As I am trying to solve one problem for my project, I am facing difficulties to solve the loop.I am looking for Buckling Pressure for different L.b and K value.Can you please help me out.

I am trying o save my data as a text or cvs file. However, I keeping getting an error "this values must be real." I know al te values are real. They have been plotted. The program is pretty simple. There is a range of variables that are used for several functions then the final output would b the Ne1(range) function. I have attached a copy of the program. Hopefully, someone has an idea on what I need to do to save this data.

Hello Everyone.From :The question is : Need help creating a Program Function for "Zeckendorf Representation for Natural Number (2017) with Lucas Numbers ?      Thanks in advance for your time and help.            Best Regards.

As you can see in the attached file, i have 2 matrices and i want to check a condition for each element  and to show the result depending on the condition that is fulfilled. When i try the normal "if" condition it says that it has to be a scalar.. i know I have to access at each element but i dont know how.Thanks in advance

Hi,when i want to write X^2 typing on italian keyboard ( X ) ( shift+ì ) ( 2 ), worksheet appears as below:   is there a patch to solve this problem?I've just tried another key combinations (for example setting english keybord) but with the same result.Could you help me?Thanks.Let me know.

Hello Everyone.   The question is : Solve, 5 of Fibonacci numbers  =  5 of Lucas numbers ?               Thanks in advance for your time and help.              Regards.

Mathcad Prime – это новый корабль, который построили для замены старого – Mathcad 15. Оба корабля находятся в плавании, но старый корабль скоро пойдет на слом. Поэтому с него на ходу перегружают в новый корабль все ценное. Mathcad Prime - a new ship, which was built to replace the old - Mathcad 15. Both ships are at sea, but the old ship will soon be scrapped. Therefore, it is transferred to the move to the new ship all valuable.

Could some kind and gentile soul explain to me (one more time) the ins and outs of units, altering default units in a particular worksheet and/or setting preferred units in Mathcad prime 3.0My calculations don't come out right or they don't look right (WYSIWYG) for the human eye. I have problems with the definition of inertia. I attached some offending parts from my main calculation file.Thanks maurits

Good day. I was wondering why the XMCD, MCD Converter option is grayed out in my Mathcad software? (Please see attached image). Any help would be appreciated!

This problem has been persistent for a while. A text document appears after I click print.

Why are all plots consistent except plot 6? please see worksheet.

HiI have succesfully upgraded to Prime 3.1 from 3.0.Does anyone know how to install Prime 3.0 to run with 3.1 simultanuesly?Or how to downgrade 3.1 to 3.0?Or how to uninstall 3.1 to then install 3.0?Thanks in advanceMichael

Hi,I was looking for a way of easily searching a data matrix "lookup table" with an array vector to extract a value for use in later calculations. I've seen a post where a single value is used to extract a row of data (I need to extract one row of a matrix) and was wondering if this can be somehow extended to be an vector array to extract a single value "alpha". A nominal array and the proposed data matrix would be similar to that below. I've attached a worksheet if that assists?Also saw this Build New Matrix by Selecting Specific Columns of Another Matrix maybe this has potential to offer an alternate way of extracting the row then alpha value using this as an approach, cant quiet get my head around the matrix math to see a way through... Thanks in advance  Message was edited by: Peter Darby

Guys, I'm trying to make a linkage between Ansys Workbench and Creo Parametric 3.0. But this error keep on popping out. What should I do? URGENT!!

Hi all I want to scoot over same function a few units to the right. I am trying this but at the end is not moving to the right the 8 ft axtra that started. also graph 2 does not seem right. please advise.

Greetings.I need a calculation to find center of gravity of an object.The closest I could get is to define functions, like a bottom and top mould, so I can integrate between.I would need some help now in how to define these functions in a more practical/elegant way, something that could be typed in quick, say like coordinates, also easy to check and verify. A method that is easy to apply for any object with polygon faces.Any advice?

I am trying to figure out how to plot a centrifugal pump performance curve in mathcad prime 3.1. I have defined all the variables and reduced the pump head equation so that it is dependent only on the volume flowrate. It is gas flowing through the system and i want to see the performance curve for volume flowrates between 0 and 500 gpm. When i try to plot the function it does not do it and instead i get an error on the plot box saying "Plotting failed. Replace complex values and NaNs by real numbers." None of the values i am dealing with is complex and there are no square roots to make it complex. Whats even stranger is i have defined the head pump as function of flowrate and when plugging in values for the flowrate i get correct answers (e.g. h(300 gpm)=1169 ft.). So why is it not plotting the function though? I attached my mathcad file so you can see what i am talking about.

In mathcad 15:The answer is as expected. In Prime there are rounding issues. How do I eliminate this rounding?

I am trying to do some simple math to integrate a step change function using Mathcad 15.The problem as simple as a capacitor has two values, at a threshold voltage.When the voltage is below one value, say 20V, the capacitor is large, say 40pFWhen the voltage is above the threshold, 20V, the capacitor is small, say 20pF.To calculate the charge in the cap as a function of capacitor voltage, I can do it two ways.1, Define the capacitor value as a function of voltage and describe it as if function. Then integrate the capacitor with voltage to get charge.2. directly integrated capacitor with voltage and put the if function in the integration equation.The two results are very similar, however, the method one has significant error comparing with second method. See the attachment.Is there any thing wrong with the algorithms inside the Mathcad that having trouble to handling the if function inside integration? I am using the integration with if function a lot and really concerning on the accura

Hello,i have question about repeating calculating of sheet. I would like to type a program where is important change input according on the result. Example.a=1,1X:=some equationX=6and it is less than I need, so I need to change the a argument. I need to by it automatically. Thank you for answer. Tomáš Martinka

Hello Everyone,I hope my email finds everyone in good health. Can anyone please help me how to actually find the interpolation function when I use the command "interp". I have attached a file that interpolates frequency based on phase angles and I have plotted the graph. But I would like to what is the equation that I have used here using "interp" and "cspline".Thank you,Faisal

Hello.Where can i see when my mathcad student license expires? Because i have installed the program on 2 different computers, with the same key. But they dont have the same expiration date??Hope you can help....Andreas
