Mathcad

I am trying to solve this equation system and I am getting the below error:    I have checked that all the matrix are 12x1  but I still get the same error. Can you please help me? Thank you very much in advance. 

Mathcad installation and support has to be the most user unfriendly software on the market.  I purchased Mathcad 15 M045 several years ago.  Then I later upgraded to M050.  Then I upgraded my computer from Windows 7 Pro 64 bit to Windows 10 Pro 64 bit.  I had to reinstall Mathcad 15.  If I run the Mathcad license exe file and enter my product code, it says the license is installed; however, there are no instructions on how to access the license.  When I run Mathcad 15, the product code is not my product code but some other product code that the installation used since I could not find any license on my computer.  It would be nice if PTC gave some instructions.  When I go to their licensing tool it says I would have to pay for an account upgrade to use the tool.  What gives with this company.  I have no idea if the product code the installation used is temporary or not.  If it is, I consider PTC now to be a switch and bait company.&

Help I'm trying to do circuit calculations on Mathcad but every time i try to put the units for amps A it shows up as (1/A)*A and cancels out how do I resolve this 

Prime 6 takes so much time to launch. And apparently nobody looks at the splash screen: Now carefully read what "PTC, the PTC logo, and all PTC product names" actually are now... As compared to what they were on a previous release:   Luc

Hello I do not have a lot of experience with mathcad. Please help me!I have to solve and ode which includes some equations. Now I can not calculate it because it says variabe undefined.Why that?

Hello everyone! I´m trying to solve a system of equations with vectors and the solver tell me that there is an error in the array... I put captures so you can see what im doing. Thanks to everyone!

Im trying to get mathcad to find values in a excelcomponet/matrix, but i am having some difficulties with multiple inputs. Is it somehow possible to input multiple values of S in a matrix, and return multiple values from the table shown?      

Hello   I should somehow solve an parameter with iterating several equations simultaneously.   In the attached sheet are to constants, equations and the "to be solved" parameter. The problem is that I don't know if "Given" "Find" system works for this kind of a problem... I would prefer a solution using programming i.e. with "Add line" operator, but I don't know how to program this.   Any help is appreciated.

I have a system of 4 first-order differential equations which can be solved with odesolve.   I want to use the statespace function, but it fails with a cryptic message. My system matrix is not in canonical form, but the documentation for statespace does not seem to require it. I am probably making some stupid mistake, but I don't see it.     Attached are Prime 6 worksheet and pdf.  

Hi Team,I would like to make axial fan flow curve using equation. application is air conditions inlet fan airflow design.please help out make curve with equation, equation should be dependent on radius. If I change radius the curve should be updated as per that.thanks,Madhu

I have an two variable equation.  I want to use one of the two variables as a range variable, and I need to solve the equation for the second variable.  I want to use the solution later as a function of the range variable. Very simplified example of equation I want to solve:  R-T I want to use R as a range variable, but get the solution for T for use later in the work sheet I have attached an example of the two variable equation.  In this example, I solved for D but R is defined.  I want to use R as a range variable and use the solution D as a function of that range variable.

Hi Please, would any one help me and write a code for estimating weibull parameters using the method of moments Thanks

Why is it like this and is there a way to just keep it as "kip"?   Thank you!

Dear all, As briefly described in the object, I’m looking for a solution that allows to convert a “string name” already defined in an Excel sheet to a variable name into the Mathcad Prime 6.0 doc.   Actually, I’m using the READEXCEL function to import string and values that will be used as the inputs for the rest of the Mathcad computation work. With reference to the figure attached, I’m trying to simply associate one-to-one the “meters_var” to the “meters_val”.   I think that working with an external input sheet is more robust to the variation of variable names and quantity and relative values, making the approach more automatic since the Excel formats are interfaceable with most of computation programs.Thanks in advance for your help

Hi,    I've got problem - after reinstalling my OS Windows 10, I cannot acquire express licence, "you have reached maximum number of licence..". I just need symbolic functions to complete term project.   Thanks for response,   JF

I had to reinstall Mathcad 15.  Now it cannot find the help files for either M045 or M050. Any help is appreciated.  This is the error message I get when I click on Help>Mathcad Help or I press F1.         Reg Curry

Dear All,   Is there any option for mathcad 15 to just keep the solution it arrived at before closing (and saving) the sheet for its next use ?   I mean, if I have the automatic calculation turned off, and I have some statements like a:= 5 b:=6 c:=a+b c=11                  (pressing f9 / caluculate shows the answer for the value of c)   If I save and exit, the next time I open the sheet, can I have mathcad directly show me 11 as the value of c (without me pressing f9 again) ?   Many thanks for your time in advance ! Warm Regards, Aravind.  

Not sure why the results at the end are incorrect.  There do not appear to be any mathcad errors.  Any help would be appreciated.

I've got a matrix with i rows and j columns.  I'd like to add all i scalars in column 0 as the 0th element in a new j-element vector, and add all i scalars in column 1 as the 1th element etc.. How?  The column operator seems to require an integer, not a range variable to select the column.  

Dear community,    I am trying to calculate the current I dependent of V of a photovoltaik cell in . To solve this equation I am using the LambertW function. Unfortunately, I ran into two problems that I have not figured out yet:   1. I wanted to define the argument LambertW-function W(z) in symbolic form, i.e. I wanted to type out equation I want to use for z inside the parentheses of the LamberW-function. I made sure that all the units in the function cancel each other out. Nonetheless I receive an error, that "This value has unit voltage, but needs to have unit unitless". If I just solve the argument z of the function the value is unitless. The expression W(z) can be solved though however if I provide unitless variables. I achieved this by dividing each variable by its respective unit, therefore making the input unitless. This bothers me a little though since I haven't found the reason for this problem or how to solve it.   2. I wanted to plot the function W in d

Hi,  I am trying to use solve function to calculate variable's value, but I do not know how to assign this for further calculations.    Please see attached.   Thanks

Hi, I met something strange with symbolic

Five points are known - the coordinates of the asterod approaching the Earth. Will it face the Earth or fly by? (Armageddon (1998 film) ). I have one solution, but I do not consider it the most optimal or the most beautiful. Can you give your solutions. Prime 5 in Attach.

Hello, In the attached worksheet, the FFT of a function is calculated. I would like to get the amplitude at each of the frequencies from the signal. From the plots of the FFT magnitude at various frequencies, it can be seen that the peaks amplitude decrease with increasing the frequency. The plots also show that sometimes the first peak is larger than the second peak and sometimes it is reversed.   I was wondering if this is a natural behavior of FFT or I must modify the script. I greatly appreciate your advice.   All the best, Payman    

Hi I`m trying to make simple calculation but without success. What`s the problem? MC15 file is attached for convenience. Thanks in advance.
