Mathcad

Hello, Everyone. Thanks in advance for your time and help. Best Regards.

I have a MathCAD 14 worksheet that I'd like to reference data from an excel 2003 file into. I'd like to create multiple 21 and 23 row single column vectors with data from various areas of the single excel worksheet. I know where in the data is in the worksheet so I can speciifiy specifcally which specific cells to reference instead of searching for the data from the MathCAD worksheet. I've used the command "readfile" in the past but that seems to only be useful when referencing a single value from an excel sheet. I tried using the excel component but the examples in the help don't seem to be helpful for setting a vector equal to a specific set of cells. My question is how do I set a vector in MathCAD to equal specific range of cells in my excel file?

Does anybody know if there is a documentation of the error function telling why some strings lead to strange behaviour?The effect can be confirmed not only in MC15 but back in Mathcad 11, too - the errormessages are slightly different, though.Its annyoing - ever so often I am not allowed to add pictures to the post. The insert image window would open but never completes showing its full contenet - no buttons, etc.So I only attach the files and maybe I am able to edit that post later adding a pic.Now inserting the image seemed to have worked.BTW, ever so often I see "currently being moderated" flashing at the upper left of my messages. Anybody any information about the moderation done here? I ever so often reply to a thread and after I sent my post I see some other answers which, according to the time stamp, should have been there when I first looked at the thread but they weren't. Time delay as of moderation?

Hello,please scroll down to the red arrow in the attached sheet. i have been able to solve for Pu, using solve. but the issue is i have no control over the number of decimal places, the unit, and be able to use the result for Pu in subsequent calculations. Are there other ways to be able to do this? Thanks!

Hello,i am trying to solve for the variable (e.wall) in the equation similar to what i posted earlier. the result should be in inches or feet. I am not sure if i did any thing wrong. Thanks!

Is anyone aware of how to create a matrix of a data vector using the Jackknife procedure in Mathcad 15?

Hello All,My program returns calculated parameters in a table like the attached picture. How can I address Mathcad to 3D-plot the the first column vs the other columns. How can I recall the data from the dolumns to use them for the next programing stage?Thank you.Payman

Hello everyone, Im trying to find all roots of the equation (2+3i)^(1/4) ...I can find one in mathcad but have no idea how to make it work out all the others (4 in total) and have had no luck browsing the web so really hope you can help me!thanks in advanceKonrad

Hello,Please scroll down in my sheet until you see the red arrow where i have my question. i am trying to maxamize the value for (Lpm_v) so that the ratio at the bottom does not exceed a certain value which i listed inside my sheet. Thanks!

I created a variable in PSI (lbs/in^2)units, multiplied by a unitlesss number. The issue is that my resultant output "Fr" comes up in other format, I just want it to show as PSI, like in the variable. tried "base unit " but nothing changes, please see pic.Thanks

Pipe materials are classified as either rigid (e.g. concrete, vitrified clay, cast iron, asbestos-cement, etc.) or flexible (e.g. PVC, HDPE, ductile iron, steel, etc.).  The strength of rigid pipe is determined by its crush strength.  The strength of flexible pipe is determined by pipe and soil stiffness and is usually evaluated in terms of the deflection of the pipe wall under load.The purpose of these two worksheets* is to estimate pipe wall deflection, using the Modified Iowa Formula, for a single pipe (material & diameter), with a solid wall, in a trench condition, with a superimposed wheel load.  Lusk_Flexible Pipe Design - Range of Soil Cover.mcdx is intended for a complete system design where the cover on the pipeline varies from location to location.  Lusk_Flexible Pipe Design - Single Case.mcdx is intended to evaluate a single location and is thus shorter and simpler to use.These worksheets apply primarily to gravity flow pipelines such as sewers, storm

I'm trying to right a small programming loop to increase the size of a dimension until it passes a certain safety check. Here's what I wrote:All of the OTM values are defined before the function as well as the values for "Code", W.f, FS.OTM, D, a, W.T, D.f, R.p.x, A.p. However, this never produces a value for W.f.new. Can anyone point out where I'm going wrong with this?

I using the default report template and was wanting help with any formatting tricks to get my report ready. Is there a way to make a table of contents? Title Page?

The FIFA 2014 world cup in Brazil is almost upon us and you can almost certainly sense the growing anticipation and football fever that is building around the world. Inevitably the world cup will tend to dominate conversations whether it’s in offices, pubs, with friends in the park, on the train or at home with the family. There is also the obligatory world cup sweepstake to really get you in the spirit. I for one will be supporting England. Recently Prof Stephen Hawking posted an interesting blog on the odds of winning specifically focussing on England’s chances of winning matches in the world cup.Using Professor Hawking’s study we can begin to quantify our chances of success in Brazil. His analysis is based on the results from all 45 matches England have played in since 1966 and all 204 penalties taken in the 22 world cup penalty shoot outs. Using this data he was able to come up with 2 general logistic models linking the probability of England winning a match and a second model for

Hello, Everyone. Thanks in advance for your time and help. Best Regards.

Hello there,I am using genfit to come with the coefficients for a best fit equation for points I have created. However, when I try to plot the graph using the coefficients to see how accurate is the equation as compared to the points in the same mathcad sheet it won't plot. Can someone help me out. I have attached the mathcad sheet. Thanks.

I am new to Mathcad and need a little help.First, does anyone know what this means I understand it is some kind of function. The deltas are displacements.Second, what is a good source for learning more about Mathcad?

How do I evaluate each element in two matrices of equal sizes (4 rows x 5 columns) and then return the maximum value into a new matrix? I want to evaluate each element with the corresponding element on the second matrix and produce a new matrix. Thank you in advance for your help with this!

Is it possible to recover a lost file data in mathcad prime 3.0 ?I wasn't saving my project for about 3 hours and my computer shutdown - the reason is an interruption in the supply of electricity.Is there any chance that mathcad left a dump file? what kind of extension is it and where can i find it? Maybe mathcad run something like file history?Can someone help me? Please it's realy important.Is there any way to prevent this kind of situation? For example autosave ?

HiI try to make a relatively simple program how to find if a point is inside an drawn area or not.The problem is illustrated in the attached calculation sheet.Thank you for your advices in advance.

Hi everybody,I hope I can get some answers here, notwithstanding the fact that I am actually asking more than just a MathCAD question. I tried to put up a MathCAD-framework in order to explain my problem.I wish to compute numerically the flow passing through a temperature-operated valve, of which I know (from supplier datasheet and measures on site), 1) the time constant tau (assuming that it is first order linear system)2) the law giving the flow as a function of the temperature f(T) in quasi static behavior (dT/dt=0)and I assume a certain transient of temperature, T=T(t) A lot of time ago, when I was young and still remembered "Control Theory 1", I would have solved this problem imediatly (maybe!). Now I am a little out of training . Can someone point me to the answer, or eventually if not, to the right forum where to ask for help? Or even to some appropriate literature?Sorry if I am out of subject, I looked for a MathCAD-forum on Control Theory but it does not seem to exist, so I ju

I've installed mathcad on a new computer, and now i need the license. how do i get a license for mathcad through my account ?

One man from India ask me to create some simple formula for steam density. He has given me one template with a, b, c & d coeffs.Look please on the attached Mathcad 15 sheet!Do you have more correct formula for this region of p and T?
