Mathcad

I have two matrices, and I need to generate a third matrix by doing some math as explained in the attached file

Hi, in my sheet i have a set of equations with multiple variables which i have calculated ( around 40 equations). Now I have to solve these equations by equating them to zero in the solve block. I assigned these equations to variables and equated these variables to zero in the solve block. but unfortunately, is not working in the solve block. So now every time i change any parameters in my sheet i have to manually copy all 40 equations to the solve block and equate them to zero in the constraints.Is there a simpler way to do this?Thanks    

Hi guys, I am doing my master's dissertation and i have come across a problem. I have in my sheet Fourier series which is used to show displacement field in this research i am doing. The problem is that by the end of my calculations i have to differentiate a few equations with these Fourier coefficients. I am but unable to do this as in the differentiation operator i am unable to use anything other than variables in the denominator, i am unable to have the index operator in the denominator of the differential equation. I have just started working with Mathcad a month ago. I  have attached two pics to show what i am trying to get at. Any help would be really appreciated. Thank you. 

Hi All,  We have been using this worksheet for a while which in theory allow us to look at different restrain configurations. Its always been a bit flakey, but converting to Prime seems to have finally killed it.  I just wonder if anyone has some advice on how to get it to work?     

I work from home periodically and access my company's network via VPN. Normally this arrangement works fine with Mathcad Prime.  However, every 24 hours my VPN connection times-out and has to be reconnected due to IT settings.  If I leave Mathcad with a worksheet open overnight, then the next day I find that Mathcad has switched to Express mode.  Even after I reattach to the VPN, Mathcad remains in the limited functionality mode.  I have to go through the licensing procedure, re-entering the license server name each day to get back to full functionality.  Is there a way to get Mathcad to notice that the license server is available again and reacquire a license automatically?  (I also use Creo Parametric, and it does this very thing.)    

@TudorMarin @Werner_E how can I make interpolated value of X2 for a specific value of C in Mathcad from given excel or from a mathcad table?    

As per this thread - same issue.   I have the same issue, my old PC died, and now I'm unable to get a new license file to match the new PC HW. I have a perpetual license for version 14-15, but no way to use it - prime is not an option - sorry but I'm not going to pay for a new program that I don't need when I already own a program that covers my needs. PCT, please reach out to me at help me get going again. Thank you! \\\Jens

Unsure if solveblock will work Please help 

Hello All, I am trying to solve an equation that has condition statements and find the roots.Please help, Thanks  

Hello All, I have generated a mathcad worksheet that can find bearing capacity of a soil based on a given footing size. Now, I am attempting to find the bearing capacity based on random footing size and for a given settlement but I am seeing a plotting failed error. Please help. My version Prime 7.0   Thank you 

Hello,i applied for a mathcad student license a while ago when i needed it, but now i want to use it again an the license expired and there is no way to re-activate it?

Hello,I would like to better understand the object "ValuesSetter". Description says it is for setting multiple values of double or matrix scaled values by alias. What does "multiple values" mean? How can a single alias, which is supposed to represent a single mathcad variable hold multiple values?And how is this different from Worksheet methods "SetRealValue", "SetStringValue" & "SetMatrixValue"?If there's someone who could give a sample code in VB using the object ValuesSetter and one of its methods, that would be great.There is also an object called SetValueResults. Is it related to object ValuesSetter? And, does anyone know if it is possible to create a matrix of "strings"? Or mix of strings and double even?The method "SetMatrixElement" of the Matrix object and the method "SetMatrixValue" of the object Worksheet only create matrices of type double.I guess I can send the string one by one to mathcad, then group them into one matrix inside the mathcad but I'd like t

HiI want to extract a column with data from different tables, where each table contains several subcategorys. See example below (and attached file). Is this possible to do in mathcad?  For example, by selecting "Table 1", "Subcategory 3" and section "C" I want to extract a column containing the right set of data.  Thanks in advance!  

Hi All, Working with multiple input data as matirx or vector and  got a error message on function cannot be use here. Root function solve if I rewrite the R into a wx,  Appreciate some advise to see what can be done to solve this multiple combination function by recalling the variable I like to combine in the equation.     

Hi All, I created a set data and put them in matrix. Some data product has return the correct value, but there is not return the total sum of the array. Not sure why this has happen. Please help.    

Dear all, I have a column of values stored in the variable "i". My intent is, I want to utilize a while loop with a continue/break statement to track a specific range of numbers within the column based on a given input row index. For instance, if I input the row-index value of "4", I would like to extract the range of values from the 4th index of variable "i" until the end.  Please help. Thank you 

Hello All, I have a system in which there are "N" number of  black layers and each layer will have random thicknesses.  Then, I want to put a red line on top of any black layer. Whenever I do so, I want to find the number of layers existing only below the red line and also the corresponding layer thicknesses. If the red line ends at the end of the lowest black layer, it should not find any layers below. I can do the worksheet if the red line is present at the top black line but am unable to do so if it stays otherwise. Please help. I have attached my work image for reference. Thank you 

Good afternoon,I have been trying to solve a bondary value problem of a 4 grade differential equation but I don't understand how I should setup up my worksheet to obtain the 3 derivatives (C1, C2 and C3 in in the matrix D_). Also, the function "sbval" returns me an error that says "unkown error: exception by call destination", and so I can't calculate the conditions that I need to obtain the solution. Attached there is the mathcad file in 8.0 version.Thanks to everyone for the help. 

Good afternoon,I am doing an exercise in Mathcad prime 8.0 where I have to solve a boundary value problem of a 4th degree differential equation, knowing that the boundary conditions are: y(0)=q*(R^4)/(64*B_plate), y'(0) = 0 and y(R) = 0, y'(R) = 0. I have tried to setup the worksheet and in r = 0, I have obtained the initial conditions that I need but I can't undestand how I can get the solution to zero when r = R. Also the file attached is written in italian so if you need any clarification ask me.Thanks.  

Greetings all, I am trying to extract value  from a randomly defined matrix but I am unable to do so. I have attached the file and image for reference. Please help.  Thank you, 

Hello everyone, Here I need a help in solving a system of equations in a loop statement.I want to get the coordinates of intersection point of two circles, one circle center coordinate (0,0),R=31.5The other circle center coordinate (33.8 ,S)       -54<S<150how can I calculate all intersection points of two circles using Mathcad. Thank you    

I use matchad prime 8 and for some reason this row operation doesn't work I can't seem to figure out why 

Hi All, I set up an solve block looking to solve a few equation, however the no solution can be found in solve block but when I use root fuction, I manage to get some answers. What have I done wrong? Can anyone spot the problem, please help. Also how do I get rid of the NaN number i.e. 0.6i on some answer in the root function.       

I am trying to find the efficiency of a 3 loop system. In order to find that, I need current equations of all the loops from which I can extract power of the circuit and eventually efficiency of the system. The solution I get is way too lengthy, I tried even manually to simplify them but had no luck.Please help!  

As shown above I have created an table with formula but I want to show the values rather than just formula. please help.Thank you in advance.
