Hello,
I have a matrix data of n rows(more than 1000) and p columns(exactly six). In this matrix I have a text data repeated each 25 rows. To be more clear I will give you an example:
%row1% Freq X Y Z deltaX deltaY deltaZ
10 20 30 40 50 60 70
1 2 3 4 5 6 7
.......
1 2 3 4 5 6 7
%row26% Freq X Y Z deltaX deltaY deltaZ
0.1 0.2 0.3 0.4 0.5 0.6 0.7
.......
my question is to how import this data and remove the text data. Knowing that I have tried the simple command %
importdata('filename.dat');
but it imports only the first 25 rows.
Thank you in advance for you precious help.
M.

Thank you for your response. I tried this code but it doesn't work: fid= fopen('filename.dat') textscan(fid, 'repmat('%f',1,7), 'F')

You cannot just add the 'F' by itself: you have to use
textscan(fid, repmat('%f',1,7), 'CommentStyle', 'F')
Also note that the repmat() is not quoted.
