 Hi everyone!  I'm trying to fit a curve employing a multivariable function (5 variables and 5 parameters), which is a kinetic model. I could write the matrixes but the parameters are negative, and I need positive values. How can I write contraints for those parameters? Here you'll find the file. Thanks!

Puzzle only to fun. Question graphs are made by using Mathcad programing. Divide a surface into two equal sized areas by using matchsticks. 1. With using two matchsticks. 2. With using three matchsticks. 3. With using n>3 matchsticks.

New to Mathcad, I'm trying to understand and provide a long hand example of how mathcad can optimise equations with proof so that I can show the calculations and then move onto solve block at some point.  However, the last steps to rearrange the equation by setting it to "0" and solving has stumped me, in order to obtain the critical points!.  The attached file shows where I've got to.  Can anyone advise how I might expand this and achieve my aim ? Thanks.

How could I remove zeros from the nested array M?, the file generated in mathcad 15 is attached.   Thanks.

Hello,   How can i make the displayed values in the resulting matrix show all the input values, and also show all the resulting calculation to show all the results. if you look at the number of input rows for load is more than calculated value for Load( matrix on right). it shows few dots. I have uploaded mathcad15 sheet. Even the following caluclations in the same sheet have the same issue. I could expand them to show all values.   Thanks, Sam  

Controversial I know, but the free version of Prime is surprisingly good. Hated the idea of moving from 15 but had to with a new job.   How I organise my worksheets is significantly different but I can do almost all the programming I used to do in 15 in Prime Express - don't do anything too complicated - and I think the end results are usually cleaner.   Attached are a few examples I was surprised I could do with Prime Express (V5).

I am trying to acquire a trial license. On the licence wizard login page when I click Next button, I get the error "The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF"

They all have solutions as I checked them manually. I have no idea why this is not working.. I tried changing the guess values to the actual solutions and it is still not working.   Thank you in advance!

No longer have installation CD and when I try to download English version of MathCad 14 (M020) from PTC website, it “errors out” at last minute. Any suggestions on how I can get the installation program for MathCad 14?

Hi,   I have been unable to find a solution online for the problem I am having. I defined a matrix [A:=] with the units of psf. When I restate the matrix with an evaluation [A=], the units are psi. How do I change the units from psi to psf in the evaluated expression? The matrix contains strings and constants (defined with units). I am using an older version (Express Prime 5.0.0.0).   Thank you!

Hello everyone,I have this problem: in worksheets where there are many text areas and calculation areas and some bitmap images, when I select something in a text area and copy it, it happens that the areas overlap, and the images moved downwards followed by a great effort to rearrange everything as before. Is there a remedy for this?Warm greetings to all members of the community and happy new year. Francesco M.

I am trying to solve an equation that has variables raised to a power (x^3) and also has roots (x^0.333).  I have tried to move the dimension under the radicand, but the results still don't work.   Please see the attached worksheet and comment on what can be done for a proper solution.  The answer found in Excel without any units is 4.76 feet.   Thank you for your assistance.

Mathcad Prime installation needs Microsoft.NET 4.6.2 or a later version of .NET that Microsoft certifies is a replacement for 4.6.2So, Mathcad installer ensures that such a version is installed and if not present on the machine, it initiates the .NET framework installation. User cannot skip the .NET installation and proceed with Mathcad Prime installation. It is mandatory to have version of .NET Framework installed   Additional info: Microsoft.NET certified replacements should cover all functions of the previous release and therefore can be installed Different versions of Microsoft.NET can coexist

Mathcad Prime Express shares same installation as Mathcad Prime but provides restricted functionality Mathcad Prime will be launched in or switched to Express mode, in case the Mathcad Prime license is not available For detailed information Refer to Comparison Chart

Hello everyone, In the attached worksheet, I would like to find the number of maxima of a noisy signal. I have observed that the built-in "localmax" function, misses some of the peaks and considers some false peaks even with the window option that could be hard to use with higher frequency signals. To develop the algorithm, I have smoothed my signal using "movavg" and "loess" functions and finally set some conditions to disregard some of the false peaks. However, there is still a difference between the true and extracted number of maxima. In the current worksheet, the true number of maxima in the attached file can be counted 97 but I have got the number 101 so far. I appreciate it if you share your idea and advice on this worksheet. All the best, Payman.
