Filesoutput of Strings (Text)

Filesoutput of Strings (Text)


here a unusual question:

I have an vector containing strings. Now I want to write them into a file. How can I match that?

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). All commands are listed as strings in a vector and shown right in MathCAD. But if I write them into a file, using    WRITEPRN("D:\test.txt"):=Code    I only get lines with "  -1.#QO".

How can I match that?
Thanks, Christian.

RE: Filesoutput of Strings (Text)

What version are you using?  With ver 11.2a it works for me.  The result needs a little tidying, but basically the text is all there.




Resulting text file:

// Datafile written by Mathcad
// 05/25/05 12:05:42

.MATRIX 0 0 3 1
 "text1" "text2" "text3"

RE: 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 C++ and export only the values from MathCAD.

The file "POV-Ray.mcd" is at my website:
