Good morning everyone

I'm sorry if I'm asking a simple question, but I would like to create a maplet from a maple code I written.

My first problem is I would like to now how to create a table like in excel, to be fill up by the user of the maplet.

Basically, the maplet will consist of enter two parameters who define the number of colums and row needed for the table,

Then fill up this table, which gonna be plot, and then a button to fit this curve using an equation. And the starting value in order to fit the curve will also be set up by the user.

Thanks you in advance if you can help me to set up this table in the maplet.

cheers!

Hi everyone

I'm stuck with a maple problem

I've got a text file with hundred thousnad of numbers in that form, correspond to point position:

1728
 generated by VMD
  C1        -6.932300       12.540000      -20.260000
  C1        -7.005000       13.914000      -18.431999
  C2        -8.143600       11.942000      -19.424000
  C2        -8.236300       12.972000      -18.327000
  C3        -5.110600       12.270000      -18.719000
  C4        -5.390700       14.318000      -20.143000
  C5        -4.419600       15.242000      -19.368999
  C6        -2.534000       15.407000      -20.941000
  C1        10.458000      -20.974001       -1.023700
  C1         9.977000      -19.162001        0.231220

My problems is, I need to extract specific position, for example, extract all of the position of C1, and put them in a matrix, such as C11(x,y,z),C12(x,y,z)...

in order to be able to extract positions, I currently programmed that:

fileToImport := "metoxyHFtest.txt";

numberreadline := 10;

for i to numberreadline do

lineread := readline(fileToImport);

C6 = sscanf(lineread, " C6%f %f%f")

end do;

Which extract well the position of C6 in that case, but I don't understand how to put these C6 sting in a matrix, even more that each time maple don't find C6, an empty string is produce.

Thanks a lot in advance for your help!

cheers
