Mathcad

Good Morning, I have encountered a problem solving a symbolic equation using Mathcad Prime 11.0.0.0. I try to evaluate the derivative of function using keywords from Sybolics (Operators and Symbols).The error is: "More than one independent variable for keyword solve.What I try to do is to find when the derivative of the function is equal zero. To find max/min of a function.One variable in function f(x) is x. The rest is defined above. So I do not understand what the problem is here. Variable x should be in metres , from range 0 to 1.Please see below. Also file in attachment.   What did I wrong? Is there a better way to find a solution? Anyone could help? How to do it properly? Kind RegardsKarol

I made my homework in mathcad 15 in uni lab and tried to open it on my pc, since I have mathcad 11 prime I tried to convert it with built-in converter and I got an error. Attached both XMCD and Log(XML) file.

How can I determine the maximum absolute value of a vector, but have the result appear with its corresponding sign?. Thanks to the community for your attention. 

Saludos comunidad, tengo un problema con la solución a través de un bloque solucionado para determinar los diferentes valores detallados.(PTC Mathcad Prime 10.0.0.0) El problema que tengo es que el resultado para cada fila de la matriz g es el mismo, y no debería ser así, específicamente  Gracias por su atención

Helo folks!Please see the attached file.How can I filter the range variable or vector so that it basicly creates a new one but for values greater then, let say 9 (like in the file attached) it returns 9 for all remaining values in the range.Please help.Thank you.

Hello everyone,I am trying to convert an old calculation file (in PDF format) to the latest version of Mathcad Prime. There are a few functions that I don't fully understand. I am attaching the PDF and the Mathcad Prime file for reference. Any help is appreciated. Thank you!

I am trying to evaluate the sum shown below. I get "This array index is invalid for this array" but I don't see it. I would have thought that if the upper value in the sum is less than the lower, MC would give zero. That is not the case. Maybe this is the problem but, if so, I don't see how to solve it. As always, any help would be appreciated. 

Hello everyone, I hope you are doing fine!I recently calculated wave theory selection using Mathcad Prime 9.0.0.0. I'm curious, is there a way to determine the region automatically for given points? I want the function to return "Linear/Airy", "Stokes 5", "Stream Function 3", etc. based on the chart.Does anyone know? I attached the full calculation below.  

I'm using MathCAD 9.0.0.0If ......and......then why does......when it should clearly be "50" layers in the base?My program is attached. Thank you,        Brent

I was just playing around with the function format to see if I could create a readable, compact form that displays the values of variables in an expression.   To do this, I wanted to use the Unicode character point 10 or 13 to generate a newline.   This worked in Prime 10, and I'd previously used it to create string justification functions, such as:     Mathcad Prime 11 has broken this behaviour.  I now get:     Why did PTC do this?  Is it a bug that got introduced, or was it deliberate?  If the latter, what benefits accrue to the user that outweigh the loss of functionality?   I've been requesting more sophisticated strings since before Mathcad Prime was developed and throughout its entire existence—for example, HTML or RTF.   Taking even such a limited capability away is irritating in extremis.   Stuart   @DJNewman , @amcgough   

Is it an error in Mathcad Prime?

There is a problem with Prime8 in the way it assigns parentheses when differentiating functions - for example: This of course looks correct - but if you  paste the answer into another equation - Prime8 erroneously assumes the leading differentiation applies to the remainder of the expression i.e.:  So Prime8 should have given the original differential with parentheses assigned as follows :  When deriving complex partial differential expressions  (@SP_9781969) this defect is a problem. The workaround is to manually correct the results at each stage by inserting brackets at the right place - however, even this can be tricky as  Prime8 conflates everything together and won't allow brackets to be inserted around the correct terms - so you have to cut and paste - and exercise that itself can inject errors further errors.  

Tested a solution block in Part 1 of attached with scalar variables. Works just fine.However, when I change to column vector variables in part 2, I think that my element-wise array multiplication and division is not working out.Suggestions for correcting part 2 will be appreciated.Using Mathacd Prime 10.0.1.0.

