1. For each element of matrix "Em", it is required to match only one closest value from matrix "E_exp_int".Corresponding to that matched element of "E_exp_int" it is required to lookup flow and obstruction values in "flow_int" and "obstruction_int" matrices.The looked up elements of flow_int and obstruction_int will be used for calculating variable "status", as shown below. Right now, there are just flow and obstruction matrices only.2. The summation corresponding to index m starts from 0. For m=0, a constant "lateral_coeff" will be used in place of variable "status". Then, first term of summation needs to be given half weight.  

Hi all, I am putting together a calculation sheet where the input data is entered using the Excel component. The first column is the thickness of my layers, called h. In the "Outputs" section of the Excel component, I define h as having a range between cell A2 and A21 (so maximum number of layers is 20). However, if the user enters less than 20 layers, I wanted to give the option to not have to change the range definition so I was using a filter function to remove all non-defined values of h as follows: h := filterNaN(markNaN(h,match(0,h))) This works great; for example, if I define 9 layers, I get a vector length of 9, even though up to 20 layers can be entered. However, one of the other input variables, called OCR, applies to some layers and doesn't apply to others. For the layers that it doesn't apply to, I enter "NaN" in the cell to show that it is not applicable as below: h (m)OCR0.520.520.520.520.5NaN0.5NaN0.5NaN0.5NaN0.5NaN However, if I use a similar fi

Hi! Can u convert this file, pleasse! I can't convert them in Mathcad Prime option. Thank you!

Hi allPlease, see the attchd.file, mathcad prime 3.1.There is a graph where I would like to have parameters y and z related to x axis scale and parameters y2 and z2 related to x1 axis scale in the same graph. I have absolutely no idea how to define which x coresponding with which y for plots where are a several different x.Does anybody have an idea how to do that?Thx a lotRosta  

Hi MastersHow to reassign the array elements order??tks  

Hello Community,I would like to make a project with mathcad simulating the old Mathcad Calculation Server.That is, I want to set up a Mathcad on a server and from a client computer to be able to have an HTML in which I enter values and give me the result.And finally you can print the PDF of the Mathcad spreadsheet.I put a scheme as a graphic example: All this can be done without installing Mathcad on the users' computers.Does anyone know a similar example and can help me.Thank you,Jordi.

Hello, I'm trying to put this table in MathCAD:The goal is to have a function that will let me input just ADT and Design Speed, and then give me Runout Length. What is the best way to do this? Thanks 

Good Afternoon, I created a design template for a steel diaphragm.  I completed the template yesterday and saved the file and restarted my computer. Upon trying to open the file this morning, the file will not open.  I do not get any error message when trying to open the file, rather the MathCAD splash screen pops up an then the program shuts down.  I cannot locate any backups or other versions of the file stored locally.  Is anyone able to help recover this file for me?  I am not sure how best to do this.  The file is attached.  Thank you in advance for any help with this! 

I am trying to type the following into Mathcad for a lab:   I can define F1:=(f1*cos(a1), but when I press enter to input the second function, Mathcad exists the math block. I have tried searching numerous forms, but have not found an answer on how to type this in. Ultimately it should produce the following: Any assistance would be greatly appreciated. I am working with Mathcad Express Prime 8.0.0.0        

I'd like to see more than four significant figures.   Can't seem to find a setting that would enable more significant figures from calculated values.

Hi all, I am trying to use Mathcad to symbolically carry out the 1st, 2nd and 3rd differentiation of a function with a stepped component. The first differential of the function yields plausible results. The first differential has the signum function. When I integrate the first differential result into my actual calculation sheet using the built in "sign" function instead of the signum function, I do get plausible results and the units are consistent.Here is the function and the first differential:However, things start getting a bit complicated with the 2nd and 3rd order differentials. Here is the 2nd order differential: As you can see, the symbolical evaluation of the second differential leads to the signum function raised to the power 2 and now I get a new DELTA function. From the help, I understand this to be the Dirac Delta function. However, I am not sure how to integrate this DELTA function into my worksheet. I understand that I have to change the DELTA to small delta (K

Hi All, Try the disappearing worksheet trick, From the help menu lsolve() is supposed to work on complex variables Solving Linear Systems•lsolve(M, v)—Returns the solution x for the linear system of equations M·x = v, using LU factorization.Arguments•M is a real or complex matrix. If the matrix is square, it must be nonsingular.•v is a real or complex vector or matrix having the same number of rows as M. See the enclosed sheet just before the crash.  put an evaluation equal sign after lsolve(A,b) and presto Prime vanishes with no warning or error.        

