Mathcad

Hi All, I have a question about the curve plot. Attached is an example I want to ask. Can we have the control of the curve in the plot, by only letting it show in a specific range? We can do it in the math function, by including some conditional setup. But if we do not do the conditional setup, can we still place the limitation in the curve plot?

Hi!I would like to send this data to Creo, to create a 3D Model, is there a way to do so?Many thanks,Ioana

I use CurveExpert (version 2.4.0) for getting an initial idea on what is the best fitting model for a data set. However, when I want to use then the proposed equation in Mathcad I do not get optimal results. In the rational fit I am completely out of range while in the sinusoidal fit my R² is lower. I assume that I am not familiar enough with all fitting possibilities within Mathcad 15. So I would appreciate any help as I would like to improve my skills or to understand why the results in Mathcad are inferior to those of CurveExpert. I have added 2 worksheets to demonstrate the issue.

Hi, I'm trying to solve fairly simple equations element by element in an array and from what I've read here it looks like a For loop calling a solve function is the way to go.  I know I can't have a Given/Find in a For loop and have to write the function elsewhere and call it from the loop, but I'm having trouble getting that to work  I found a lot of discussion on here about this, but none that I have been able to implement.   I have attached both the file I'm working on and a simple example of what I'm trying to do that I think will be easier/faster to work on, then I can modify the actual file.I've been tasked with converting some calculations from Excel to Mathcad 15, and I'm new to Mathcad so learning as I go.Thanks much in advance for your help.

Hello MathCAD Comunity!The company I work for are having serious issues when combining MathCAD 15 with Excel 2013.We use excel components for various tasks throughout our MathCAD files as follows:Section Titles, (excel components used to display title headings, allowing the numbering to be automatically updated)Figure Labelling, (excel components used to display figure labels)Excel components used to display ‘Utilisation Ratio’ (calculation that shows calculated values versus allowable values, ratio is then displayed as a value, less than 1 = pass, more than 1 = fail.)Excel Tables used to allow numerous Utilisation ratios to be displayed together for comparison.We have numerous problems which I will list below however on the whole they can be described as making mathCAD at best unresponsive and at worst unstable to the extent that doing any work become nearly impossible. The most frustrating point is that PCs with previous versions of excel installed work absolutely fine.The specific i

hello,i have problems using Mathcad 14 on different workstations in our company: when i open a mathcad file on a certain Workstation, which is created on aother Workstation, the page setup seems to be somehow different. the pages are larger or at least wider, although it is showing the same size on the ruler (DIN A4). Additionally it seems like the paragraphs and especially the pictures have been pushed together vertically. so they are partially located on top of each other. all the other work stations in our Company work fine, except this one. i guess it has something to do with the page or printer Settings. hopefully someone can help me.best regards and thanks in advance,Stefan

Been using Mathcad for 8 years.  First version 13 and now 14.  Throughout the  years, I have had a problem with the software....sometime when I print, it would "short sheet" me, i.e., it would make one or two sheet divisions shorter than all the others which meant I would have to rearrange every sheet, leaving out the short sheeted sheet.  Something different happened today that is similar, but it went in the opposite direction, it made all the sheets longer than normal.  I should have posted this a long time ago, but I have grown weary after this "new" issue today.  Has anyone ever had this problem and do you know how to keep it from happening.Thanks

HiHow would I solve the following problem on cable lengthThanksTwo cables, both with cross sectional area 5 mm2, are connected in parallel across a common DC voltage of E = 36 V.The resistivity of Cable 1 is ρ = 17 x 10-9 Ω.m at 20 °C, while the resistivity of Cable 2 is ρ = 28 x 10-9 Ω.m at 20 °C.Cable 1 is 1641 mm in length.If 44.9 % of the current passes through Cable 1, determine the length of Cable 2.Assume the ambient temperature is 20°C.

what i want to do is making a loop, which can do an iteration work automatically.In this function, i put the initial valueand by using an Minerr optimization, it gives final values(which i defined as Newvalue)and what i need to do is iteration workso reusing this Newvalue as an initial value.for example, if i put n=3, it should mean it iterate 3 timesfor that i tried using an While loop.but i think this is not right..because it gives same result eventhough i put different value of n.can you help me with this problem?

