Mathcad

I have an application where I am using a master worksheet to call functions from several other worksheets. I have just found that if I call a function from an included worksheet which then calls another function from that same included worksheet it does not work and treats the first function as an undefined. Just to clarify I have defined several functions in my Analysis Worksheet, let's call them Function A, Function B and Function C. The Analysis Worksheet is included in the Main Worksheet above the call for all the Functions. What I am finding is that I can call Function A but when I try to call Function B is says that Function B is not defined. The only difference between Function A and Function B is that Function B calls Function C. Has anyone else seen this problem? Do I just have to work around this or is there some way to fix this?Thanks,Justin

  Hello, Everyone.  Need help to create a function U( ) as the above or a similar ?  Thanks in advance for your time and help.      Regards. Loi Le.

How are you supposed to enter domain and range in Mathcad? (I'm currently using Mathcad Prime 2.x).Kind regards,Michael

HelloIn MathCad Prime I always got certain results in parentheses and I do not know why there is this kind of representation and what are the conditions.Kind regards.Denis

Can any one help ?I can find it manually, but 1000 iterations will take very long time

The genfit function works correct with units (sorry, Цена is the Price of an old car, Пробег - a MileAge, Возраст - a Age):he line function works correct:But regress and linfit not correct:

Hello,How can I create assumptions about vector elements?  It seems that my approach below is not working:

  This worksheet evaluates the performance of AC circuit using VB scriptand one slide control acting as a voltage gain control, with multipleinputs and outputs. The frequency range is selected to be (1-10) MHz.The circuit is simply a parallel RLC and a series RLC both connected inseries.The application can be modified to cover many others applications.

I'm slightly confused, can any one see why this will not solve.  I have 4 equations and 4 unknowns.link is attached below.any help would be greatly appreciated.Thank you in advance.I have tried putting all the static values in the guess valueshttps://www.dropbox.com/s/eh8hesqd5t0z9v1/T50047%20Tractor%20imposed%20loads.mcdx?dl=0

Hi, everyone,If I have a 100 by 100 matrix and I want to extract its 10 to 20, 40 to 50 and 70 to 80 rows and columns,Is there a easier way rather than submatrix the rows first and then the columns and use stack or augment to assemble the submatrice?Such as define a index of the rows and columns I want to extract and then extract the index from the matrix in Matlab?E.g, index= [10:20 40:50 70:80]K_BC=K(index, index)Best Shawn

As has been noted many time previously, entering an https address into the M15 hyperlink dialog produces an invalid path/address error.   To add insult to injury, as well as the annoyance of having to remember this when the problem occurs, the dreaded dialog even appears when linking to a Community thread!Given that a simple fix is to remove the "s", why don't PTC just fix the problem (they could release it in M050 along with a fix to the limitation on matrix display size "feature" that got introduced in M040)?Stuart

Why can't I produce this plot in MathCAD Prime 3.1?MathCAD Prime truncates the plot!The prime file and pdf images from Prime and MathCad 15 are attached

how do you add Time. example :  18.00 + 5 hours = 23.00 ??1. how do you add Time. example :  18.00 + 5 hours = 23.00 ??2 how do you con hours to minutes , seconds ?

I'm using matchcad prime 3.1 for the very first time to solve curve intersections as below (which I have a ton of). I know I have to use solve block, but I can get it to work. what am I doing wrongly?y1:=86y2:= -0.0000054527x^3 + 0.010903836x^2 + 0.0714244709x + 74.18816x:=1         y:=1y1(x) = y2(x)y=y1(x)find(x,y)

I'm attaching a simple file that uses AdamsBDF to solve a spring/mass motion problem.  I added units to everything and it worked perfectly, but then I added an "if" statement that generates a ramp function and tried to use it in the D(t,X) matrix and I get a units error even though the ramp function spits out Newtons.You can reproduce the above by toggling which F(t) is disabled or enabled.If you want to look at the file (Prime 3.0 format) and provide feedback, I would appreciate it! 

