Mathcad

I use matchad prime 8 and for some reason this row operation doesn't work I can't seem to figure out why 

Hi All, I set up an solve block looking to solve a few equation, however the no solution can be found in solve block but when I use root fuction, I manage to get some answers. What have I done wrong? Can anyone spot the problem, please help. Also how do I get rid of the NaN number i.e. 0.6i on some answer in the root function.       

I am trying to find the efficiency of a 3 loop system. In order to find that, I need current equations of all the loops from which I can extract power of the circuit and eventually efficiency of the system. The solution I get is way too lengthy, I tried even manually to simplify them but had no luck.Please help!  

As shown above I have created an table with formula but I want to show the values rather than just formula. please help.Thank you in advance.  

 Hi, I am trying to create the table for wind pressure on various face of the building for various pressure coefficients. the formula are shown in the header of the table, Kindly help me to create on such table as in excel where the value will be calculated based on the formulas and how to retrieve a specific value from the table.Thank you in advance for your kind help. 

I'm trying to create a summary table at the end of a worksheet where I need the values of variables previously defined to come up instead of the variable name: 

Hello Everyone, I am attempting to write a 'RowSwapper' function in Prime 8. Essentially, I have a matrix 'A' in which I need to replace certain rows that are present in another matrix, 'B'. The function should take the following arguments: RowSwapper(A, B, "label"). It should generate a new matrix, called 'A_Swapped', where rows are swapped only in instances where items have the same ID (column 2) and where label="LoadCase4" (column 5). However, the function I've developed isn't ideal because it relies on matrix 'A' having a well-defined order, and that matrix 'B' maintains the same order per unique ID as they initially appear in Matrix 'A'. Furthermore, it only includes load cases equivalent to "LoadCase4". Additionally, it's time-consuming in terms of computation.  Screen shot of Matrix A and B:Desired Output Please note that I don't currently have access to Prime 9. Feel free to send me screenshots of the Prime 9 solution along with the file, which I can op

As shown above when I tried to linear interpolate the D values corresponding to h/d values of column 1. It is showing following error, Kindly help me.   

Hello, I have some difficulties to plot on a XY axes system, the efficiency of a voltage converter. I want to have on the x-ax the output current in Amps, and on the y-ax the result in % for a specific switching frequency value.The error that I got is related to the fact that the variable from the x-ax is undefined.Could you help me please to understand what is wrong? Thank you!  

 Hi, I am calculating mean wind speed at variable heights (ze) as as shown in above function.Now I want to create a table with variable heights say 10m, 15m. 20m and tabulate the corresponding wind velocity, so that i can reference it any where in the calculation and I also want to know how to extract exact data from table with the variable say like lookup functions in the excel.  

The only way I see to do it is to clear each variable individually ..... clear (x,y,z,....)  That can be a lot of typing in a large sheet and you might miss one.  I've had a few situations where I'd like to just clear everything and have a section of my worksheet act individually without any worry of using prior values but without having to relabel everything.    The documentation doesn't point to any solution, but I know there are occasionally undocumented techniques.Thanks,

As you see from the above snips the zmin is extracted from combo box of terrain category but is not recognized in the cr(ze) program.    

 Would be nice if Mathcad Prime included internal routine for the Schur and Jordan decompositions of a matrix.Has anyone developed a Mathcad Prime routine to return the Schur and Jordan decompositions of a matrix? Thanks for any help.

This is a text with tabs: Tab1 text Tab2 text text Unfortunately, it is not possible to write the right text in Prime 8 exactly below each other as a column.------------------------------- Translated from German to English using google translate. Translated by vnamboodheri on 19-01-2023 at 14:37 hrs.-------------------------------Das ist ein Text mit Tabulatoren: Tab1               Text   Tab2     Text    Text Es ist leider nicht möglich, den rechten Text in Prime 8 genau untereinander als Spalte zu schreiben.

The percentage operator in the result is getting scaled to 1% after converting it to prime. Is there any way to avoid this ?    

Hello communityI request your help please with the following problem:I need to run a for or similar loop that allows me to build a 1x (2N) array, where N is an input value.That is, the array will always have an even number of rows. On each odd row the routine should place "Px" and on each even row the routine should place "Py".   Thanking you in advance for your help  

Hello, I would like to export a complete matrix from mathcad prime 8.0 to an existing Excel file and in a specified range of cells. While reading through some older posts on this topic, I got the feeling this shouldn't be too hard. I am, however, completely new to VBA. For now i have the following lines: Sub ExportMatrixToExcel()Dim MCApp As Ptc_MathcadPrime_Automation.ApplicationDim WS As Ptc_MathcadPrime_Automation.WorksheetSet MCApp = New Ptc_MathcadPrime_Automation.ApplicationMCApp.Visible = TrueMCApp.Open ("E:\Mathcad\test.mcdx") From here i would like to export the matrix in the mathcad file to my Excel file. The dimension of the matrix is 5x5 and let's say i want to place this matrix in Excel starting at C5 and ending at G9.  Is somebody willing to help me with this with a general example?Thanks in advance     

Dear Sir/Madame,I would like to download my PTC Mathcad Prime 3.1 Student Edition – Perpetual License but unfortunately the 'BEGIN DOWNLOAD' button does not work. Please, forward me the instalation file. I would like to install application on the another computer. I do not know what to do because contact with PTC is so complicated. I paid for product and I cannot use it. Please give emails to your support.

Hello everyone, I'm encountering a problem with the attached Mathcad Prime 8 where the custom function MaxRecords(M) isn't yielding the expected results when reading imported data from the attached RAW DATA.xlsx. The input matrix "MaxT3" passed to the MaxRecords(M) function, comprises five sets of results for each ID where there is a total of 289 IDs. I need to extract only the records with the maximum resultant force FR (column 10). The result from MaxRecords should have only 289 records, but it's currently delivering 1445 records (289x5). Could you please review and let me know where the issue lies?.  Also, the resultant matrix of maximum records should keep the same order as the matrix MainRunT3: I tested the MaxRecords function with a smaller data set and is working fine (see snapshots below of the smaller set raw data and the corresponding MathCAD results): Finally, please let me know an easy method to disconnect a large matrix from its formula.&

Hi ALL, How do you avoid unnecessary parentheses that Mathcad applied to each complete expression automatically? It seems to me that it is one of the first information to be learned but it escapes me at present. How do I? Thank much. 

             

L.S., being on the side of business, I have Prime 9 as free available. I would like to open some older files and need a running Mathcad 15 to convert them, as I have been told.If anyone can do the conversion for me, that would be great.You find the files attached.Gerrit van der Graafg.vandergraaf782@gmail.com    

Hi!Assume the following simple equations, which I want first to define x=b+5 and later solve the second equation for b.How can I do that?  The same question when we add units as well. Here, I think I need a symbolic variable (a) defined first and then solve Z for a to find the a.Any help is much appreciated.     

My Worksheet Converter in M-C Prime 8.0 for some unknown reason got grayed out and I cannot access it.A note says "Worksheet converter is not installed. Run setup to add the installation."Can somebody tell me how to do it. I tried to search for it but I could find nothing about running setup and reinstalling the Converter.

Please see attached Prime 9 file. I want to format graph to look like :
