Mathcad

hi all, i created a part(like a stike) and its drawing with a broken view in it. when i change the length of the part, the position of the broken view also changed could i use VB API to control the position of views in drawing? like get the position of views and set a new value to put it?

Hi All,This is my first time using Mathcad...... I have this problem which seems to be not hard, however I just can't figure out.......... Would anyone like to help me out here? I've include text explanation of my problem in the attached file.Many thanks in advance!Mingyu

Hi AllI enjoy the units features in Mathcad but find not being able to export them to excel or csv files frustrating. Is there a *simple* way to strip units from a mathcad variable array or matrix in preparation for export via WRITECSV for example?Thanks MuchBill

Greetings,I am trying to build a mobius strip in Prime 2.0I have, what I believe, the equations in x, y, & z defined (found at Wolfram Mathworld), along with the other variable required.The trouble is plotting the equations.Attached is the file with what I have so far.Any clues as to how to build the surface would be appreciated.TIA,P.

Hi all,I completed an introductory course on mathcad a few years back, but these sort of logical problems scrambles my brain, so if anyone could help me out I would be much abliged!I have a problem whereby I have 25 different powder based flavourings of foods, each flavour is made up of a selection between 7-15 ingredients from a range of 51 different ingredients. Set flavourings are directed to three different extruders, 8 of these flavourings are directed to extruder A, 15 to extruder B, and 2 to C.I’m looking to find the number of any combination of ingredients for any setup of all three extruders.I have attempted it in Excel using Pivottable and select the three flavouring individually, which is fine if I need to know a specific setup, but it would take some considerable time to manually choose each combination of flavouring if I wanted to find the combination with the most ingredients. I presume it is possible to display the results in a matrix format where the function was applie

I have imported an Excel file into Mathcad. I want to be able to change values in Excel and then those same values automatically update within Mathcad. I know you can do this with scripting, but I am not very good at writing code. I have attached the files to the discussion. Any help would be greatly appreciated.

The attached sheet poses a question about matrix math; I'm a bit confused apparently about multplying vectors and matrices. The symbolic math seems to indicate that I should get the same answer with either method, but the numeric application shows clear differences larger than rounding errors should allow.What am I missing??

Is there a way in Prime 3 to write partial differential equations?

Hello,after deinstalling a parallel Mathcad 14 installation and registering Mathcad to Net, the converter into Prime 2.0 works but all the OLE components have gone. What are the best options I have to be productive again with both Mathcad 15 and Prime 2.0.PS: I already have re-installed Mathcad 15 without any changes at all.PSS: I did find some hints towards using regall.bat, but this relates to Mathcad 8, what is the procedure with Mathcad 15many thanksbest regards

I have a fairly complex formula for I(q,x) and I want to tabulate the results with q values (1 - 5) as the columns and x values (1 to 5) as the rows. I've no doubt it's very easy, but I can't see how to do it.I apologize if I've posted this question to the wrong forum.

Hello all, I am a fairly new user of Mathcad. I have a question about utilizing units with the polyfit function. I have experimental data relating temperature pressure and density. I wrote a program which needs to look up the density as a function of pressure and temperature. The original data was in excel, it had several curves for a few temperatures as a function of pressure.The data was very linear and the curves were fairly parallel, so i took the linear regression curves from excel and brought them into mathcad. I then created a program which allowed me to choose a temperature, it would then choose the two curves which the chosen temperature was between and linearly interpolated between the two points. I got this program to work with units and is the top portion of the attached file. I thought there must be a better way, so I decided to try the polyfit function. I imported the test data and utilized the polyfit function to "fill in" the holes in my data and create a polynomial to

I am using an excel component with an output to define variables. The variables are then displayed in the worksheet. I am trying to define the units then and it keeps putting 1/m before the mm unit I am trying to specify.See below:What do I need to do in order to correct this?Thanks,Brad

Probably newbie questionIs it possible to input logarithms with a fractional base? When I try it creates a rational expression. Parentheses don't work either. Or, must I change the base?ThanksJoe

Hello,I have a worksheet of about 1.3MB, of which a big part is a program (several pages of code). I have mathcad 15 running on Win7. I tried my laptop with Win7 and the the same happens: when making changes in worksheet (adding a line, editting text or function), I am facing very slow responsiveness. Sometimes I need to wait more than a minute for a single change of adding a letter! Nothing appears on the screen and suddenly a log of a couple of instrutions is done in a sec. I closed all open programs but that did not help. Is there any limitation on the size of the coded program?Any help will be appreciated.Hhussein

In the following attached file, I have to plot a(t) vs t for different values of v like v=-1,-5,1,5. i am getting an error as this variable is undefined. how to overcome it.

We can use units in Mathcad Prime by the solving ODE. It is very good! But I see one error:

I'd like to do calculus on some functions without defining them. When I do this, I don't always get the correct answers. What's the correct way to do this?

I am getting an error as like this also I attached my code below,this value must be a function but has the form unitless mathcad.Can someone say the answer to this. Thanks in advance.

hello, I want to find out the normalization consant in terms of a and p. But i am not able to do that. please see the attachment and help me.

Hello there, Above all, I am the very biginner for Mathcad as well as programming. So please forgive me if my questions would be so basic or stupid. (i am trying. ;;;)Since I have several data to be selected by users, I've decided to use mathcad 15 than prime so that I can make full use of components. I am making a calculation worksheet with a number of back data and I want to know how to syncronize data, like. (refer to the attached also) I have 4 materials for moment having information of size 1&2, parameter 1&2. Some information is duplicated, some is not. Under this situation, I want to program like.. when I select material 1 in the 1st list box (or ribbon which is more favorable), the second list box (or so) shows only the applicable information. the third, forth and fifth.. accordingly. Any advice on this? By the way, I read a forum explaining about list box which was greatly helpful to me and I could hardly understand a part. I've brought a screen shot below and I want t

I'm doing some analysis which at the moment uses an averaged value inside an integral. It's part of a longer chain of calculation and reasoning about a system being designed. At the end I want to have an overall functional form for the performance, so I also undefine each numeric value, e.g. for the wavelength I define l:=l and then I have both symbolic evaluation and numeric evaluation.I also have a signal transmisson 's' integral that currently uses the mean attenuation for the whole of the signal path (i.e. it's assumed constant with range), so the symbolics will 'solve' the integral, rather than leaving the integral intact. Yet I know that we will want to have a functional form for the attenuation with range s(R), so realy I need to be able to retain that functional form, and let the numeric engine handle 'real data' calculation scenariosCan we undefine a function in mathcad? I'm using V15 M030 (MuPad engine), though can use V11.2a (Maple engine) if required.I'll see if I can creat