Hi! First of all... I'm kind of a n00b in Mathcad so please bear with me. I am writing a sheet thats supposed to calculate resisting moment in concrete slab using vectors and matrices and some code blocks. Or I didn't write it... Google AI studio did 😕As you can see in the attached image and the attached file I', getting "Undefined variable" when trying to visualize the matrix, wich accoring to Google should work. Further down it will result in i a table the for export to Excel.As I'm pretty lost, and Google cant fix it (neither do ChatGPT) can you spot the error(s) 😉 I'm using Mathcad Prime 10.0.1.0 Best regards,Fredrik 

Hi I would like to understand the solutions for the below queries raised by a user. Appreciate your help. Aligning of text boxes and formula boxes.Array for various values for same function.How to use if command to state design is safe or not. Usually, we need to green highlight if the design is safe and red if not safe.To add graph for considering various values and array and another function. Like SFD, BMD etc.Setting company standard template for page formatAdd calculation template for similar repeated calculation.Drop down menu similar to Excel.We are finding difficulty in adding unit as %Can we import more symbols such as “therefore”; “similarly”;How to add border for text box or important formula box.Adding table for various values for one function & how to Vlook-up from it?ThanksNaresh

I attached my MathCAD 9.0.0.0 file.The correct answer for the 1st part is...If , I get the wrong answer...If I remove the "min" units , I get the right answer......I don't know why it's doing that, but worst case, I can live with that. The 2nd part answer should be...However, it won't calculate the answer...There might be a problem with the variable Ct because before there was a box around just that variable in the equation. Now the box is around the entire equation.    

Hi there , I have created this combi table ( the sheet is attached ) I want to use the result in a easy program .. like if the shape is square use this equation if not use the equation for round piles can you help me to do so? the easier program the better Thanks in advance   

I'm writing a report in Mathcad Prime 11 and have an Excel file as appendix at the end of the Mathcad worksheet. The Excel file has been generated from within Mathcad and uses inputs defined in the body of the Mathcad worksheet.What I would like to do is globally define an output from the Excel file so I can use/reference it in the body of my report higher up in the worksheet than the Excel file.I have no problem defining an output and using it in the worksheet BELOW the Excel file, but I would like to know if there is some way of defining an output and using it ABOVE the Excel file. Is this possible?Thanks 

I'm trying to stack two matrixes into a single text file.  Screen shot of what I would like is in the file.  Between the two files is a user defined combination of letters and numbers.  obviously, the top For loop is not working right. There also seems to be an extra space in front of [INFO] in the text file. And there is an undefined character at the end of each line of the top matrix.  

Hello everyone, Why is the mean function not giving me the average of my data? Am I doing it wrong? 

HelloI am a newbie with regards to MathCAD in general and the Checkbox functionality in particular.Running MathCAD prime 11.0.0.0I just wonder if there is a convenient way of generating an array of checkboxes  so that one make it simple to can "click on all that apply".Hope this is not too trivial..RegardsHallvard

Does anybody know the correct code for reading out matrix content with JScript in MathCAD when loading it through the API?  This is the MathCAD simplified example in MathCAD Prime 11.  This is the code in the button: Reading a matrix value like this works excellent when loading the Matrix as a normal input variable without API. Other API functions works fine, like for instance Worksheet.Output.GetValue("EampleNumber").RealResult      

I have the excel in that some type are there for e.g. frame size and its W,A etc. is there, I am trying to create this in Mathcad when I type the frame name it will automatically shows the all parameters related to that how this is possible in Mathcad for this I am using lookup function if anyone done this in past or have any suggestion how to achieve this pls comment on this I also attached the sheet and excel file.

I have a mathcad 14 file made by someone else and I am having difficulty to get it to calculate properly I select 'Calculate now', 'Calculate Spreadsheet' and 'Automatic Calculation' and none of them actually seem to calculate. For a colleague it seems to work and we were unable to find the reason. for example, my colleague gets a plot here perfectly and I get this:  what could be causing this? the file is attached
