I have quite a complicated output file that cannot be made any simpler.
The problem is I need to extract the X, Y and Z co-ordinates from the file for a group of points and store them in an array

The number of points varies from file to file.
A sample of the data file is shown below.

Can someone PLEASE help me?!

One possible template solution:

(look at help/doc for the capitalized functions)

fid = FOPEN
xInd=1,yInd=1,ZInd=1;
xData={},yData={}, zData={};

while(file has more data (FEOF))
oneline = FGETL(fid)
if(oneline[1] matches X)
use x = TEXTSCAN(online,...) syntax to extract required number
xData{xInd} = x;
xInd=xInd+1;
elseif(oneline[1] matches Y)
...
elseif(oneline[1] matches Z)
...
end
end

CELL2MAT to convert the cell array xData to a matric.
....
....



post back if you have more questions while trying to implement this.

Thanks Ashish. Been trying to get something like this to work all day :)
