Mathcad

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?

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  

Is it possible to solve the ODE in attach? Thanks!

 I succeeded calculate multiply:But convert in vector "g" I cant do And quastion: Do mathcad have any method to calculate this?Like:     

I have made an attempt to extract the right set of data (column) from two different tables based upon the selection in the combo boxes, unfortunately it's not working as I want. Attached is my worksheet. Thanks for any help!   

Good evening,   I am having problems licensing my Mathcad 9! I am a student at a university in Austria, computer science branch, and got a product key from my teacher. I redeemed it at school, where everything still worked and I could use Mathcad 9 without any problems. But when I wanted to do my homework at home, my software was unlicensed. I tried to re-license it with my user + password + product key (the same one I used at school) and with the license file that was sent to me when I licensed myself at school. However, neither of these worked. When I want to activate my key at home with user, password, and license key I get this error (see picture in the attachment). When I am back at school and connected to the school wifi, I can select my license file and use Mathcad 9 normally.   Kind regards, Philip

Hello,My company is migrating from Mathcad 15 to Mathcad Prime 9.0. We have a number of Python scripting files that generate Mathcad 15 files by creating the XML data needed to generate and access Mathcad 15 files. In Mathcad Prime 9.0, it looks like the files are not purely XML data. There appears to be some sort of header and footer data, in addition to the XML data. Is there information on what the header and footer data is? Additionally, the Python scripts internal to my company just puts together a string of characters to generate the XML data. Would this work in Mathcad Prime 9.0? I need to convert the files to support Mathcad Prime 9.0, but it doesn't appear to be as straightforward as I thought.   

Hello, The Maximize function does not work properly in the following case - I need to calculate the worst case error in a current measurement circuit where x, y, z, y, v, w are the sources of error (resistors, opamp gain, offsets, temperature dependance coefficients) and a, b are the current and the temperature which I would like to be parameters so that I can plot later the worst error versus current and temperature. The Maximize function gives the correct answer - all variables saturated at their maximums only for CTOL=10^-9 - this is completely strange and unacceptable behavior! For CTOL=10^-10 the solution is erroneous and also for any other CTOL up to 10^-21: I guess these Maximize and Minimize functions are really nor working well with somewhat more complex examples which unfortunately are present in the real engineering practice! 

Hello,Why do I have 2 different values ​​when calculating the symbolic and numerical value for the same integral like below example? Symbolic calculation:   Numeric calculation:   Symbolic calculation first then numeric calculation:

HiWhen I have a collapsible area followed by a page break and I close the area,empty pages remain above the page break (see attached file with an example).I didn't have this problem with Mathcad 15. In addition with Mathcad 15 I was able to set page breaks inside a collapsible area, which is veryhandy option when the collapsible area is relatively large. To my understanding naming of areas is also missing from Prime... Any ideas how to solve these problems? Thanks.

I am installing Mathcad 14 from my installation DVD on a new PC. All went well except towards the end a window says, "The wizard is now contacting the PTC licensing server to obtain your license automatically. This may take a few moments." Then another window pops up saying, "The remote server returned an error: (403) Forbidden." What do I do now?   

Hi,i have a new laptop to work on mathcad but i can't connect to my user because i have to enter my license when i am hitting enter is says license is used how can i still connect to my user?  

Hello, why Mathcad does not find the maximum for this simple problem - it should be when x=1, y=1 and z=1 - in total f=2. For some reason x and y are kept to 0 even when the 0 is excluded from the range of search for x and y:   Thanks!
