Is there a way to test if a variable is a matrix in Prime 2.0?I'm writting a function that uses the function vertflip. I want my function to accept a scaler or matrix, but vertflip only accepts matricies. So I'm looking to do something like...vertflip(if(ismatrix(M), M, [M]))

I have some questions. I have uploaded the Mathcad 14 file and here is a image of it.Show expanded function without replacing the variable per its values.Result in degrees. it wont let me select any unit. Only positive result. If I add: assume θ>0 the solve fails! Why?x-axis (θ) in degrees, not rad. The range is set from 0°-90° but it is still displayed as rad!

Hello, I have a spreadsheet which was developed by anohter firm and was made to use. I was able to make the dit to the spread shett the way i wanted it but when it came to the results at the end, I am not able to edit the already exisiting table (matrix) that is provided by the developer. Can someone please help me on how I can edit the "Analysis Results" on the last 2 page of the attached file. Thank you-NavP.S: I am trying to edit/delete few sections in the "Analysis Criteria" in last 2 pages.

Hi,I am having trouble looping through this program. I am basically taking the FORTRAN approach (attached) and trying to implement it into MathCAD 14. I am confused on how to make some of the change over.Any help would be greatly appreciated.

hi, guyshere is my problem.I want to connect pro/e with modefrontier by using trail file. So I first define some parameters in pro/e. However, in the trail file, there shows no parameter name just some numbers. Does anyone know how to modify trail file, in order to define parameters?here is a part of my trail file:~ Command `ProCmdMmParams` ~ Activate `relation_dlg` `ParamsPHLay.TBAddParam`~ Key `relation_dlg` `ParamsPHLay.ParTable` \5505140 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4718696 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \524296 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \524296 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4259937 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \5111918 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \4653159 ~ Key `relation_dlg` `ParamsPHLay.ParTable` \3211313 ~ Disarm `relation_dlg` `ParamsPHLay.ParTable` \2 `new_added_row` `name`~ Activate `relation_dlg` `ParamsPHLay.TBAddParam`~ Key `relation_dlg` `ParamsPHLay.ParTable` \5898362 ~ Key `rel

Hello Community,My xmcd-file doesnt open anymore. Mathcad shows me only the message, that the file is destroyed. The error message give no further information what is wrong with the file. See the screen shot attached.I am using Mathcad 15.What do I need to do, to be able to use the file again?Thank you very much for your help in advance.Harald

When I create a 2D Plot and zoom in, how do I zoom back to original plot size?In Matlab ther is an option "Zoom back to default size", is there something similar in MathCAD?Speaking of graphs, I had looked at the old post regarding saving graphs to images in MathCAD 14, and the verdictseemed to be "click on graph, copy and past in Paint or similar". Any better ideas for high resolution plots, please?

Good DayI’m a bit new to Mathcad Prime 2.0, and I’m having trouble graphing the Weibull distribution curve. I’ve tried numerous times with no luck and all I end up is with a vertical line. Is it possible for you guys to take me step-by-step in making the curve?Thank YouDavid Escobar

I'll try and explain this the best I can and also the fact that I don't know if Mathcad can actually do what I requireI'm trying to produce a 2D graph from two varibles which can change. The graph is for a design of a beam where:-The load applied to the beam is known.The moment capacity of the beam is known.However the span can changeThe adjacent beam centers can change.The unity ratio of the beam passing <1.0 and failing >1.0I've attached a what I think it should look like and the formula. I believe this may require some sort of programming or I'm not sure whether Mathcad can actually do something like this.Please bear in mind I'm using Mathcad 14Thanks

Hi, Collab --I know that this is a long shot, but I thought maybe worth a try...A few months ago, seemingly out of the blue, we became unable to save Mathcad 15 files (xmcd, xmcdz, mcd) to one of our network drives. I note that rtf from MC15 and Prime files are no problem. It is also possible to copy MC15 files onto this network drive -- we just can't save them from MC15. The specific error we get is, "Disk full while accessing M:\filename.xmcd". The disk is most certainly not full. I also note that so far this error is 100% reproducible -- we have not seen a file, user, or workstation from which this error does not occur.Like I said, a long shot -- it could be MC, server hardware, server software, any number of things -- but has anyone else ever come across this?Thanks.Matt

I am decent with mathcad for simple calculations but lack understanding of the programming. I am really wanting to get a bit better but don't have any teaching and/or references. I thought at least this discussion board could be a great place for me to get help and tips.For this problem I have 2 vectors each containing 100 values. What i am looking to do is subtract each and every single value in each vector from eachother. I think I may need to use some sort of looping routine in order to accomplish this but I don't know how. Maybe there is another way that is better. Sheet is attached with comments in red. Any help would be greatly appreciated. Also if anyone could point me in a good direction (books, etc) to become more familiar with creating these types of routines (for loops, nested for loops, etc). That would be greatly appreciated as well.

I have a Mathcad document along the lines of:r:=10mm---------Many equations using r and other variables.---------stress = 50 MPaIs there a way to find the value of r that gives the minimum stress without totally re-writing the document?I know this can be done relatively easily for discrete values of r by using a vector but I'd ideally like to do the equivalent of an Excel goal seek.

To allI am thinking about a possible mcad sheet for an hyperelastic material ie a rubber. Attached is a typical curve for such material.I would like to predict the displacment (of some quantity, maybe stress) knowing the total force to be applied. I am not sure so will be happy to be corrected but is this a non linear problem (gien the shape of the curve)?Known total force to the applieda (non-linear) relationship between say strain & stressFindThe final "state" once all the toal force is appliedI haven't got a clue where to start. Does the probleme require some kind of iterative solver?Am I overthinking the whole think?Any suggestion is welcomeThanksRegardsJXB

I am using Mathcad 15.0.0.436.I am also using an older file that was created in Mathcad 14 with minor modifications to some of the inputs.The file printed fine before I upgraded to 15.I have full page text blocks that wrap at the margin to create multiple lines of text.When I print the file out, some of the text 'disappears' past the right hand margin.I have tried changing margins, and changing printers, but to no avail. This also shows up likes this in the print preview screen.I am not using a speciatl text font (Normal, Arial 10), so am clueless as to why this is happening.I use this text technique a lot and it will be very burdensome to manually change every full-page text block so that it is not full page and also fits on the page.Is this a bug, or is there a fix for this?Thanks

I prefer to work with a black bacground. Anybody knows how to set default font color to white ( in MathCAD 14 ), please?

Hello All,My data has several peaks and I want to fit Gaussian function to each one to obtain the position of each peak's apex. Could you please let me have the idea how to do this? My program should find the peaks and fit the Gaussian to each one.Thank you very much in advance.Payman

Hello All,I am using Mathcad 14. Unfortunately the function "localmax" is not working with this version. Do you know how I can add this function?

I have installed mathcad prime 3.0 on my computer but I don't know how to download mathcad 15 with the license (I need to convert some of my files). Can anyone help me with this?

Hello All,I have two oscillating signals. I want to find the position where1) The signals maxima coincide with each other (the best match), 2) The signals minima coincide with each other (the best match), 3) One signal's max coincides with another signal's min.Such points are indicated on the attached graph. Would you please help me with programming this step? Thank you very much in advance.Payman

Would someone from confirm or correct my understanding of the missing features below, and let me know which have been reinstated on Prime 3.0?1. You can't change font size for math expressions.2. You can't wrap a math expression to a new line.3. You can't spell check.4. You can't print preview.5. You cant add title and axis labels to graphs.

HiCan I read results from another mathcad file?If yes HOW?Thanks
