which uses a drop down box to select beam size. I would like mathcad to then automatically populate all the remaining characteristics of the beam into the appropriate variables. I have downloaded the AISC shapes database as an excel file so I am using the READEXCEL function to input the excel data to mathcad. A combo box seemed like a really good fit. I'm trying to input columns from my data matrix into the combo box but it doesn't seem to be working. Any ideas? A snapshot of the simple worksheet below.  

We had a formula written in Mathcad 15 that solved a range of numbers and gave a solution of the entire range (see image below). When we convert to Mathcad Prime 9.0 only the last number of the range gets solved (second image). We are looking for a maximum throughout the range so this does not help us very much. Is there a way to write the function in Mathcad Prime 9.0 to give similar results to Mathcad 15? Both files are attached. 

Hej Guys, i am new to Mathcad and not very familar with it i have a worksheet with some functions and no i wanted to use the solveblock to find some solutions for me but i have no idea how i should write it down. i added  the worksheet with the functions. i have a function with two Variables that where i want to find those two variables when i only know one result of the two out put results that the funcions brings me. the constraints i have and the expted result i put to the worksheet. maybe someone can give me some advise on how the solveblock need to be set up for a function with two variables? Kind RegardsMarkus
