Mathcad

Can anyone here tell me why I can not plot the X-Y Point from that DATA TABLE?

Hican anyone here explain, why I get this error`? 

Dear all,long time ago after I did programming MathCAD.How can I filtering on DATA Matrix here for all submatrixes which have conc = 0.5 f.e.I did this but is buggy. Maybe some one can tell me, so that I can remember my knowledge Ihave forgotten. thanks

Engineer here, I need help understanding the limits of my approach. I have a fairly simple electrical circuit, which I can solve very easily by hand - there is only one voltage source which is in series with 3 impedances, and then two external impedance branches.  BUT, I want to simply write the various equations and solve them in an AX=b approach. With the specific impedance values you see above, this approach fails. A is singular, and using lsolve(A,b) in Mathcad reports, "the calculation is not converging".  If I change the bottom left impedance from j1.224 to j1.2 and change the one directly above it from j1.224 to j1.5 I get a solution. But, the lsolve solution differs from inv(A) times b solution and both are wrong.  The current leaving the + terminal of the source will be -j0.30 A by my hand calculation. I've attached a pdf explaining my circuit and a Prime 9.0 file with my simple calculations (I can provide an 8.0 if needed). I'm sure it just

hello community.need some support. im trying to calculate all possible combinations of Voltage * Current need to display all combinations in a matrix with only 1 columnin this case have 3 voltages and 3 currentsmatrix result should be of 1column and 9 rows.  this is what I have up to now, but not been able to display each iteration.  

Hi, I am converting an old Mathcad 15 sheet to Mathcad Prime 9.0 and am working through it resolving errors that have popped up in the conversion. Currently im stumped by an error that comes up with a summation in a program. See attached picture. The program worked perfectly fine in MC15 but in Prime it throws me a "this value must be an integer" error. I've tried backtracking what could be causing the error and the only thing i could come up with is if the error get's thrown in a step where it's trying to summarise from n=460->0... ? However the same formula worked fine in MC15. Kind regards,Johan

 

I developped a formula (thankS to the support of the Community here). The equations are quite long but I suppose for the MathCad engine it should be no problem.It just says the formula is too long to be displayed but it can be used for further calculation  The problem is the following calculations stays grey too and they are not refreshed. -Formula calculation are not refreshed -Quite often I have to kill the task because Mathcad does not answer   Any idea why this strange (and apparently random) behaviour ? Another strange thing is that when it works, the last  formula does not simplify the units, although i defined mm:=10^-3m and gm=10^-3kg Any clue of what is done done properly? Note: I am using Mathcad Prime 9.0.0.0

Hi Folks, I have what I think it s a simple question.  Solve blocks seem to require a bunch of needless space.  Is there any way to eliminate this?  V15 solve blocks were a lot more flexible. Update:  I asked a similar question about two years ago.  I'm just trying to find out whether PTC has made any progress on this. Mark   

Hi,Seems that Mathcad Prime 10 does not allow anymore this. How to do in this case?

Is there a shortcut way of making optional parameters in a function in either M15 or Prime 3.0? I haven't come across anything regarding this issue yet.I ask as this would be a great way to implement the same function with some options. We could use [] to define the optional parameter with the number inside defining the default value.

Hi there,I have a rather long (50+ pages) mathcad (Prime 9) sheet that I have built to be fully parametric. After changing one of the variables I suddenly find that one of the functions is not working as intended without an apparent reason. I have located the source of my problems, but I cannot seem to comprehend why is it throwing this error. I am using root function to solve for the location of the critical x as shown below. In my previous iteration for a different set of input parameters, this function worked as intended, but as I changed one (in this case L, though I doubt it matters too much), I am getting an error that these values cannot be compared even though they are clearly the same unit and allow for algebraic operations such as addition, subtraction etc, but when compared against another variable of the same unit I get this error. If I manually create a new variable, lets say y.crit and give it the exact same value ( through key input ) everything works again, th

Hi,Why is it written that for subscript in text one needs to press ctrl+- and for superscript in text one needs to press ctrl++, while if someone press ctrl+- and ctrl++ it comes out of the way of being able to use subscript and superscript in the text. Is this indication written wrongly?  

Given an ellipse E in the Cartesian coordinate system with the semi-axes a > b and the equationx^2/a^2 + y^2/b^2 = 1. A chord AB of fixed length s < 2*b is considered. Let the point P be fixed on the chord so that the chord is divided into the segments AP = u and PB = v, i.e. u + v = s. The points A and B should now be moved on the periphery of the ellipse in a rotational direction while maintaining the chord length s and its pitch P in u and v. During this movement, point P describes a closed curve K.The content of the annular area bounded by E and K is sought.

Why is the PTC process so convoluted?😫😫  This is the reason I never use PRIME and stick with MATHCAD 15.  I am one of the respondents totally disgusted with PTC as noted on this forum thread.https://community.ptc.com/t5/Mathcad-Installation/MathCad-15-permanent-Product-Codes-no-longer-verified-by-PTC/td-p/815892 In order to help a friend decide on PRIME, I downloaded MATHCAD EXPRESS,  actually PRIME 10 30 day trial.  It supposedly installed because there is a PRIME 10 exe file.  I downloaded the license from my email.  When I try to run MATHCAD PRIME 10 for the 30 day trial nothing happens when I click on the MathcadPrime.exe file in the PRIME 10 folder in Program files.  It never asks for a license; it never installed a desktop icon.  It never showed up in my Start Menu.  Their so called instruction guide is pages long with no succinct summary.  I don't have time to study a lengthy installation guide for such a convoluted p

I was writing up the one of the Mathcad examples for CHAPTER 8: Earth Retaining Structures8.2 Reinforced Concrete Retaining Walls with Sloping Backhill. Could you please help me finding why the error massage was showing up?

  Can you please help me solve this issue? I don't see any faults on equation. Please let me know if I am overlooking at something. Thank you. 

Hello, Please let me know if PTC still officially supports Mathcad Prime 7. Is there any official PTC link where it is stated that this version of the Mathcad Prime software is officially supported? Warm RegardsVijay

Hi,I am making something wrong? Are only 3 differential equations... But using laplace command this system of differential eq can be solved:   See MCP9 file attached.

Good morning,I would like to convert xmcd files to mcdx format.I have Mathcad 15 software and a trial version of Mathcad Prime.The conversion is refused, probably because Mathcad Prime is a trial version.Could anyone convert them for me? I have about 15 files.Thanks in advanceRichard

How I can  tell matcade when the angle is divided by zero consider the value to be zero   

I'm trying to calculate the distance when I do it manually I get different results from the one mathcad givesLp1 should be the same of LP1I also need to write a program to make this function uses different fixed point , for example the first time it will use X1,Y1 (0,0) as fixed point and I get the values for Lp1 the second time it uses x2,y2(2,0) as fixed point and I get the values for Lp2 and repeat the process with the all points to get lp3, lp4 ... and so on

Hello Experts, Please help me with the Subject issue, "How to extract the several Sol Data to one Excel sheet through "WRITEEXCEL" function?" In order to reduce repeated works as I should handle many cases, I want to extract several Sol Data into one Excel Sheet file but no idea :(( Please check the attached mcdx file for the following questions.1. How to get all of the data values(Sol, Fy, y, y1, Fx) highlighted with yellow color in one sheet of Excel file by using "WRITEEXCEL" fucntion? 2. The value of Fx is same for all the variables of each matrix row which shouldn't be correct. Is there any mistake for that? Please give me any advice or solution. will be much appreciated.
