Mathcad

I am trying to work out how to calculate all the paths from each cell in column zero to the end column. This is part of project to calculate the remaining strength in a material.  The matrix represents a grid on the material.  Each cell in the matrix contains a measured parameter at a location on the grid. I need to calculate the sum of all the paths available from each of the cells in column zero.  The path can progress one cell up or one cell down or one cell across.  It can never go backwards.   In the attached file is a grid of 5 x 7, with fictitious data.  In reality the grids are more likely to be 20 x 40.   I can see how to do it manually but I cannot see how to do it within Mathcad.   Any direction or guidance would be appreciated.   The system will not allow me to attach a file. "The contents of the attachment doesn't match its file type", which is nonsense because it is an mcdx file.       Thank you

I know prime plotting is lacking, but is there anyway to specify which variable a set is plotted against?  In this simple example I seem to need two x's, while it is perfectly happy to stack up the y - provided it comes last.  Can I show a single x and single y on the abscissa?  4.0 attached. This is what I have (2 x's): I'd like this (1 x): (paint mockup)   Thanks,

Can anybody point me to my error. I can't get a decent fit for my data; see attached MC15 file.   Thanks in advance   Raiko   P.S. For some reason the website does not accept the MC15 file claiming that "...the contents of the attachement doesn't match its file type." henec, I've added a pdf.

Hey , can anyone help me with that failure in my code? I want to understand this.   Best thx , Stefan

We are wanting to use the Hole Report Table on our drawings for holes in tubes we create in piping. However one issue we are having is that if there are more than one hole the hole location or "offset" as is shown in the table is not based off the start of the tube but off the prevous hole. This would require the person drilling the hole to add, and we cant ask them to do math. Is it possible to have the offset and angle all come off the one end point? Also we have problems if the tube is started at different end and then "connected" together the dims we get in the table are strange. That issue is hard to describe.

Good Afternoon Community,   Attached is a copy of Mathcad 15 file that I'm working on. I'm trying to convert a Matlab code into Mathcad file, I have done some work on the worksheet, but I ran into problem in converting Matlab programming into Mathcad programming. The Matlab code is at end of the worksheet. Would anybody please help me with the worksheet, my goal is to plot the time history of displacement, velocity and acceleration. Thank you in advance.   Boyer

I try, try, try use this again, again, again

Why i can't start PTC Mathcad in Creo 4.0 M020 in Application Tab? Here are my operations: I install Creo 4.0 M010; I install PTC Mathcad Prime 4.0, it is success to start PTC Mathcad in Creo 4.0 M010 in Application Tab; Then i uninstall all compoents of Creo 4.0 M010, and install Creo 4.0 M020; it is fail to start PTC Mathcad in Creo 4.0 M010 in Application Tab, just like the picture below; How to repair itso that i can start PTC Mathcad in Creo 4.0 M020 in Application Tab?

It is not an idea - it is one question! What do you think about it?   See more About Mathcad PM

Hi, I need a function that can characteris 3 sets of data. Ideally a function like this z=f(x,y). So X and Y are inputs resulting in Z.    The 3 sets of data consist of forward current, voltage and temperature measurments of a diode.

Please see attached Prime 4  file that I am stuck with.   I am trying to solve for two unknows and plot one of them.  Plot n.   I have had  success with one varible which I have attached as pictures in the mathcad.   Thanks  for all the  assistance that I know will be forthcoming.   Regards

Below is an example of an equation and its respective plot.  Everything seems correct and as expected.     Then I define a range... and the plot stops being valid below 1.     Does anyone have any ideas as to what may be causing such behaviour?

  Hello there, I have a problem to get multiple answers from this equation, It can be solved if put the value one by one,  kindly refer attached file for the problem. thanks in advanced    

  I have Prime 4 up and running.  To convert legacy files, I installed Mathcad 15 like is says it needs.  Both work fine. However, the converter feature just doesn't work.  Every legacy file I try to convert says converstion failed, process aborted.  No other info.  I have not gotten any legacy file to convert.  So far conversion to Prime has been a bust.  These are simple files, maybe a jpg image or two.  Very Frustrating.   Curt Fortenberry

I'm wondering if other users can confirm this issue.  Upon switching to 4.0 it has become difficult to get MC to define a custom unit.  I occasionally had problems in 3.0/3.1 - but nothing like this.  It only works about 10% of the time.  I can paste custom units from another file and they work, but can't define new ones with the label styles menu.  Also having similar issues with defining constants or functions.   Thanks,

Greetings all   I would like to simplify the expression in the attached worksheet (and image), however I am faced with the "out of memory" error, which occurs after about 30minutes of processing. I have 16GB ram, i7-4790 CPU at 3.6Ghz, 64 bit Windows 10, MathCAD version 15. Please note that all letters are variables, and I intend for none of them to hold any particular value. To avoid confusing MathCAD I have tried replacing e,i, and j by different letters, but to no avail.   I predict that the result will be in numerator/denominator form, with numerator having a sum of  x^2*y^2, x^2, y^2, xy, and the denomiator having neither x nor y.   Please would someone comment on the use of "simplify,max" and if it has any relevance to me.   Thank you kindly.

I tried converting a 7yr old MathCAD 11 spreadsheet to MathCAD 14 (then to 15) to solve a transient Heat Conduction Equation in Cylindrical Geometry. I used the old spreadsheet (attached) to evaluate at heatup of electrical cables from an external fire source about 6-7 years ago. The standard tools (Pdesolve, CreteMesh,..) don't seem to work in later versions of MathCAD.The current problem to be simulated is localized heat-up of a Tin foil via passing electrical current through a localized area with effective Radius Ro.The problem involves just one function: Ttin(r,t) - temperature as a function of radius and time, one initial condition, boundary conditions near the origin and farther away, and a time varying heat input source concentrated within Ro.The Pdesolve (....) block does not appear to generate an error message. I've tried all four of the curve-fitting solver options and cannot generate the mesh needed to generate solution plots. The Error Message is: "The number of functions m

I'm not sure what I'm doing wrong but Mathcad is taking far longer than I would expect to create simple arrays.   Goal: create an array with 86,400 rows, all values are 0   For example, I can make an array like that immediately with B[86400 := 0.   However if i try to do the same thing using a while or for loop it takes nearly a minute.    C:] t<--86400    ] j<--0    ] while j<t+1    ]  ] C[j <--0    ]  ] j<--j+1    ] C   Now the program I'm actually trying to write is a little more complicated but I need to write arrays/matrices using programs.  My current file takes 20 min to run which is far to much considering that the calculations are not intense.  I figure I must be making mathcad work harder than necessary.  What am I doing wrong?
