Hi, before i build some .dll files and work well in mathcad 15. I install mathcad prime 7 and try to reuse these .dll files, but cannot load dll function. These dll files are put in the folder "C:\Program Files\PTC\Mathcad Prime 7.0.0.0\Custom Functions". Or should i put them to another folder or something i should do previously?

Hello Everyone.   Ive not got much experience in Mathcad so hoping you can help me with a simple program I have been trying to write.  Basically I have set up a table, with two columns "a" and "b" and what I was looking to do was write a program that evaluates an if/else statement for each row.  If a is greater than 2 then carry out a+b if a is not greater than 2 then carry out a-b.    At the moment I can get it to work for the first part however when I add in the else statement it looks to me like a single row complying with the else statement means that this is applied to every single row rather than just the individual row.    Is it possible to have this program evaluating each row independently of each other?    I've attached my file and a screenshot of the sheet as well.     If you guys need more information please let me know.  Also I am no expert so if there are better ways of doing this, anything I have done that

Hello,I want to find out the intersection between these 2 graphs, how can I find it? Thanks.

Hi,I am running Mathcad 15 student edition on a Windows XP PC. I will be selling this PC in Canada, moving to England, buying a new PC which will run Windows 7 and installing Mathcad on the new PC. What are the steps I need to take to transfer the Mathcad license?Thanks

Hi there,   the PTC Mathcad help say if i want to use a matrix as Input Data for 3D Plots there are 2 ways:   • A 3-column matrix, where the three columns represent the x-, y-, and z-coordinates • A m*n matrix, where the cell’s indices represent the x- and y-coordinates and the cell values represent the z coordinates   I need the first one, but my Mathcad (using Mathcad 15) allways plots my matrix like the second case.   How can I change this and tell the Plot that my matrix has the coordinates in the collums and not int the indices and values?   thanks a lot ❤️

I need parameterized solution from two equations. Both equations have two variables in them. . I am using "find". I tried "solve" (not shown in attached file) as well but could not succeed. How to get it? I tried everything since past 3 days. Searched extensively in Mathcad community. Pls help me in getting it. Pardon, if this is too simple to answer, but answer pls......Thank you very much.

When i right click -> Insert -> Table, NOTHING happens. Nothing at all. Also nothing when i use the Insert -> Data -> table. This happens whether i open a blank document or in the middle of a document.I'm running Mathcad 15.0 (M010 [MC15_M010_20110622]) on Windows 8.1 with my schools license. I have tried compatibility mode for Windows 7, XPSP2 and XPSP3 and i have tried administration rights. My classmates can it to work though. (they run same MathCad but differnet Windows (not 8.1)). I have tried reinstalling mathcad several times. Nothing changes.I should mention that under the installation there is around 15 error messages that i can not get around (have to click ignore) because i have windows 8 and Mathcad does not support newer OS.How can i fix this without installing different Windows?

Hello,Shouldn't the graphs look the same? Thanks.

Is it possible to add information from the excel sheet in combo box? Also, is it possible to address a certain row within combo box from matrix or a specified table in the worksheet

Hello Everyone,The data for cornea topography is loaded in the worksheet attached. The contour plot is generated using the 2-D interpolation algorithm. However, when compared to the topography system's original performance, the plot has a very low resolution. How can I get a plot that looks like the system output?  I was also curious about how the data could be transferred and plotted in polar coordinates because I was having trouble mapping f(x,y) to f(r, theta) coordinates.   Any advice will be greatly appreciated. All the best, Payman.

I just started to use Mathcad... I was try to find the sqrt of a value in N/mm^2 and my end result was given in units (Kg^1/2) /(m^1/2)s... I do not understand why it is happening... Can anyone help me out... 

Hello,Is it possible to do somehow the simplifications described below in Mathcad 11?     (The expression of Gc(s) is not quite visible in the image because it is a rather long-expression.Look in the Mathcad 11 file to get a better look at Gc(s)'s expression.)Can the expression of Gc(s) be further somehow simplified? that is, instead of pi to be 3,141 (or how close Mathcad is to pi or how Mathcad approximate the value of pi), and possibly other calculations to be reduced (to do the multiplication, division operations) so that the expression, if possible, is simplified. (Mathcad 11 File) Thanks.

