Hi,How to myltiply single column to column in matched prime like excel

Is there a person who kindly would like to dedicate some time to my little problem? I would like to know if the difference  method  and the amplification matrix are accurate.Thanks so much.F. M.

Hey guys, im there with another very special question because of my limited Mathcad Knowledge.Now as following my last Posting i extended my Mathcad Loop and i think my Calculation is resulting in the results which i need to know.Now as an short explanation:The Input File for the Calculation is the Excel File.Table 2 from D2-D33 are the input Parameters for the Calculation.The Result of the Calculation is written in The same Excel File in row 51 and 53.In Mathcad are 2 Calculations implementet.1) Calculation of maximum axialforce with a given moment (marked as yellow in the sheet)2) Calculation of maximum moment with a given axialforce (marked as orange in the sheet)Now the first Calculation as seen in D1 is for calculating maximum force and momentum.------------------------------------------------Now what i need to know:The next step is to perform a Variation Calculation with the scalingfactor as seen in C36 (applied to maximum force row 38 and 39).------------------------------------

Hi all,I've been using Mathcad Prime 2.0 and 3.0 for sometime and upgraded to 3.1 recently. Has anyone found that it seems to crash often like when copying large data (vectors) from one file to another and again when removing a trace from a plot or playing around with a 3D plot? 3.0 was smooth but 3.1 seems a bit cranky?To the best of my knowledge you can't recover a lost file in Prime unlike in M14-15.Manilka

With the operators provided by mathcad, can we create the math operators <a, b> = ...., [A, B] = ...., ect? it does not seem feasible. Do you agree?Otherwise, I would like very much, see clarifying examples.Thank you very much.Sincerely F.M.

I am having slight difficulty graphing this Mathcad problem. When I try, it sends me an error along the lines of "all evaluations either resulted in a complex number or error." The problem is trying to plot the concentration versus position of diffusion/flux through a thin layer membrane. I have to turn it in by tonight, so I would love any help!!Thank you!

This E-book was created in Mathcad 2000i by Martin Zombeck. To install it, create a folder called Astro inside your Handbook folder, where Mathcad is installed. Unzip all the files into the Astro folder, except for the file Astro.hbk. Astro.hbk must be directly in the handbook folder. Astro.hbk and the folder Astro must be named identically for the E-book to work.I have not checked any of the files in current versions of Mathcad, so do not know if they work the same.  I reloaded this file since the self-extracting zip only installe for Mathcad 2001i.Mona

Hi,I have several series of points (x, y) and I have fitted each series in an exponential curve using expfit function.Each series of x and y points has the same z.Now, what I am trying to do is getting a general equation (x, y, z)  to relate x, y and z in one equation.I tried to create a surface with CreateMesh (using regress and interp with all the points, not the fitted curves) but it seems that I do not have access to the equation which links the points. Is it possible to get an equation of the surface?I tried to do something with the fitted curves instead of the raw points but I have not found how to do it. s there a function in Mathcad 15 to do that?I am attaching two files with the fitted curves and the surface created.Could anyone help me?Thanks in advance

Hello,I am trying to write a programme in Mathcad Prime 3.1. I am using the programme to compute the global stiffness matrices of bars in a structural system (just a 6x6 matrix). However Mathcad is returning an error message saying that the expression is too large to be calculated (see attached image). Surely Mathcad shouldn't have any trouble with such an expression. It was outputting correct values until the 4th row at which point it started returning this message.Has anyone encountered this before and know how to work around it?Cheers,Mike

Hey guys,due to my complicated and long Calculation i need to perform certain rowbreaks, so that i can print it on "A4" otherwise i would need "A2" format.Now i have the problem that i dont know how i can perform a "Rowbrake"As seen in attached picture...Is that possible?Thx guys

I'm trying to accomplish the following.  I want to symbolically show calculations along the way to enable basic troubleshooting.  Easy enough, but in the later equations I only want the prior results to be shown, while mathcad prime continues to plop in the whole equation even if it's been evaluated.  Here's my very simple sample.  I'd like to simplify the expression for Ptot by showing the previous results.  But I can't seem to get there easily.  File attached.  Thanks!

This is a process controls question.I am having an issue with creating a program that will place various values into a function while maintaining a variable in the function.Screenshot of what I have written:As you can see, it is only doing the first value for Kc here. I need to be able to call the individual elements of the matrix to graph them. I did a long hand version of this that has the graph attached below to kind of give an idea of what I am after.Of course, I am taking an inverse laplace after the fact as well. Should that also be included into the code or will it be easier to do that after the fact?Any help here would be appreciated, I am not sure what I am missing here...

Hello,Is there a maximum number of nested while loops allowed in Prime 3.1?Thank you,Ken

A right file is attached Dear all,Now I am trying to solve an ODE with double integral operation. I think I have problem with units in the ODE. Could anyone help me? Thank you very much.Regards,Sungyeop

I tested sin function in Mathcad 3.1 and get the following results. Can anybody explain sin function behaviour ?MH

Dear all,I'm trying to solve a PDE that consists of erfc(x) and exp(x^2) like the file attached below, which is simply a poisson's equation.Since it has an unknown boundary condition, F electric field at position x=0, I tried 'minerr(F)' type resolution with F declared beforehand by initial guess.Unfortunatlely, it keeps saying that F in the 'miners' syntax has not been defined.Could anyone can help me?Thank you in advance for your help.Sung

I am trying to make a comprehensive UNIFAC model program and I have it running, except for the user to be able to use this program for any size mixture system, they must edit the component matrices manually. What I want my program to be able to do is, after the user inputs the number of components, a vector is automatically output of the correct size where the user can input the mole fractions of each of the components. Additionally, I need to make a matrix that works in a similar fashion for the user to input the number each type of subgroup is present within each type of molecule present within the mixture.

To organize my Mathcad prime 3.1 solutions, I need to get the filename as a string inside the worksheet itself. How can I get this?

I plotted 24 graphs, but each picture dimension is slightly different, as you can see  below. I would have had to copy the first and paste it each time to plot the other graphs. But having not done so, it would be very useful, in addition to the alignment tools, also a "same size" tool. And I wonder why it is missing?
