Mathcad

I am using the insert excel component to input data. The data consist of columns with sparatic values in columns C-I. Columns A&B are completely full. I want to graph the sparitic values in C-I against col A. When the data is imported, all of the blank cell come in as zero. when plotting they also plot as zero. I want the plot to connect each value ignoring the zero's that were brought in.Any ideas?thanksRon

I get an error with Radau(init, x1, x2, intvls, D) as 'This value must be a vector.' I'm quite sure I made init and D vectors, and x1 x2 intvls ordinary numbers. Please see the attachment and tell me where the problem is. thanks

HiI hope someone here can help me!I am trying to visualize a function with 2 independent variables like z(x,y) := .... but it does not work.Everytime I generate a "Surface Diagram" / "Surface Plot" and say which function I want to get visualized, Mathcad says "The variable is not defined." to one of the two independents.I look forward for some useful hints!

Hi, Fourier transformation is usually based on exp(jwt). How Can I address Mathcad to do Fourier transformation based on exp(2jwt)

I need to find the coefficients for the functions f_3(x) and g_3(x) that describe the median curves (curve equidistantly spaced from the curve f_1(x)/f_2(x) and g_1(x)/g_2(x), respectively).

I am running a Latin Hyprecube Sampling routine for statistical reliability analysis. I randomdly sample from 9 probability distributions of parameters that from inputs to a crack growth integral equation. When I take a larger number of samples you get unlucky and at least one of combinations of parameter inputs to the integral results in the integral failing to converge for that combination and this results in an error. Is there a way of including a diagnostic line in the program loop that will flag that a combination does not converge (eg like a "time-out" in convergence iterations) but then record this combination as not converging and then continue on with the loop?The attached sheet usually works for several hundred samples but when say n > 300 it often flags an error (sometimes you may need a large number of samples before you get unlucky eg. n = 10,000) which I have been able to isolate through trial and error to prove there is a particular combination that does not converge.

I have MathCAD 15 (M030 [MC15_M030_20131216]) running on a 64 bit Windows 7 laptop with 8gb of RAM and an Intel Core i3 processor. When I run programs that reach a certain length, the whole block turns into a blue mesh. It still works, and the subsequent calculations are good, but I am unable to edit the block. It was discovered earlier today that I could get rid of it by pressing pg up or pg dn (not by scrolling), but it returns again. I've been able to perfectly run the code on every other computer I've tried it on. I've included a screen shot of how it looks and have attached the worksheet. Thanks in advance for any help.

Hello, everyone.I want to solve a somehow complicated ODE system of 5 equations. But the Software seems have problem to solve it.If I change the y5 in the 4th line of my DD matrix, it can be solved. But the results are definitely what I expected.Please check the attachment for the situation.So the questions are:1. Why the MathCAD have problem with solving my origenal matrix?2. what change I need to make to get the results?

Hello,I really don't know how to name this, but here is what I'm trying to do:Let's say cos(2*mt+phi)= -sin(b)/sin(phi); Is there a function in Mathcad Prime 3 that can extract "mt" from the equation and deliver it like : mt = 2 arccos (2*phi)/-sin(b)*sin(phi)? (this is just an example)

HiI'm having trouble installing mathcad 15 on my windows 8 laptop. Does anyone know how to do it?

My installation of MathCAD 14 is messed up. It used to work correctly, but now the multiplication symbol has turned into an empty square. I can't figure out how to restore it to normal. I tried uninstalling and reinstalling MathCAD but it didn't change the behavior.Also, a left-paren and right parent look normal when on just one line. But if I put parens around a fraction e.g. (3/4) I see a a bunch of empty boxes instead of the parentheses.

Hello dear members do not help with the solution? I will be very grateful.

Though one of the 3 variables (of same units) is already defined & worked out but still in the final expression (using these 3 variables) for this particular variable it shows the following warning msg that "This value has units: Force, but must have units: Unitless" & not provoding the result in kN.Kindly suggest to resolve.RegardsPrateek Agarwal.