In the attached plot i have power dissipation on y -axis and  time  on x-axis. My objective to integrate the waveform(on y axis- Area under curve) and then divide by time(x-axis: Time taken for covered area ) to get the average power dissipation. I am trying get an integral plot similar to the one  we get in the math waveform (integral function) in oscilloscope. I am attaching a video link regarding the same https://youtu.be/Dh0xYu8YvaE     I am also enclosing the .csv file

Hello,It is possible to somehow find the inverse of a() (a()^-1) and E*((s*I6-a())^-1)*b()+f symbolically?   (Mathcad 15 file)Thanks.

Hello,What is the syntax to determine the Jacobian of a matrix in Mathcad 11? (Mathcad 11 File) Thanks.

Hello,It is possible to find the numerical solution to this system of equations?   (Mathcad 15 File)Thanks.

Hi there, fellow users in MathCad. I'm totally a beginner in MathCad. I don't know why Mathcad said the variable is undefined when I try to solve the integral function.  When I put my task's value which are a=-2 and b=4 the integral function said it's value is undefined. Where did I do wrong? Is there any other command that I should add ?Regards,Adlil

Hi, I need help to figure out how to plot  different values of Rac (Disabled region in attached file) against Frequency(F)   Thank you Jacob

There appears to be an issue with the combo box with regard to exponents. 1. When inside the box the Exponentiation (Xn) is greyed out and I have to type it by hand (^) when entering values. This however puts the box on red alert and it either refuses to work or crashes. 2. It also looks weird as if something's wrong. Does anybody know what I'm doing wrong? Attached is a Prime 7 file.

Good day to all forum visitors! Tried to apply IF statement inside the cycle to change condition variable WHITE, but encountered error - Unitless (Mathcad 15). Rummaged through forum and mathcad literature, could not find anything( Who can give advice?   Thank you in advance!

Hello,   I would like to solve the differential equation in the document. However, Mathcad can only calculate the values if I use a positive factor. In Python the values are calculated without any problems. What am I doing wrong? The problem exists in Mathcad 15, as well as in Prime 6.0. Thank you very much for any hints. Best regards Paul

Hello all,   I have datapoints, expressed in a x-vector and a y-vector.   Just by plotting x and y the points are already pretty smooth. The gradient between the first x-points is very big, so I would like to smooth the curve even more. How do I do it the best way? Interpolation between points is the answer, but how to I do it in mathcad?    I attached a mathcad prime 3.0 sheet where I try to do some tests, but without success so far.     The graph in the screenshot is already pretty accurate, but thats because I have enough datapoints.   In a worst case, where I cannot obtain enough datapoints, I would need some kind of interpolation...       The optimum would be even to reconstruct a function out datapoints. Is this possible? I could do further analysis by having a function f(x)   The datapoints were obtained from this graph for thermal resistance over a copper area:       Best regards!

"The race course was a large three-mile ring of the form of an ellipse...". Anna Karenina, by Leo Tolstoy Translated by Constance Garnett In Russian text not three-mile, but 4 versta (верста). Versta = 500 Sagen (сажень), Sagen = 7 feets. The problem. The workers marked this racetrack like that. They took a rope and tied it with both ends to two pegs driven into the ground and spaced one versta (see above) from each other. Then they pulled this rope and drew an ellipse. How long was this rope? What is the canonic formula of this ellipse?Who will give the best solution? 

Have any of you guys got a good solution for being able to distinguish psig and psia in a worksheet? I would like to be able to define the local atmosphere in the sheet and then work with either the gauge or absolute pressures in the sheet. Seems like this should be simple but an elegant solution is eluding me.  Thanks!

There is no placeholder for units in chart component The old plot had unit place holder for scaling the graph units This seems to be missing in MP 7   Also using the chart component in the input area they are not automatically Assigned units to x and y expression I cannot see Corresponding base units displayed which makes it even more difficult  What is the solution for this??
