If you have nested range variables, which loop gets executed fastest? For example in the following the trace indicates the inner loop gets executed fastest, but if you swap the a and b lines, the outer loop loop now seems to be executed fastest???  

Hello,   I need the solution for the problem shown in the attached photo asap. Thanks in advance.

If it isn't obvious from my subject, I'm using Prime 5.  I've run into a few issues where a partial derivative will incorrectly evaluate both symbolically and numerically as 0.  I've attached two files, both are pretty stripped down just to illustrate what I'm seeing.    The first, derivative_error.mcdx, illustrates the issue with a fairly simple example. You can see that the derivatives with respect to the first two variables are correct but the last three evaluate to 0.   In the second file, derivative_error2.mcdx, all I did was rename essentially everything and the issue magically disappeared.  This has been my only method around this issue to-date.  Move a piece of my work to a different file, play with variable names, eventually things start working.  I've never been able to fix the issue in my original file though.     I've searched this forum quite a bit and haven't seen a similar issue.  I'm either doing something real

Hi,   I'm new to mathcad and I'm sure this is an easy thing to do but I can't for the life of me figure it out from documentation and existing threads.   All I'm trying to do is simplify the results of a symbolic evaluation. Right now, MathCAD is returning this:   It's pretty obvious that the RHS is equal to 5.758*F0/in^2. There must be a way to get MathCAD to return this simplified form of the expression, right? Can somebody please show me how to do that?   Similarly, I have another expression in which MathCAD expresses units as in^2*psi.   It would sure be nice to display those units as lbf. Does anybody know how to do that?   Thank you!

Greeting, I wanted to plot a function which is the addition of a sine wave and logarithm base e but I couldn't get it to work. Can somebody help me? I am new to Mathcad, please bear with me.

Hello all   I'm trying to get the indices of values in a vector that are less than or equal to a threshold value. From the documentation, it seems that I should use match(threshold, vector, "leq") but this gives the error "This function accepts at most 2 arguments but is applied to 3". The relevant code snippet is below.   I've looked at the docs and forums but can't find any code examples using the third argument as specified in the docs. I've tried "leq" with and without the quotes.   I would really appreciate any help! What am I doing wrong?  

Hello. I am trying to extract values from a matrix according to certain restrictions, with no success! In the file attached is the attempt. Any help would be greatly appreciated. 

See please here Mice problem about this task! You can see in attach a Mathcad 15 file with solution of this problem. But I think that will be better to use not a X-Y system but a Polar system of coordinate - for the calculation and for the plotting - not only for 4 animals but for 3, 5, 6 etc. Help me please!  

  How do a allocate a variable to another variable based on conditional check? Attached a picture and Mathcad Prime 4 file. Thanks.

Is it possible to set the default behavior when double-clicking an MCTX (Mathcad template) so that a new file is created, instead of opening the template itself? You can do this with Word, Excel, etc. Wondering if it's possible to do for Mathcad as well.

Hello,   I have a working simulation worksheet that runs a Monte Carlo analysis on a function.  With the results, I can bin the simulations for the input variables as well as for the output.  I am struggling though, to find references on how I might "tease" out the relative contribution of sources of variance.     Are there any suggestions for using the input function, along with known means and standard deviations of the input variables to establish these values?     Is there an analytical way to look at the result of the Monte Carlo simulations and determine relative variance?   Sorry for the abstraction in advance...I attached my Monte Carlo simulation up to this point, but couldn't even begin to try and "mock up" what I am asking for help with.

Hi everyone,Qucik question for all you MathCAD geniuses (or is that genii?) out there.Is there any way to redirect where MathCAD 15 looks for its templates?As in most offices, we're on a network. There are several engineers in the office and to keep a tight control on documents, we all use the same template whenever we start a calculation. But it's very tedious having to open up the template document from the server everytime we want to create a new document (especially as we use Meridian which seems to make you wait for no particular reason sometimes) It would be much easier using the "new" drop down menu and going straight to it.I've tried creating a shortcut to the template document then droping the shortcut in the template folder on my C drive (C:\Program Files (x86)\Mathcad\Mathcad 15\template\EN) but to no avail as MathCAD doesn't seem to recognise shortcuts when starting a new document.I'm just looking for a way to either make MathCAD look at a different folder to the deault tem

Hello,    I want to solve an equation with vectors symbolically. The equation itself can be solved symbolically by Mathcad. The symbolically result of the equation can not be shown, but it can be used if I assign the equation to a function.  Now I want to use vectors with many data to get a solution for my unknown variable xB. I tried to use a Control variable i, but that did not work. If the values are inserted into the equation directly, Mathcad finds two Solutions. So my Question is if someone finds a way to get a solution for xB and even if it is possible to solve an equation with vectors symbolically?  The file is attached below.   Thank you for your help!    Christina

Good morning everyone,   I was trying to print my results and I noticed that the lines are shifted in the PDF (see image attached).   I tried several printers but always the same result.   Anyone knows how to fix this?   Thank you for helping,   F.

Greetings, I just started learning Mathcad and have been getting incorrect calculations using the sin function, when t=1s and 2s, Mathcad gives me the same result and the result is not even correct (t=1s, it should've been 3.41 not 4.33; when t=2s, it should've been 2.193), I am also getting a straight curve instead of a sin wave. Can anybody help me out?       

  can someone please help. i have tried everything but i can not get it to calculate. Keeps saying Units are not compatible    

I am trying to solve a simple PDE (Fourier equation). Initial condition is 0, BC - at x=1, Temp=1 and x=0 the flux is zero due to symmetry.   I am getting zeros for solution. What am I doing wrong?  Thanks.

Hi, I am trying to solve  a simple differential equation that uses an excel acceleration vs time as the driving force. I have used linterp to ensure that time values used in the solve can be extracted from the input acceleration versus time data.There also seems to be an issue with too many initial conditions. I would have thought you need 4 but this solve block only seems to need 3? Any assistance would be appreciated. Thanks ross

Hello, I am new to MathCad (version 15.0). I found similar issue in other posts but I was not able to implement it. I want to solve a system of equation for 4 equations and 4 variables. I receive the error "The symbolic result is too large to display". I need the symbolic result, because I am trying to find a general formula for any number of equations and variables for a specific problem .I'd appreciate it if you could help me with this issue.   I have attached the relevant file.   Thanks. Abed.

Hi, Mathcad close automatically but an automatic save has been created. Othewise, the file cannot be open, see the warning message and the file in attachment. The extension is good and the file is not empty (8646 ko). Thank you for your help. Bianca

I am trying to solve an equation using find but it seems not working. it says that "this variable is undefined". Really appreciate your help. The file is attached.

Dear helpers,   I am currently trying to solve the reaction of a laminated plate by using the Newmark-Integration-Scheme based on the First Order Shear Deformation Theory (the force acting on the plate is sinusoidal in time). Therefor I wrote a loop which calculates the needed Wmn for every next time step dependent on values of the current timestep.   My problem is that this calculation needs a lot of time at the moment (especially when I try to plot the last equation) so I can't see if my calculations are correct.    My question is if there is any mistake I did by programming the loop because this is the first time I was programming in mathcad.    I am thankful for every advice. Thanks, Felix    

Hello All,   want to know if Mathcad prime API can be used for developing wen applications too.   thanks, Shah
