Mathcad

Hi,  I'm installing Mathcad Prime 5.0, but the "Application Selection" Section is empty and i dont know why?

Greetings! I am solving a pair of odes using mathcad built in odesolve function. I want to know if there is a way to alter the default tolerance and number of iterations of this function. Because when i solve it its gives a statement that solution is not converging to a solution refer to Help.   Thanks.

Hi everybody,how can I solve this equation?   I found problems because of the derivative function squared. I need to collect the term derivative not squared...Thanks Bye

Hey   when i definition a value with a unit and want to recall it later. It alwas shows the SI unit instant of the unit i use when i definition.   Anyway that mathcad  can recall with the unit I did definition, so that i dont have to do it manual everytime ?

I am performing some martrix algebra.When I ask Mathcad what cos(pi/2) equals it says "6.123X10^-17". How do I get this value to revert to 0, which is the true value?Thank youJamie

Hi, I have several CSV files that contain 10,000 rows by 16 columns in a .CSV generated file as seen in the attachment. I want to execute some formulae on these data so that I can open it up and be able to run the formulae for each CSV file. How can I make this file to work?   Originally I had to convert CSV file to xlsx and then read it as follows.   [num21 txt21 numtxt21]=xlsread('R21_08S','B2:Q10001');   However this is too tedious and I would rather read it as:   [fNameDatai,pathNameData]=uigetfile('*.csv', 'Select the DATA file','Multiselect','on');if ~iscell(fNameDatai),fNameData{1}=fNameDatai;else fNameData=fNameDatai;end   so that I don't have to convert CSV file to xslx and be able to just select the rows and columns I need.   Thanks   Thanks

In the attached Mathcad prime 3.1 worksheet (along with screenshot) I've graphed two vectors in an X-Y plot. Is it possible to create a function such that the user can type in any value for temperature( within the highest and lowest value) and receive the temperature back?

Hello,   I have a problem with importing my MathCad results into the Excel component. I have two variables and I want their summation (one a range hhm,  and the other one is a scalar hm). I can get the summation outside of the Excel component, but it's not working inside the Excel component.  Any tip is really appreciated. Thank you! Helya

What is a Range variable?This is a variable, without which it was impossible to do someone in old-old versions of Mathcad (Mathcad 4 I think but not Prime). There was no programming and technology for QuickPlot in this versions. Now, we have programming and technology of QuickPlon. But we continue to use the range variable according to habit, for convenience. But this sometimes creates some problems (one example here). The range variable is similar to the vector and some Mathcad users try to apply to the range variable tools intended purely for the vector.My question is this!Can you show me one Mathcad sheet where we can not do anything without a range variable? One little example:

Hello erverybody,   I want to open a *.xmcd-file (which created by Mathcad 15) in Mathcad Prime 5.0, but failure. PTC Mathcad Prime 5.0.0.0 XMCD, MCD Converter can not convert too: error message is "Mathcad 15 M010 or higher is required to run the converter.".   And after each converting, I must restart the converter. Is it normal?   I used the data in xmcd converter as exercise, but converting was also fail.   Could you tell me what are the reasons for the two question above? Thanks for your antworts.   Best regardsSun

Whenever I convert a Mathcad file to PDF format by printing to Adobe PDF, the content of the pages get displaced downwards both in the pdf file and the original Mathcad file. This happens when I have many pages in the Mathcad file. Is there something I'm supposed to set in the printer settings to prevent this from happening?

Hi MathCAD 15, I use references a lot with success but yesterday I met some bug for the first time. My file became big and I decided to split it into two parts - processing and postprocessing. I created a new postprocessing file and insert processing file as a reference at the beginning of it. I post-process (output) variables of processing file and meet several variables which are not defined. I checked them at the end of processing file - they are defined. Has anybody had the same problem with references?  

Hi, i am new to Mathcad. I am having difficulty recreating the model described in the attached study. Since there are so many equations, it is getting very overwhelming. Any tips on how to get started would be highly appreciated.   Regards

Hello, I want to set a function of type y = A1 + A2 * exp (-X / A3) + A4 * exp (-X / A4) to my data. I need to find the values ​​of Ai. I tried to use the genfit function and an error occurred. I saw in the forum that there are several tips, but I am a beginner in Mathcad, and would like some help. Attached follows the data I would like to perform my function. Thank you

Opposite to older MC versions PRIME has no possibility to compare files in two windows arranged vertically or side-by-side. Is this correct?

Hello to all,   I am looking to see if anyone has any experience in using the BS 7910 standard or can simply pull me up on my error in the attached.   Within the standard there is a mathematical definition for a pass fail curve (where the variable Lr is plotted on the x axis).   Toward the bottom of the attached I have inserted an exert from the standard, my attempt to define this, my result and what I am expecting to see.    Obviously something is not quite right.    Any thoughts or hints welcomed as always.   Thanks,   Andy   PS using MCP3    

The differential equation solve block is giving an error regarding too few initial conditions. I have 3 second order equations and 6 initial conditions. I cannot understand why there is an error?? Any assistance would be appreciated Thanks Ross

When exports pdf file from Mathcad with pictures and tables, it is seen that some part of table or image will be in one page and other part in another page. But in actual Mathcad file, I am keeping the the pictures or tables only in one page itself. When go for print option to get the .pdf file, all the alignment goes misaligned. It will be helpful if some suggestion can improve this situation.   Error case example follows,    

Because I use both numeric differential equation solvers and programming blocks, most of my Mathcad worksheets' outputs that I want to plot are in the form of range variables.  Is there a way to plot a Range Variable using the Mathcad 5.0 Charting Component?  If I set either the X or Y input for a chart component to a range variable, I get an error "The variable name for this input expression is not valid."  I tried including and excluding the range subscript in the assignment to X and Y and get the same error with or without the subscript.    Range variable plots work just fine using a normal graph.    Tom

I need to fit a curve like the one in the following picture: I think this is done with the statistical toolbox in matlab. I tried cure fitting in mathcad but i think it works here. I will attach my mathcad file. Can anyone check and see if the problem is with the low number of points or the one in the picture is using something different from curve fitting.

Hello, I'm having a problem in a routine I created to parse a data. I have a data, which is attached. I need to calculate the average values ​​that are close to the maximum and the minimum. After that, I need to average those values ​​and then subtract them. I made a routine that takes the values ​​close to the maximum value, but when I set them to a new table, values ​​that do not meet the established criteria are zero in the new vector. I wanted the new vector to have the ordered ones and that there were no valances that did not meet the criteria. The program is also attached.   thank you

In switching between working on my laptop and with monitors, I have had issues with inserted images and PDF snapshots adjusting their position within my Mathcad worksheets.  Is there a fix to this?  I believe that it has some thing to do with adjusting the screen resolution and also impacts when others use any template calculations that I have created.
