Hello everyoneI have a problema with Sz1 (i need to use 0 < r < a) and Sz2 (i need to use a <= r < infinite)I need to graph both Sz1 and Sz2 in the same plotI upload the file poynting.mcdxthank you for your help
hello everyoneI have problems with graph Sz2 in the same plot where is Sz1help me pleasethank you
I'm stacking different plates and need to know a property (modulus) at any given height depending on which plate that height falls into. I toyed with lookups, matches and ifs but the only thing I got to work is shown here. It does work, but it doesn't seem very efficient for what I thought was a simple problem. I'm betting there is a very elegant solution. I'd appreciate any improvements. Thanks. (Prime 3.1)

Hello.I'm having trouble combining 2 "IF" statements. I'm sure this is a piece of cake for you experts.Here is the general form of my program (the actual equations are more complicated).X=A If M=1X=B If M=2 and If N=1X=C If M=2 and If N=0 (or simply X=C otherwise)Thanks, Al Clark
I am looking for a spreadsheet / template for calculating bolted connections based on the Eurocode (EC3) design code. Does anybody know if there is a free/buy MathCad sheet for this?Thanks in advance.
Hi All,I want to use a parametrized solve block in a programing loop. The problem is that the solve block gives two output with two units, pressure and tempreature; so I cannot assign it to a function.I appreciate any hints.Thanks in advance.
I wanna join or pass many matrices in only one....Please look the attached imageits posible?
Saludos,Descargué la versión de prueba del MathCAd 3.1 y al abrir el programa aparece el siguiente error y se cierra el programa. Su valiosa ayuda para resolver ese error ya que no se puede trabajar con el programa. Gracias
Getting the following error message during the installation:An error occurred during the installation of assembly 'Microsoft.VC90.ATL,type="win32",version="9.0.30729.4148",publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="amd64"'. Please refer to Help and Support for more information.Any hints?Thanks
I have various data sets I'm performing some analysis on. Sometimes they have blanks, sometimes not. I can easily filter out the blanks with filterNaN. The problem is if there are no blanks the filterNaN errors out. So, I have to rewrite the statements for each column as to whether I need to filter or not. I'd like one command that works whether I have blanks or not. What are my options? Here's a simple example: Here, I want to return B = [1 2 3 4 5]^TPrime 3.1 (and is this a bug?)Thanks,
Hi All, I have a function which including two exponential components, whose power factor x and y are different. I was trying to solve it by hand or by Mathcad solver, but did not succeed. Would anyone give me the instruction how to do this?Since an approximated solution is also acceptable, I also tried to use the brute force method, in using match(0.9, XXX) and match(0.1, XXX) to solve, but it seems an exact match cannot be achieved. If someone can teach me how to get the approximated match, that would also be very helpful. Thank you!
HelloOnce again a silly interface question: I have a vector in polar form. Now I could easily write down the real and the imaginary values down go on from there but I want to be able to define the angle of the vector so that I can use that angle later on. However I can not find a MathCad feature or some neat trick to get that angle defined. I have attached a picture with an example to show you what I mean.I hope one of you have a neat solution. I use MathCad 3.1 by the way.Best regardsEmil
I have the attached linear system. I want to solve for X1, X2, and X3 symbolically. three equations three unknowns, however the coefficients are unknown. Is this possible in MathCAD?
Hi everyone!It seems strange to me, but I am not finding in the forum any previous post to the subject. I need to calculate the Complete Elliptic Integral of the 2nd kind.Since it will be evaluated many times inside a double loop, it would be probably unwise to define it using its "integral definition", because of performance.(from Wikipedia... sorry, I am not a mathematician...)Has someone good advice for me? What I am going to try is to use the "Gauss hypergeometric function" that seems to be available in Mathcad (fhyper)Nevertheless I am unsure if this is a good idea.Thanks a lot for any hintsBest regardsClaudio
I'm trying to solve a mechanical problem in Mathcad, but some of the initial values are not getting accepted. Can you please help me finding the problem?
Can MathCad fit spectral curve with functions containing complex values? Do we need any package?
How does one break up long equations in Mathcad Prime 3.1 so as to keep the equation all on one sheet? I think I used <ctrl><enter> before but it seems like they got rid of it. Thank you very much!
Mathlab has a way to read signal from analog instruments with 4-20 mA outputsMAthcad has the same ability??obiusly it need a card to transform the signal in real number I need to read this real number into a vectorn
I have not any solution in Mathcad 15. The problem about catenary with potential energy.I have convert the sheet in Prime 3.1 - now I have solution!New solver is more powerful! Or?And second - how is i:=1..n in solve block?
Hi everyone, This is David Maloy,It has been a long time sense I have posted a "Help request".Ihave a problem with a formula and MathCAD Prime 3.1.My goals. I need to rearrange the formula so that the equation is set to solve for the "h" value.Thanks in Advance...Dave Maloy
Sorry, I am not a Mathematician.What is it the second root? See please the picture and Mathcad 15 sheet in attach.Same in Maple
See please the Mathcad Prime 3 sheet in attach.One transport problem - see Prime (with me) cannot solve a transportation problem