Hi,I am trying to write a simple command to create a matrix with two columns one of which would display a value of the governing shear force and the other with text (as in the screen below). When I loop it, the result is not what I intended. I would be grateful if someone could indicate what is wrong. Regards,MK

Dear all,I have this very simple code that gives a different result with the same input but in a different worksheet. I can't imagine what goes wrong here. Below you can find two snippets of the code:                         Thanks for your help

Hey guys, sorry in advanced if this is an ongoing discussion here, I tried hard to find something similar but I couldn't.My problem is: I already have an mathcad file doing all the calculation i need with the necessary inputs as thickness, width, etc. I would like to be able to change these inputs using values from an excel spreadsheet.I already figured it out how to do using the SetValue function on VBA, but the problem is that once I close the mathcad, this modification is gone. I read somewhere that this kind of manipulation is only possible changing the XML file, is that correct? Do you guys know if there is a different and simple solution for the MathCad 15?Thanks in advance!Denis.

Hi, In Mathcad 15 the attached commands dont cause error but it seems Mathcad Prime 3.0 flags error. Any idea about why is it giving error on Prime 3.0?

Hi all, I have a simple example attached regarding my question. If I have a variable, which depends on the input condition. Can I set the text color or highlight of the output, to represent different input conditions? In this example, if my output displays "RIGHT", I want to set it to green; likewise, if the output is "WRONG", I want to set the text to red. Would anyone teach me how to do it? Thank you!

Hi..As when i used Mathcad 15 there is separate mathcad libraries for Mechanical, Electrical, Electronics, Civil etc are available.But i am not able to get it in Prime 2.0 so please can you suggest how to install libraries.Regards,Prashant Pandarkar

I found an (old) pdf file on the web that uses a 4 parameter logistic fit for immunoassay. Unfortunately I must be overlooking something as it does not work in MC15. Are there more elegant ways to do this 4 parameter logistic fit?Thanks in advance

hi all,i'm trying to insert an image into a prime 2 worksheet.  i can copy/paste it or use the "insert image region"  tool then browse to it.  many different formats show up in the sheet properly (jpg, png, bmp, tif, gif) but when i try to save, i get an error. how do i get na image into the sheet?

Hi, for some odd reason Mathcad 15 is not pulling from the "enx array" despite that array having values in these indicies.  Is it because the derivative? Anyway I can fix this?Thanks

hi all, i'm using prime 2.  when i smooth some data with the movavg function, the resulting data is offset by the size of the smoothing window.  in fact, even the helpcenter example on using moving average to smooth data shows this resulting offset!  but with no comment.  attached.is this a bug or am i using movavg wrong?

I only want to run Mathcad 15 (I am running a free trial version). My question is : PTC has only mathcad 15 version to sellor I have to buy all included version Mathcad Professional?

I just installed Mathcad 15 and I also bought Roarks worksheets from PTC installed in my computer. But all XMCD files in folder shown as Adobe , i can't open them when I click them, and I only open them in Mathcad 15 environment. I want to open them directly when I click a XMCD file, how can I do?Thanks,Ling

Hello dear PTC community,I am very new in MathCad and strugle with it a lot.If someone could help me to create table to calculate Total K like it is in attached excel file I will be very grateful!Many Thanx in advance!

In reference to this document: Minerr/nonlinear optimizingYour equation for Function is wrong. For a least squares fit the error function should be the square root of the sum of the squares (or just the sum of the squares). You have the sum of the square root of the squares, which is equivalent to the sum of the absolute values. See my Function2 for the correct error function.Having said that, the best way to fit a function to experimental data is to create a function that generates the vector of residuals: see my Function3. Feed that directly to minerr, and use the Levenberg-Marquardt option.Minimizing Function gives an error (i.e. Function2) of 1721, 311, or 133, depending on the algorithm usedMinimizing Function2 gives an error (i.e. Function2) of 1628, 109, or 100, depending on the algorithm usedMinimizing Function3 using the LM algorithm gives an error (i.e. Function2) of 261I'm not sure why the last option does not give an error as low as a couple of the other options, except to
