    while cycle with functions

    Hello, see the following image: (german "erweitern" = engl. "augment") The MathCAD sheet is avaible at: http://home.arcor.de/Chr_Meissner/Public/Forum/Forum_engtips_Matrix.xmcd Christian

    How to execute MathCAD from command line (e.g. *.bat)???

    Thanks @ philipoakley, I'm using the Animation feature very often for periodic (recurrent) calculaions. Normally this works good. But in this special case, it only processes two or three images and then MathCAD gives the described memory error - the evidence that MathCAD does NOT free the...

    How to execute MathCAD from command line (e.g. *.bat)???

    Thank you for your replies. Indeed it seems to be difficult to free the memory, which mathcad has allocated. To get a quick solution, I wrote a little C++ programm which - starts mathcad with a certain *.xmcd-file - reads a certain status file, where mathcad places an idication number after the...

    How to execute MathCAD from command line (e.g. *.bat)???

    Hello, I'm using MathCAD (among others) for manipulating pictures (RGBREAD, RGBWRITE, ...). I've to process more than 2000 bitmaps and I intented to do this over night in a loop. But because of the big image size (1680x1050) the memory limit is reached after 3 files !!! (task manager: RAM...

    Filesoutput of Strings (Text)

    I'm using MathCAD 8. If I write it like you suggested, I get the same answer. Maybe it's because the text is very long. There are more than 100 rows and I dont want to remove all quotation marks. And If I want to display big string-matrices, the computer crashes... Now I try to write this in...

    Filesoutput of Strings (Text)

    Hi, here a unusual question: I have an vector containing strings. Now I want to write them into a file. How can I match that? background: I wrote a simulation of the behaviour of cars while they're driving. Now I want to export the calculatet values into a 3D-graphics-program (e.g. POV-Ray)...

    Does anyone know how to fix this....

    Hello, your second variable "rho" is a matrix with the dimension 1x1 and no skalar (because it stands in brackets). The easiest way to fix this, is to define a new variable like this: p = r[0,0 That extractes the 0,0-element from this matrix and writes it to a scalar variable. That would...

    Mathcad for brainteaser

    @meintsi: You forgot that the original question was WITHOUT brackets (zdas04 from Apr 7). Based on that statement I wrote the program. But I've actual no time to change it working with brackets. Christian.

    converting LaTeX to MathCAD

    Hi! I've a big document written in LaTeX. Now I should convert it into MathCAD. Is there any posibility? Til now, I found a program, with converts MathCAD-htm-code to LaTeX (http://www.tilman.de/mathparser), but I need it in the other direction. I'm using MathCAD 2001. If there isn't one...

    Mathcad for brainteaser

    Hello, are you sure, it works? I wrote it in MathCAD and didn't find a solution. It wasn't "easy" (@GregLocock) but it works. There are 1536 posibilities, no one is doubled and there is no equation with the result 24 (if my program works right). You find the program as PDF at my website...

    Local or global variables in programs?

    Thanks for trying to help me. Meanwhile I found an general option which particulary solved the problem: in the german verion under the menu "Rechnen -> Optionen -> Rechenoptionen -> Berechnung -> Geschwindigkeitsoptimierung -> Rückwärtskompatibilität", in english versions it should be something...

    Local or global variables in programs?

    Hi! I wrote some big programs to describe the dynamical behavior of cars using matrices with submatrices, that means one entry of the matrix is another matrix (e.g. shown in the result as A=([3,1] [3,3] [12,4]). So far this way. I also take references to functions defined in other files using...

    engine output graph

    Hi! I don't know if I understood your (first) question right, but some months ago I calculated the (theoretical) torque over the angle of the crankshaft. It's avaible under: http://service.gmx.net/mc/jGpwpnQScfOkGrO14WD3kEoYL1PVnA You've to chose: "GMX Mediacenter starten" and you can...

    Easy Question -range values

    Hi, I can't find a mistake in your MathCAD-sheet jet. You should get the same value for "Anum" and "O". I only noticed, that "O" ist nearly 180 times greater then "Anum" (a half cycle?). Christian.