Hello,I've got a surface plot of some X, Y, Z data that is correct. However, when I add contour lines (or do the 2D contour plot), there are extra contours that do not exist in my data. My Z axis should only have data from 200 to 1100, but in the picture, you can see data well below 200 into the negative values, and some data that exists above 1100. It appears mathcad is trying to interpolate data that isn't there to fill whitespace. When I fill the backplane, it only tints the contours that don't exist with the shade of the backplane fill.Any fixes, or is this a glitch in 15?Thanks

Hello,I'm looking for docoumentation to use a VBA program to call up mathcad and have it calculate a spline for a data set, then send the data back to excel. I can locate my array I need to send in my data just fine, but I'm unsure how to call up MathCad.As an example, here is the mathcad worksheet I'd like to send the data to with VBA. Please not that the data size changes in length depending on the collection run.

Hello,Looking to get multiple outputs from a solve block where some of the outputs are intermediate stages in the calculations. I'm getting an error when I try the normal things one might think of such as entering Tso(Tfo) and Tsi(Tfo). Looking to use the solve block becuase it is faster, but I can stick with the programmed version if that is necessary.I like the Solve block version more, becuase the accuracy should be greater regarding the equations due to where I inserted the radiation componenet, though I think they should be fairly close for the majority of items.

Hi All, I was exploring the objects link at db level. Is there any procedure or way/Utility get entity relationship links at db level.Need guidance to understand.Kindly share your Ideas. Example: How "WTPART", WTDOCUMENT" "WTPartDescribeLink" tables are related in DB, which columns of part & document table has been mapped to WTPartDescribeLink table. Thanks,Chanhasen

Hi, I have one question I hope you guys can help me with. I am struggling to get the designations (unit) correct. When I decompose forces I get F (Farad) instead of kg. Please see attached photo to illustrate the problem. I use MathCAD 15 and Windows 8 (if this is relevant). I hope someone can help me, and, in advance, thank you. Best RegardsKjartan

Hello everyoneI did a worksheet in Mathcad and i am looking for a wayy to export the worksheet to a html format like, i think i saw before some worksheets that can be opened in explorer, mozilla, etc. im not totally sure though, what i want to do i use it for a presentation in a classroom in a computer that doesnt have Mathcad.Thanks in advanceAlex

I want to be able to read a known number of multiple input values from one excel sheet and populate the corresponding multiple outputs in another worksheet Those outputs will be a mix of values and text. To do this I assume I need a programming loop. I have a complex worksheet but can someone show me how to do with this in principal with this simple example ?G

Hi!You guys have been such a help for me, and tommerow is my final exam. Yay!Though, I still have one problem.. I really can't figure out how to make a repeating periodic function.An example would be the uploaded file, where I'm trying to make a function look like this.Though I can make the function from -2 -> 2, I cannot figure out how to make it repeatable, like the picture.I really do appericiate any help I can get!Best regardsBen

Please see attached. I can display each ANS(h) for all the vairables answered in the simultaneous equation as shown. However, would like to graph each of the vairables (for example F1Dx) versus (h). Thanks!Steve T.

Good Morning MathCAD Group,Would anybody be kind to help me with the attached files. In the first file, I have pasted the table I'm trying to interpolate and MathCAD interpolation code that I have written, that I think is not working. I have in the table three different values that need to be interpolated before arriving at the correct answer.My second file is trying to program the stiffness of a pile group with a battered pile at different angles.Would anybody please help. Thank you.Regards,Boyer

The MathCAD community may find the attached article interesting. In a largely academic setting we sometime lose sight of the fact that mathematical errors have real world consequences. The Wanapum Dam is rated at 1040 megawatts, construction started in 1959 and operations stared in 1963.

I have this complicated function S(x,y,z) which also reads from previously defined functions. The plot capabilities of mathcas is nowhere near publication quality. I wanted to somehow transfer this plot to another software that has acceptable plotting abilities (e.g. Excel) but I can't find any way to do that. can someone please help me?