I have been using MathCad since the late 1980s.  I am now retired and no longer have access to Mathcad 14 which I used with my old company. I want to access some old files.  MathCad Express will not let me convert them.  Is there another way to access the files?  I had a 1990 version of Mathcad but no longer have the ability to load it on my PC.    

How do you type subscript lettering while in text mode?

Hi Masters.There are having the known series of Ipk(t), Ton(t) and Toff(t).I would like to draw a positive slope of straight-line which connects between the origin and Ipk(t) in Ton(t)and a negative slop one which connects between Ipk(t) and the end of period.     How to plot the inductor current by those series? Is the way of using coordinate series?tks    

Hello Everyone.From the following :Given :Let four contact-points of a side and incircle, excircles of a triangle are the pink point, green point, red point and blue point.Prove :Distance from the pink point to the red point = distance from the green point to the blue point . ( see figure ) Thanks in advance for your time and help.Best Regards.Loi.  

Dear forum, Basically, I am trying to analyse the forced vibration of a single span Timoshenko beam on elastic supports at both ends. I want to at the end determine the displacement w(f), rotation phi(f), shear force Q(f) and bending moment (f) at the ends of the beam due to a force excitation on one end of the beam. I want a plot of these paramaters over the excitation frequency f = 1Hz., 2Hz, 3 Hz....1000Hz. To obtain these parameters, I need to solve for a matrix system which looks like this: A.c = b. A is a 4x4 matrix for each frequency, c is a 4x1 vector for each frequency and b is a 4x1 vector for each frequency. So, based on my frequency spacing of 1Hz from 1Hz to 1000Hz, I have 1000 4x4 A matrices in the A(f) matrix, 1000 4x1 matrices in the c(f) vector and 1000 4x1 matrices in the b(f) vector. I have tried using lsolve to solve the system of equation for the c(f) vector but I keep on having an error message which says that the calculation does not converge

Again, here I am asking for help in animating a chart. I can't get a moving dot/symbol moving on the red curve. In particular, I am not able to successfully define the symbol and its movement parameters in the diagram.Kind regards, Alfred Flasshaar

Hi all, I'm somewhat new to MathCad. I'm trying to use a solve block to find a solution to several co-planar triangles that have some common sides/angles.  I've got it drawn up in CAD so I can check my calcs.   In the attached sheet, everything up to the solve block is verified.  I ended up with ten variables and ten equations.  I entered all this in a solve block (very bottom of the sheet).  I'm getting a "These units are not compatible" error.   It's possible my math is wrong or that some of my equations are redundant but before I dig into that, can anyone see any obvious error I made? Like in the syntax or units? Thanks,    

I have a wide document. Whenever, I expand an area and the tool moves the horizontal bar right to shown more of the right hand side of the document. This then hides the Area expansion buttons. How can I prevent the tool from doing this? We have documents with lots of expansion areas so this makes it difficult to navigate the worksheet since it moves about on you and requires constantly moving the horizontal bar left again to browse all the Areas.  

Hello,   MC Prime 8 file attached. Thank you.  

I have defined every variable except for Lb. I thought with it being defined as an independent variable in the function, Mathcad would understand to vary it from 0 to basically infinity. If not, how do I define Lb to work like that. Thanks.   

First, let me put my flak jacket on under my flame retardant suit...   I still have my 5-1/4" disk of Mathcad 1.0 from 1987.  I LOVE Mathcad.  It has served me well my entire career.  For a long time I have been right there with the other Mathcad 15 zealots on this forum.  I had the opportunity for a face-to-face meeting with the Mathcad product managers and developers about 10 years ago in Latham, MA and I told them across the conference table, "Until Prime can provide the basic requirements of a high school 2D plot (Title, labels, legend, readable axis, etc.), Mathcad Prime will be nothing more than a toy!".   There was palpable silence in the room, I can tell you.  Reflecting back, I was seriously angry because I could see that my beloved Mathcad was coming to an end and the only replacement for it was inadequate.   Then I waited.  Ten years.  Nothing.   I teach a corporate Mathcad course to get our engineers to use Mathcad
