    New unit in mathcad

    David, Mathcad simply (?) treats the currency values as being independent of the other units (e.g. see Buckingham's Pi Theorem on Wikipedia), so that you can't express pay (in dollars / hour) in another unit scale (say furlongs / fortnight). If you do it will re-insert a correcting term of...

    Assign symbolic results to a function

    You can simply assign (:=) the result. That is you get: Eqn1:=Solve_my_expression -> Long_results where the 'Solve_my_expression ->' is the bit you already have. It will still give the same message, but Eqn1 will be the undisplayable formula. You can even use My_function(t):=Eqn1-> (long...

    displaying numbers in equations

    There is at present, as far as I know, no method of stopping the explicit expansion at any particular level or for any particular variable. It would be nice if they had a modifier LEVEL1 (rather than ALL) that would olny substitute values for the current equation.

    Solving a System of Equations in Real Range in MAthCAD

    Mathcad can manange some symbolic solutions of non-linear equations, but it is still only a computer programme so can't work miracles. But it can try a lot of methods and approaches so will have a go. It does help if you have a good idea of the sort of answer you would expect. It is easy to make...

    MathCad Collab Down?

    The server is now back. There was a resource overload and it has now been cleaned out. It has stayed up the last few days so it looks solved.

    Surface Plot does not work in Windows 7 32-bit

    There is a 'funny' in that some graphs need the border switched on/off. There's more on the mathcad collaboratory (which is now back after a server overload)

    Recent Engineering Debacles

    Perhaps look at the more mundane "The Design of Everyday Things", Donald Norman and similar ideas. Would a Toaster be allowed if it were a new design (you do remember when you used a knife to extricate the burnt bread when it was still on ;-) - safe as houses, wouldn't be without it. Philip

    Family of curves

    There was an option to change from lines to draw in old versions when using arrays of data. The recent versions dropped 'draw' but won't plot lines going off the plot area, so set the limits just before the end points. It also depends on whether you are plotting a matrix or 3 function...

    Can't Display a Matrix

    "zdas04 (Mechanical)8 Sep 09 18:58 I've gotten help at the Collab, but never without a few "have you always been this dumb?" kind of comments (many were deserved, the "programming" syntax is pretty foreign to me). Don't have time for the abuse today. David " There is always one who gives that...

    Is there such a thing as support?

    Even if you get it automatically, search it out and take a back up.....

    MathCAD XML

    The mathcad schemas are in the directory /schema .... yes you can open the XMCD files ... a) by renaming as .xml and then your browers will display it as 'raw' xml. b) If you have the store images ON (in bloat mode ;-) then there is an image for every region. There was a recent (this year)...

    Greek symbols -user settings

    Background: The 'collaboratory' is the "User Forums" located under the Help menu in MathCAD. This connects to the web site originally set up by mathsoft, and now maintained by PTC. The user forum's web address can be seen in MathCAD by switching on the Address toolbar, or clicking on the 'world'...

    Greek symbols -user settings

    There are a number of threads on the collab that cover the installation of the unimath font. [Occassionally it appears to be 'lost' by windows, or some other process that isn't fully understood, so quite a few posts!] The font can also be embedded in pdf files, given the right settings and...

    From Mathcad to Microsoft Excel

    There is also a collab thread about pushing a value into a particular excel sheet cell. This can be used to drive external sheets that you are not allowed to modify. I think Tom gutman wrote/documented it. It used a short VBscript function. Philip

    MathCAD display formatting

    Use the "explicit" keyword. This is designed to do (show) the numeric substitutions as part of the symbolic capability. Philip

    "explicit, ALL" Mathcad 14 bug ?

    Post in the mathcad collab http://collab.mathsoft.com/~Mathcad2000/expand?99 Mona (PTC) does pick up bugs from that section. Philip

    M020 release conditions

    SSLA said: "I am switching to Maple 13 but need MathCad to be reliable during the transition." What are the relative costs? Are you getting a 'special offer' version of Maple? or just on a 30 day trail at the moment. It would be interesting to hear of the comparison. Philip

    Highlight region color conditional to the results

    There are a number of discussions on ways of (almost) achieving this on the mathcad collaboratory. But nothing as direct as you get with excel's conditional formating...
