Hello!
I have the following problem:
I want to extract some numbers from a text file.
Please have a look at this image here, I think this makes my
question clearer:

http://www.villalachouette.de/william/krims/matlabprob.jpg

I want to store four columns in "B". I already managed to
store column 3 and 4 in B, but I do not manage to store
column 1 and 2.

E.g. "0042:0041" has to be divided into the integers "41"
and "41"... How can I do that....?

B.t.w. this is my code to extract column 3 and 4:

A=importdata ('2008-05-6_12-44-18_.txt','\t');
A.textdata (1:13,:)=[]; %delete rows 1-13
B=zeros(size(A.textdata,1),4); %prepare empty matrix
B(:,3)=str2num(strvcat (A.textdata (:,3))); %U vector
B(:,4)=str2num(strvcat (A.textdata (:,4))); %V vector

I am sure that this code is far from being optimal, but it works

It would be very nice if you could help me with this problem.
Best regards,
William (veeeeery new to matlab)...

^^SOLVED^^

sorry, i don't know how to delete my post...

for i = 1:size(A.textdata,1);
X(i,1)= str2num([pixelpos(i,1) pixelpos(i,2) pixelpos(i,3)
pixelpos(i,4)])
Y(i,1)= str2num([pixelpos(i,6) pixelpos(i,7) pixelpos(i,8)
pixelpos(i,9)])
end
