Mathcad

Hello @Werner_E and crew,I've recently returned from a hiatus from the forum due to a busy schedule.I'm back with a new project and seek your guidance.I'm presenting the following scenario: I'm dealing with three rectangles or zones: A, B, and C. Each zone has a priority level. I have a list of points that I need to plot and require the program to determine the zone in which each falls. Should a point land on the boundary shared by two or three rectangles, the program should assign it to the zone with the highest priority. I've been working with Mathcad Prime 9 and have devised a solution, but I feel it's lacking because I haven't effectively incorporated the priority level. Could you recommend a more refined approach? Below are snapshots for easier reference. In the real world scenario, there will be many more zones and huge list of points.  

I am using Mathcad Release 15.0 and DatecodeM050Need to plot circular segment for four different cases. Need help setting up. see page 19Sheet one dose it individually, Sheet two wit T on name is my attempt to do this. See page 19.Here are the errors that I facedSee sheetDon't know how to upload my sheets.

A cylindrical cake (torte) has a chocolate icing. A knife is used to gradually cut out pieces of cake with the angle alpha and then flipped over and reinserted into the cake so that the icing is on the bottom. We keep doing that - after one circuit, the cuts can end up in pieces that have already been cut. Of course, the glaze moves back up, ...If e.g. alpha = Pi/2 (90°), then after two turns the glaze is completely on top again.Question: For which angle alpha is the glaze completely up again after a finite number of steps? Friendly puzzle greetings!

can anyone please help me with following: Worked well in Mathcad 15, Prime 9 doesn't like it... Best regards   

I would like to define a variable as [η] but typing the square bracket initiates a matrix definition.

Hi, I am new to Mathcad and have just learned the feature of collapsible areas. Now, does anyone know how to reduce an unwanted area within a defined collapsible area? Understad the inserted area automatically increases to accommodate more content as writing. But when I remove some of the content, it won't shrink, leaving with a large unused space in the worksheet. I couldn't find anywhere one could manually drag that area to reduce its size. Does anyone come across the same problem? I'm using PTC Mathcad Prime 9.0.0. Regards,Frank

Hello, Expert guys in this community. Recently I have received help to solve the problems in using Mathcad Prime 9.0. Appreciate it. However, since I am just beginner level guy, I am having difficults with ODE solutions.(In addition, if you can solve those equations with AdamsBDF, then pleas add it) Please check attached worksheet files. Your help will be very much appreciated. Thanks!!

Has anybody seen this before: I consider it a bug. (Attached file is Prime 4) Luc

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.

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

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.
