Mathcad

Dear all,Can anyone tell me how to get (from within Mathcad) the name of the folder(s) (not the files) within another folder ?Thanks to good answers from the community I can now read a list of files within a specific folder and also delete the one's which I want to discard.It works very well and I thank the mathcad champion's who answered my questions.I still need to type the name of the specific folder.In fact the main folder comprises many sub folder which themselves comprise the files to delete.May be someone already answered in a file which I cannot open because I have Mathcad 14 and not the last update because I have no administrator rights for the company laptop.Thank youYouki

Hello folks,I've got this weird result in MC15 with the reverse function; see attached work sheet. There you'll see depicted some measurement data and the reversed values. Why on earth doesn't this function behave as in the adjacent example of Q and Y?Any suggestions?RaikoP.S. I'm using MC15 on a 64 bit Win7 machine.

Hi all,I was wondering if anyone knows what internal precision (i.e., how many signficant digits) Mathcad Prime 2.0 carries when a variable is defined. I know that in the Math Formatting tab of the program, the user can change the display precision (up to 16 sig digits). However, once this regions is highlighted it specifically says that changing the display precision does not change the internal precision of the calculation. This to me suggest that the internal precision and the display precision are not "related". I guess the second part of my question (which depends on the answer to that above) is, can the internal precision of variables in Mathcad Prime 2.0 be changed to carry more significant digits?Thanks a million!Pedro

PSIs there a short name ofthe base US pressure units?

Hello,I'm wondering if it is possible to set up a function to calculate the density from the Beattie Bridgeman Equation. The equation is pressure as a function of the specific volume and temperature. P(T,v). However, the answer I want is the density. I can solve it using a solve block, but would like to be able to express the solution as funtion. I.e; rho(T,P) = answer, where I just need to input the Temperature and Pressure. But as seen, the pressure is a function of the density.I have attached the MathCad 15 sheet that has the function, but I'm unsure if I will need to use the mathcad programming to get an answer back in the way I would like. I don't know if there is a way to set up the solve block or solution such that I can have the expression be as above.

Hello everyone,i am student who use Mathcad 15.0 and i am wondering to update on version Prime 3.0. I would like to ask: - is possible to update on full version after school and if will i can to open my school project in full version? - is possible to print projects from student version?Thank you

To all,I am sure I saw something about how to do such thing but I cannot find it so needs some pointersI have a function (see attached mcad sheet) Wm(t,am,bm,cm,dm) where t is time and am,bm,cm,dm are coefficient valid for equation mI need to do sum of Wm from m =0 to n: but I am struggling with indices in mcadCoudl anyone refreshe my memory on this summation? It might be something with "dicretizing" the time 't' if I recallThanksRegardsJXB

HiI need to create a drop down list like this one. I don't know how?Who can help me with this?

I am trying to program a solution to an ODE but I get the message that no "givn found to solve this block". Please tell me where I have gone wrong. I am a beginner in programming. I have attached a file containing the program to solve an ODE. If this succeeds I have a more complicated program involving loops and if statements.

I urgently need a first steps tutorial in Mathcad Prime 3.0 version. I just find older versions tutorials with a completely different interface. Could someone help me ??tks

I would really like to purchase MC 15 in lieu of Prime. I am used to MC 15 and would like to stick with what I am used to. However, I can't seem to find anywhere to buy that particular version of the software. I have a 30-day trial version that appears to be of MC 15, but when I look at the license file it says that it is Version Prime. Any insight or suggestions?

see the attachment file please!

Hello,i have two questions:1. why is the area in the attached mathcad sheet is grayed out?2. i am trying to move the image on page 1 down because it is covering part of the calculation, but i cant seem to have any control to move that region.3. this is a general question, when i print mathcad sheets , some times half of a table shows uo one page and the other half on the next page. i try to shift the table so it is below or above the dotted line for a new page , but some how mathcad shifts it again. is there a better way to have a better control over printing ?Thanks!

HiI install Mathcad on my students labtops. Some of them get the error on the attach file. Whats the problem?

Hi All,This is what it looks like. I was trying to get the real and imaginary part of a big symbolic expression and got the error. I also attached my file Anyone can help on this? Many thanks in advance!Regards,Mingyu

Hello there.I am currnelty explorign the use of the mathcad API for generating a matrix of data from another application.I am using VS2010 Professional and VB.NET. I am using the mathCAD API for doing this. I am using MathCAD V14.0.2.5It appears that there is a limit on the size of the matrix one can create through using the setelement mehtod of the MatrixValue class.My original matrix was of size 6800 rows x 21 cols. When i try and view this matrix or assign this matrix to a new variable MathCAD shows no vlaue for this matrix. Teh matrix is composed of strings - i ahve to use strings as the data is of a variant/object type i.e. strings/doubles/integers. It seemed to crash when I got ro row 480. For rows less than this i was able to view the matrix in mathcad and assign the matrix to a another user defined valriable as well as extract elements for given indices.As a test I simply ran a loop for a matrix of 480 rows x 18 columns and assigned an integer value of 1 for every elment. In th

Many of the worksheets available for download on the community site have PTC Mathcad's read and write functionality within them. These regions will be flagged with a error upon recalculation of the worksheet if the files are not downloaded, saved, and referenced correctly.

hi all, i created a part(like a stike) and its drawing with a broken view in it. when i change the length of the part, the position of the broken view also changed could i use VB API to control the position of views in drawing? like get the position of views and set a new value to put it?

Hi All,This is my first time using Mathcad...... I have this problem which seems to be not hard, however I just can't figure out.......... Would anyone like to help me out here? I've include text explanation of my problem in the attached file.Many thanks in advance!Mingyu

Hi AllI enjoy the units features in Mathcad but find not being able to export them to excel or csv files frustrating. Is there a *simple* way to strip units from a mathcad variable array or matrix in preparation for export via WRITECSV for example?Thanks MuchBill

Greetings,I am trying to build a mobius strip in Prime 2.0I have, what I believe, the equations in x, y, & z defined (found at Wolfram Mathworld), along with the other variable required.The trouble is plotting the equations.Attached is the file with what I have so far.Any clues as to how to build the surface would be appreciated.TIA,P.

Hi all,I completed an introductory course on mathcad a few years back, but these sort of logical problems scrambles my brain, so if anyone could help me out I would be much abliged!I have a problem whereby I have 25 different powder based flavourings of foods, each flavour is made up of a selection between 7-15 ingredients from a range of 51 different ingredients. Set flavourings are directed to three different extruders, 8 of these flavourings are directed to extruder A, 15 to extruder B, and 2 to C.I’m looking to find the number of any combination of ingredients for any setup of all three extruders.I have attempted it in Excel using Pivottable and select the three flavouring individually, which is fine if I need to know a specific setup, but it would take some considerable time to manually choose each combination of flavouring if I wanted to find the combination with the most ingredients. I presume it is possible to display the results in a matrix format where the function was applie

I have imported an Excel file into Mathcad. I want to be able to change values in Excel and then those same values automatically update within Mathcad. I know you can do this with scripting, but I am not very good at writing code. I have attached the files to the discussion. Any help would be greatly appreciated.

The attached sheet poses a question about matrix math; I'm a bit confused apparently about multplying vectors and matrices. The symbolic math seems to indicate that I should get the same answer with either method, but the numeric application shows clear differences larger than rounding errors should allow.What am I missing??