Hi,The following is the equation in which , the value "f" should be zero, but the integration limit has to change with the y1 value,i.e if y1<z1 the equation will be same as shown,if z1<y1<z2 , then y1 must be in the P2(z) integration limit ,also if z2<y1,then y1 must be in the P3(z) integration limit Keeping the fact that using trial and error "f "must be zero and the equation must change the integration limit as per the "y1" value.                                                                                           &nbsp

So I'm doing some engineering calculations and wants to solve for an unknown in a algebraic expression with only one unknown.Does MathCad have support fort that? It only seems to work when I solve it my self, but not having to throw letters left and right that's why I would want too use MathCad in the first place.I've simplified the problem:http://i.imgur.com/jS3P0qQ.pngThere has to be a way right?

Hi Folks,I think I have an easy question.  I'm trying to transfer MCAD 15 from an old laptop to a new one.  Does PTC allow this?  If so, what do I do?Thanks for your help.Mark

Hello all,Hoping someone can help me save a hours of work by recovering someway somehow a file that froze while saving and now will not open. It was done in Mathcad Prime 3.0. It does have some screen grab graphics inserted into it.

Mr. Sheehan's latest blog on text formatting has me playing, first in Prime 3.0  (we haven't upgraded to 3.1 yet,)then in version 15.  I moved to 15 after I couldn't find an infix function operator in Prime.  You can do the same trick in 15 (without the double quotes.  I typed an a to start a math region, then "cntrl-shift-k" to tell Mathcad that what was coming was a special character, then "alt 0177" to type the ± character.  (That trick works in most places, including right here.)  Then "cntrl-shift-k" again to get Mathcad out of special character mode and parenthesis, x, and y.  Delete the a and you have    ±(x,y)     and you can proceed to define your function,  If Prime had an infix operator, you could do (like 15):

In Mathcad 15 and earlier, there was an inverse temperature unit (actually a post-fix unary operator) for /°F and /°C.  These operators would convert a temperature to the desired units and then strip the units off.   i.e.  if T:=1100°F, then T /°F = 1100 (no units)If I convert a Mathcad 15 worksheet with this construct in it to Prime 3.0, I get the /°F operator/unit in the Prime worksheet and it appears to work correctly.However, this "unit" is not on the Units drop down menu or the Operators drop down and for the life of me, I can't figure out how to type this unit/operator in Mathcad Prime 3.0.  I've tried using T · "/°F" to get the string literal and then removing the quotes and setting the Units label, but I get an error that this has to be a scalar.Anybody know how to do this?  I can't find it in the help system either - it is silent on /°F.

Can I shade the area between 2 functions? Is it as simple as int(f(x) - g(x)) or something more involved?Also I would like to plot the intersect of 2 functions and label the point with coordinates - doable?Many thanks in advanceJoe

I would like to plot directly from a function I've written in Mathcad 15 (MC15) to plot data across values of one parameter, input as either a range variable or a vector, but am unfortunately unable to make this work.  The function, Tsrfc() calls a solve block in a fashion similar to the quicksheet Parameterizing Solutions, and like that example includes units.  Tsrfc() is validated using a thermal analyzer application, but currently works for only one value of insulation thickness, tinsl.  Within the MC15 Area named Geometry examples of attempts to implement tinsl as a range variable [error message: This variable must be a scalar or matrix] and as a vector [error message: No solution was found.  Try changing the guess value or the value of TOL or CTOL] can be seen, temporarily deactivated by a leading underscore, _.If plotting directly from a call to this function in a worksheet is not possible, then I would like to call the function in an in-line program, populati

hello Folks,the first MC15 sheet (find_1) has a solve-block which doesn't compute. The second (find_2), with a slightly different definition, however does. Can anybody explain why this is the case?Tanks in advanceRaiko
