This sheet first plots a series of x,y,z data points for a floor elevation survey. surface is plotted as raw data Then it does a surface regression analysis and generates a polynomial the poly surface is plotted. I need to determine the curvature and then radius of curvature for any and all points.  I will use an overlay of distress to determine the radius of curvature that causes distress, I currently have a slice method of raw date and of the surface  but this is cumbersome.  A math prof colleague provided a solution  that runs OK on his old version  of Maple.I'm attempting to get this solution using MCAD 15 but getting errors.  I think it may be  a simple deal but don't know.  Can anyone help? I've placed a number of markers in this sheet in Bold large font red text..  Solution  starts on page 9.  There's  hand written solution  at top right of page 1 and repeated lower. BTW this is a

I would like to go through the same worksheet several times, changing "index" and the various parameters, and put the calculation results in the same Rez matrix, in the corresponding "index" column. Unfortunately the previously defined columns are set to zero.

I'm currently running PTC Mathcad 9.0,0 on Windows 11 Pro.  After renewing my license, I received an email with two license files. One of the text license files has the word "standard" at the end of the file name. which do I use?   I've opened each in a text editor.   I do see at least one difference.  I see the word "BORROW" in one of the licenses.    Any idea why I would receive two licenses?  What are each for? 

Warm greetings to all,I remember that a few years ago, a post was published asking how to write one or more points overlapping the function to be derived, instead of one or more apexes, but I can't find it, so how can I do it especially for MATHCAD 15? the difficulty lies in placing the dots on the functions, then we proceed with the prefix operators and the like. Thank you very much.

How can I exculde some values to get the function runing without affecting the results? I want to exulde the zeros.It is on page 28 Thanks in advance  

Mathcad Prime 10File Attached. When evaluating a range of inputs for the program shown, the outputs are correct.  I need to assign the  outputs to a variable as a column vector to use in subsequent steps.  When I assign the program outputs to a variable, I get error "This value must be a scalar or a vector".  1. If the output of linterp_2D(A,B,Data,a,0.25) isn't a column vector, what is it?2. How can I create a column vector (or anything else) from the program output so that I can assign it to a variable?  

 In the thread on "Roots of polynomial #3 and How to find unique values into a vector/matrice?" there is a Sept. 23. 2024 post from Werner that uses a function implicitplot2D. I gather from the results and descriptions that this function returns the x-y pts within a defined region where the specified real/complex function = 0 (or close?).  I got around to playing with the attached mcd11 file that has the programmed definition fro this function, and I'm interested in the implicitplot2D function details. I started looking at the function program implementation in the mcd11 file, but it's not something I will work out in the next few minutes. Diverting to the easier path for the moment (find out what has already been done), I found a reference to an implicitplot2D function link in Werner's Mar. 5, 2017 post. The link leads to https://community.ptc.com/t5/Mathcad/implicitplot3d/m-p/332011 ("3d" seems to be in the link, although it advertises itself as the 2d l

Hello Everyone.From : To : How to Demonstrate ? Thanks in advance. Regards. Loi.

How can  I solve this problemI use prime 9 

Hello everyone,based on positive gqo values in q, i want to store the values in Res in the program a.And get the result of 'a' as the length of RA.How can i do itattached the Mathcad 10 file.

Hi I have a set of values that varies along with elevation. I need help plotting the function but can't figure out how to proceed. I have described my issue in the attached file (prime 7).  Thank you very much for your support. 

