Mathcad

In Mathcad 15.0, integration is giving me an answer with units when it should be unitless:The last line shows the function gives a unitless result as expected.

i'm sorry for my bad english I have Mathcad Prime 1.0 on Windows 7 64(bit) Italian.I think that i have found a very fastidious bug.When i write expression and i use the keyboard shortcuts i have a problem for write exponents.If i use the keyboard and i press ( ^ ) ( ctrl+ì )....mathcad prime don't write for example "x^2" but write "x if ||"It's a very big problem for me because i'm so fast with keyboard shortcuts...and i dont' want to use a mouse command and found always manually the correct operator.I see that this problem presents only in math form and not in text form.I try to set english keyboard in windows and now Mathcad Prime work correctly both in math form and in text form....The problem is that i have an Italian keyboard and not an English keyboard.Can You help me??Please it's very important i must use Mathcad for some university project!Bye

I really don't understand why when using a Symbolic Calculation, the value is obtained more accurately than when checking the value normally. What should I do so that the derivative is calculated correctly?   

I tested one new function of Matcad Prime 8 - the reverse conversion of Prime files (mcdx) to files Mathcad 15 (xmcd). Look,please, in the attach, what I got!

I just downloaded Mathcad Prime 7 to see how it would work in converting my Mathcad 15 files. The converter fails and aborts each time, although Prime 7 can still open the Mathcad 15 files (format is not good though). Any suggestions on why this is happening? Many thanks 

How to go back to result with Laplace? I am using Mathcad Prime 6.0

Lets say I have:I want to Weed("v","n","p","h","j") and end up with ["k" "l" "m" "n" "o"] or Weed ("v" "w" "x" "y" "z")So this should take out the first row and I am left with:What would be the easiest way?  

Good day everyone!Some people smarter than me generated some Octave functionality that generates some robotic information that I'm trying to duplicate within Prime. I've been able to get to the point where I've been able to duplicate results within Prime up until a point where Octave is able to evaluate two matrices of various size. I found the following post from 2014 and attempted to implement it but faced challenges:https://community.ptc.com/t5/PTC-Mathcad/Matrix-Division-Mathcad-Prime-3-0/m-p/786608/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufEwxQVdSQ0VGT0pRRUhMfDc4NjYwOHxTVUJTQ1JJUFRJT05TfGhL#M200465 Since I doubt many of you use Octave, I've attached a screen grab of the results calculated in the "Octave.pdf" attached. I'm matching the Octave results up until the division of the matrices. In conclusion: I'm trying to replicate these Octave results within Prime and I'm to the point of dividing the dissimilar sized matrices but struggling from that point on. Can some prov

So I have some Random words:I want them as "v" "w" "x" "y" "x"and "m" "n" "o"  etc. So I madeBut I want it to go through the loops!.I have no idea.

Hi,I have an issue where I have a 5x7 Matrix that I would like to divide each element with the correlating value from a 1x7 vector (element 1,1 in matrix divided by element 1,1 in vector, then element 1,2 in matrix divided by element 1,1 in vector etc.)I.e. to simplify it would be like this:a= [1, 2, 3 4, 5, 6]b=[1, 2]c=[1/1, 2/1, 3/1 = [1, 2, 3 4/2, 5/2, 6/2] 2, 2.5, 3]I can't find the command to do this division (if it exists). Anyone that can help me?BR,Fredrik

See:  https://community.ptc.com/t5/PTC-Mathcad-Ideas/Feature-Suggestion-minimize-gaps-between-long-rows-when/idi-p/750196#M1313   In addition to the above, I've also noticed that Mathcad Prime extends the gap between the evaluation operator and an array when the array is showing the first rows of an array with a large number of rows.   More of a preference thing, but I think it would look better for the gap to be consistent.     Stuart

Hi  Issue with file as below. Prime 7 attached. I can't allocate the values to "Data" without doing the symbolic evaluation.  

I am struggling to get MathCAD Prime 7.0 to multiply two sets of data in order to find a total area. I know that the solution should be simple, but I cannot find the right way to go about getting the program to output the desired information without running into an error.  The question that I am attempting to solve is attached and so is the PDF of my current workings on MathCAD. Any help or pointers would be greatly appreciated!

Hi, do you have samples of real-time graph data of global stocks link to yahoo finance for example any ticker li Apple?  

"Plotting failed. Replace complex values and NaNs by real numbers." Help! Not sure what this issue is here. (Pretty new to prime version of Mathcad.) If someone can take a look, can't tell if something is just formatted incorrectly.

The Minor grid lines and Tick Marks do not appear at all when using Log scale. This seems to be a bug. I do not know how to submit a bug report, so if anyone does - please submit one. Looks like everything about Log scale under Chart component has not been QC’d. I'm using the latest Mathcad Prime 6.0, but I believe this problem will also exist in Prime 5. If so, I can't believe this has not been caught during the last 2 or 3 years that they've put a lot of "focus" on graphing There is also very limited control over the Log plot scale, and sometimes, when playing with Minimum and Maximum under User-Defined Range, the scale displays something completely weird - as shown in attached screenshot. This is probably also a bug.  

HelloI wonder, how the operator ">=" works.As example:I have following termsThe resulet would be 0.922But now i want to add something:I want that mathcad calculates s_k. And if s_k is below 2kN/m^2 it should take the term "2kN/m^2" for sk. If it is above 2kN/m^2 it should calculate it normally like in the first picture. But it says s_k=0. I don't get itI really have no idea how to type this.. I hope somebody can help me  

Hi,   Assume I have a vector of 10*10. How to access one element from the vector in MATHCAD Prime. Say I would like to know 3*4th element in the vector. How to get the same

Good Morning,  I am encountering a problem with the attached file. I have created a sheet that solves siphon flow rate using a solve block. So far the calculator is able to solve for different heights (Z) if you enter this value.  Now what I wish to do is create a plot that shows the flow rates for heights varying between say 1 to 2 meters head. I have defined n number of points and created a function that returns a vector with the different heights in it this vector uses the index k and goes from 0 to n.  Now what I wish to do is run the values for Z through my solve block to get an output (V-out) which corresponds to each element of the vector Z. (e.g solve for 1m to 2m using the increments defined in the second sheet). This way I can create a plot of the values Z against the values V-out and show how the flowrate through the siphon varies with the available head.  Many Thanks,Callum 

Lets say I had a column of numbers (5 digits)71053711871237872678My required function wasf(7,1,’x’,”x”,”x”) =710537 and 71187f(“x”,2,”x”,”x”,”x”)=12378 and 72678f(“x”,x,”x”,”x”,”8”)=12378 and 72678f(“x”,x,”6”,”x”,”8”)= 72678etc What would be the best approach ?

Software installation is overly complicated and I need help with this.  However, when I connect through the chat bot and eventually get to a Case Logger page I find I am unable to actually create a support ticket for a variety of reasons. Please provide a link to where I can create a support ticket, provide an email, or phone number. My last option is to contact my license manager / sales person for help.   Thanks, David

I can seem to find a link or download page - or upgrade button within PTC MathCAD 7.   I already have a license/subscription.  

A funny comparison and maybe a hidden hint for the next Mathcad Prime version ...

Good Morning, I am trying to determine the exact x-location where the maximum deflection occurs. So far I have got a match function:  I wish to return the index k for which the displacement is maximum, the deflections have been calculated and stored in the vector delta-k. With the index found I can then determine the corresponding location where it is a maximum.  I know there are various topics available on this however I have not been able to get it working so far.  Thanks,Callum
