Hi,This should look like:   R3 is iterated from high value to low value...    

How to plot this graph and read the Values in Mathcad.

Hello,As I remember I started working with mathcad 2, many years ago.I'm still using Mathcad 15 since 2014.Now I got a new PC and a new Notebook.So I would need new licences.After some Mails I wrote to the academicsupport.The answer:"The Mathcad 15 has retired. We are not able to provide support for this".What can I do now? Is there any chance to run Mathcad 15 on my new computer?Greetings George

Hi,Why I cannot use Trace  Thickness in below plot?  

Recently, my SSD hard drive crashed and I lost all emails and software installed on my laptop, including the license file for my single-user MC 9.0.0.  I can't find a customer support email where I can request a replacement for said license file. Your advice is appreciated. Regards 

In another thread the execution speed of loops was mentioned as a side issue. That warranted some testing. It turns out that using if-construction inside the loop to deal with the first index instead of assigning that before the loop means that the loop takes almost twice as long ... if the loop just assigns a single value to a parameter. If the loop contents are even moderately complex, the effect of the if-construction will soon disappear into noise. Another raised question was the speed of the two forks in the if-construction. From this simple test that is minimal. The random variation is much higher than the difference, but on the average the result below seems to be about right. Another interesting thing, which doesn't show below, is the effect of multithreading. These examples are likely about as bad for multithreading as possible and that was also reflected in the results. The overhead from it was such that each execution time roughly quadrupled from the shown one

HelloI have the next formulae of power but I think  there is an mistake, Please somebody help mePot=(PxQ/360)/1.358P pressure in bar=225 barQ flow in l/min=78 l/min Pot=( (78*225)/360)/1.358=35,8kW Thanks

Hello Everyone.From : Need help with the trimZeroElements( ) program function with ORIGIN := 1 and ORIGIN := 0 ?Thanks in advance for the time and help.Best Regards.Loi.

I wrote a program and it works properly. The only problem is that it starts from the second value in the matrix not from the first value. How can I solve this problem?, The problem is in layer 1

HiI want to calculate/plot the deflection and the moment along a column (or a stand-up beam) subjected to a lateral point load. The column is pinned at the top (A) and fixed at the bottom (B), and the load P is acting at a distance a from the top. If somebody can bring some knowledge to this, I'll be very thankful    

For those who still use it, I encountered some strange behavior in the symbolic operations of mathcad 11.2a. In my decades of using mathcad, I find it hard to believe I hadn't seen this before. Using a unary negative sign in front of a vector evaluation seems to work as expected both numerically and symbolically. However, if the unary negative vector is added to another vector of the same size, the result is a nested array. I can't figure out what is going on. Am I just missing some expected behavior, or is this a bug? Lou

need to find q1 which is basically the values of qcza( known variable) qcza is the resistance in known depth [z]. q1 is equal to qcza when the depth is between 0.7D<z< 4D when D=0.4 and it has always to choose the minimum value until there is smaller value. the file is attached

I have z values and I want to specify an interval from the z values. I want to say that the values of layer 1 are the vales between 0.7d<z <4d when d = 0.4m .

Not a question of mathcad but Mathcad can solve this. Find the Length DE. ABCD is rectangular. 5 areas are same sizes. AB=13 cm.    

Help me please with this problem! Thru ODEs solution - see please the attach Prime 9 file. See also Great-Comet-of-1811-ODEs-solution 

I need to make mathcad to choose the minimum value when it draws the plot. The next value can't be bigger than the previous value?Please Help  

Hi.First post, LONG time mathcad user...on prime 9 now.I'm trying to fit a fairly routine function to some datapoints using genfit.I don't see where this is going wrong.genfit basically treats the guess value for 'a' as a hard constraint.So whatever I set the guess value to ('3', below), the fitted function asymtotes to that value and does not adjust 'a' to fit fit the data. What am I doing wrong?Many thanks in advance. 

Building stiffness matrix I needed a function to add one smaller matrix within a larger one. I've added some functionality to that just out of interest. Now the second one can be added or it can replace the first. It can also be fully or partially outside the first and the original matrix can either expand or the latter matrix can be cropped. Seems to be ORIGIN-neutral too. No guarantees, so test it first. Have fun! Mathcad is Prime 9.

hello,im trying to get best wey to round numbers with units like 5.123456789 V im using the function round(x)but shows error for units not compatible need to use the rounded value to show on summary resultsright now im using this functions to round and display the results   but this basically remove the units and convert my variable over and over to number and string, to be able to display it as result.as you can see below but i want to show that result is actually 3.33 V I also have calculations for current, and capacitance, so I need function to keep different used units. 

I want to insert huge table with 1339 data in mathcad without using excel . I need the values to be in the mathcad sheet but I don't want to have many pages. Is that possible? I don't want to have 38 pages  Can I just show the first ten rows ?  

Has anyone managed to install MathCad 14 on Windows 11? I thought I had done it, but various things are not working. For example (this is from my from my Windows 10 installation) On the Windows 11 installation i =  produces nothing; i.e. no table.  

Hello, I tried to download Mathcad Prime 7 but in the installationassistent the status of the application is "not permitted". How can I avoid this? 

Hello,  I am using PTC Mathcad Prime 9.0 and really need to extract the all values of Sol Data of differential equations in Mathcad to Excel or CSV files.I can only do make the graph with the data.Your help or advice for the method will be very appreciated. Thanks

Dear forum,Does anyone know what the error is and why it doesn't give the result I expect?Regards,CarlosRomero
