Mathcad

Hi,I'm using MatCAD 15 and have plenty of RAM. For deconvolution I use a program freely avaiable in the Internet, which runs smoothly on my computer, but after a relatively short time (3-5 min) the program stops working and gives an 'out of memory' error, probably due to an memory leak problem. Can sombody give me some tips avoiding this problem?best Jakob

I am working on a custom function and I would like it to return something like this:In MCADINCL.H, the only return formats defined are:// types to be used in declaration of the function's// arguments and of the return value#define COMPLEX_SCALAR  1#define COMPLEX_ARRAY   2#define STRING 8There is no STRING_ARRAY, is there a way I can do this?Something similar is done in this thread: import data with dat file and stringThanks in advance

Hey,community.I could manage so far the loadcaseprogramming but i have a problem how to get rid with the "NaN" value.At Page 8 of the mathcad file i need the smalest safety factor which i calculate out of the 5 Calculations.BUT WITHOUT THE NAN VALUE. When i do a minimum it shows me always a 0 when NaN occurs anywhere,How Can i write the condition with excluding a zero result?I just want to see the minimum safety factor without the zero.Is there a Possibility to comprimise my programmcode?Best thx 😃

Hey, i do have a problem with the following equation. I need to solve it and find the n value.But i have problems with the units. Can you guys help me?Best thx 😃

Hi all,I have been using  MathCad Prime 3.1 for some weeks: I recently implemented a solve block in which I defined a system of ODEs with guess values and initial conditions: the solution is calculated via "odesolve" function. Since I need to have the time and initial conditions as parameters, I was wondering how to define the solve block as a function, in order to recall it wherever within my worksheet.Does anyone know how to do this?Thanks a lot!Domenico

Dear Expert,Regarding EN_NR1 and NR2 loop statement (left two algorithm), I got a diifferent results from one of Maple software because I guess I might made some fault in the loop but I couldn't find out hence I need your support !!What I want to make in EN_NR1 and 2 is thatinitial value x1,x2,x3,r1,r2,r3  should be updated whenever Xnew evaluate from Jinv with for loop and while loop but It seem it doesn't work... on the right graph from maple software, the black curve doesn't excceed 200 value at y axis but my mathcad say the black curve(EN_NR2) excceed over 1000 value even though the input is same both maple and mathcad.hence Could you support me? Thanks in advanceP.S. My concern content will be located on last page in attached file

I know how to use solve to find an unknown character in an equation, but is it somehow possible to see the equation?I have attached a picture. I would like Mathcad Prime to give me the second equation by typing in the first one.Hope I made clear enough to understand.

I am trying to sum of array elements. can someone help me to do this.the attached picture is extracted from vba.

Dear All,I was struggling with a strange problem in Mathcad. First, I could not change the unit in the result.Second, all the units in the equation are in same format, still it is showing error.Please guide me how can I change the units to psi. I have attached my mathcad sheet.

Im still working on a routine and im stucking in defining a routine for each row of the vector.I need to define a certain condition and apply it to every row of the vectorsThe rows are depending on the Loadcases, which are read in mathcad.I still dont really understand 😞Thx 😃In this case i need to write the maximum value of the calculated 5 pressures to excel for every loadcase.

Hi,I am just now discovering all that Mathcad can do and I am having trouble with solving a system of equations that includes a conditional statement.  If I manually input the statements into the system of equations (at the end), it solves it correctly, but I would like the equations to change based on the selection of LL case.  Any help would be appreciated!Thanks,Nichole

I'm trying to create a title block for a calculation document, but whenever I create my heading with multiple lines the lower lines don't show up in the print, only the top one. Has anyone encountered this issue before?I've attached a little document showing the issue

Hi I want to use the "on error" function to assign a value after an error occurd, however it seems that the "on error" function is not able to cope with an undefined variable, see example. In this case it is obvious that there is no sollution, however I would like to continou with the value 0 (or whatever) if no solution can be found. Can somebody help me how I can tackle this problem?I have also attached the example.

Hi!I am using Mathcad 15 and Excel 2013. I need help regarding this. This problem is only illustrative of the one I want to solve.Suppose that I have a Mathcad file wherein I am embedding an Excel Component. (See attachment).Say if the value of Cell A1 is not "Happy", Picture 1 will be hidden. It will be shown otherwise.Normally, it would be easy to do this in Excel. The code would be:Private Sub Worksheet_Change(ByVal Target As Range)If Cells(1, 1).Value = "Happy" Then    ActiveSheet.Pictures("Picture 1").Visible = TrueElse    ActiveSheet.Pictures("Picture 1").Visible = FalseEnd IfEnd SubNow, I am trying to make this code run inside the Mathcad embedded excel file by coding it there. However, I am confronted with the error:I am thinking that maybe I cannot refer to the embedded sheet as simply "Activesheet."Can anyone help me sort this out?Thank you very much!

can any one help me in finding T.max_2_10k_relief in the attached file i would be happy if the solution is obtained by not using symbolic solver here vonmises stress (sigmavon) is 120000psi

There is sth I miss abt matrix in Mathcad. I have 3 values of yyyd and I insert and compute the value of bb. Instead of computing individually, I put them in matrix and try to get the final answer in matrix. I try two times as shown in the green box but couldn't make it. Any help will be appreciated.Best,

Dear All,I was trying to solve the variable d, diameter of the pipe.I could not get the solution. Can any one help me to solve in mathcad.

I am looking for a way to invert the screen colors or to use high screen contrast colors. Under the Format tab, Colors, it is possible to change the background color, which is helpful. However, I have been unable to find a true inverted the screen colors or high contrast screen colors feature. Any advice?

Hello folks,does anybody know how to turn this oiecewise defined graph into a 3D plot?Thanks in advanceRaiko

please see the attached file and can any one explain me how the variable given T.max_2_10k_relief is not affecting the algebraic equation to get the end result.can some one explain what is going on in the background and is it the correct method to follow.

Ladies and Gentlemen,It has been about four years since I have touched MathCAD. I'm having a little trouble figuring out how to solve for two variables in a symbolic equation. Please see the attached file. This is in MathCAD 15. I've looked through my previous MathCAD files but haven't come up with a resolution yet. I didn't think I needed to define every variable, but I tried doing that and I just end up with 0's.

Hello,I have a quick question.I am using the MINIMIZE and MAXIMIZE function, to find parameters value that optimize a funciton.I am wondering how I can set the solver to find the GLOBAL max or min of the function, or to set to give me LOCAL max or min.Is that possible?Thank you in advanceRegards