Im trying to plot, lifetime as a funct. of doping, and abs. coefficient as a function of wavelength. I've looked up some videos and good instructions from this Solved: How to produce a log based range variable or plot ... - PTC Community but I have a problem getting the plot to show while defining the range correctly, ie, units for the start and stop, adding steps. I can pull it up with python but not with Mathcad and I can't find out why. thank you, Thank you, 

Does anyone know how to download Mathcad (.xmcd) files from Windchill using Chrome/Edge so that they can be opened in Mathcad?   In Windchill, when I try to download a .xmcd file in a modern browser (Chrome, Edge) it automatically opens it in the browser in XML with the following error message displayed at the top: "This XML file does not appear to have any style information associated with it. The document tree is shown below." The workaround right now is just to use IE, however with IE going out of fashion we need it to work in modern browsers such as Edge and Chrome.     Thanks, Lawrence ------------------------------- I started a new thread because the only other related one I found is about 9 years old: xmcd-Files in browsers - PTC Community

Hi everyone!   I'm sharing with you this worksheet hoping it will help you extract moments, forces and supports reactions from the continuous beam (>=2 spans) for further beam design according the codes you use.   Please let me know if you find errors or want to improve the code (calculation time is around 1 min for a 5-spans beam).   Alvaro Gavilán   (edited 30-09-19: tolerance adjusted in 9.

This has been a nuisance for some time, but ...   If I evaluate a nested array, the matrix navigator seems to have little effect, sometimes nested arrays won't resize, and there doesn't seem to be a way to resize all of the elements at once ... not a happy state of affairs for large arrays.     Mathcad Express 7.0 worksheet attached.   Stuart

Hello everyone,In the attached file i have two programs r and q.program 'r' arranges the bars in one layer of beam cross section and 'q' is for the second layer.Here the number of layers are decided based on 'gqo' values.If they are positive, one layer of the bars are sufficient, i have to repeate the proceedure until it is positive (which means i have to arrange the bars in several layers).How can i automate y1....yn, d1....dn, n1.....nn, so that one program is sufficient to give the results for the bars in several layers. (y1,y2), (d1,d2), (n1,n2) belongs to first layer, (y3,y4).... for second layer, (y5,y6) for third layer and soo on.Attached mathcad 10 file.

Hello, I saw the older posts from 2013 and 2011, I think it is time to rethink and provide business and institution solutions to alternative operating systems. I've been working on moving all our functionality over to Linux as a cost saving and security measure. And MathCAD is being a bit of a thorn. I have not been able to install it through Bottles and SMath is neither on Flathub nor on Arch yet and we have the MathCAD licenses already. I have colleagues at other companies also working on moving things over. A lot is up to software developers to do the last support part. As we already want to use the software. Alvast bedankt. ps the KBA is ridiculous, having to login just to be informed that there is no support. CS328285

I have the step by step hand calculations for this type of problem but I really would like to learn the ptc Mathcad analysis for it and somehow the ODE Mass Spring problem doesn't help me make the connection. Could someone please help get me started with this?

HI,Could someone explain to me how to calculate the summation operator? I have attached a picture where you can see my formula. If I understand correctly, my condition formula should work like this: 0.1 + 0.2 + 0.3 + 0.4 + 0.5 = 1.5. However, Mathcad only gives 0.1. What am I doing wrong?

is there a way instead of writing all these qcza ( x ), I write just one variable that represents them all like  qcza;in and still get the same plot something like this   

Hi,Why is my answer unit not in Volts (V), and how can I change the unit? 

Would someone please tell me why when I enter unit for the vectors, it doesn't like it? I watched this video Assigning Units to Vectors and Matrices in Mathcad Prime (youtube.com) and that's what I'm doing. Thanks, 

Hi,         These curves are displayed best by using logarithmic axes.   The plot result should look like below: I am interested how to put that Rg/Ri on each graph.    

Is it possible in MathCAD to solve for a variable as I have shown in the snip?  I've tried different ways but cannot get it to work.  But I am also very new to this program. I want to solve for ΦVn.  I know my limiting capacity and the geometry of the weld to obtain the weld properties.   

A big hello to everyone here, I'm looking for a little program that receives as parameters only a square matrix of alphanumeric elements and a symbolic element to search in it. The program must return the row and column indices of the element searched. Is anyone able to make it? It seems simple to me. I thank very much whoever wants to do it.
