i tried to use textscan but i don't really understand how to and it looks a bit complicated

any other solution or how to do this?

Answer 1

[per isakson]

Try

    cac = textscan( fid, '%*f%*f%*f%f%f%*f%*f', 'Headerlines', 10 );

Doc says: &nbsp %* &nbsp Skip the field. textscan does not create an output cell for any field that it skips.

That's not too complicated!

"any other solution or how to do this?" &nbsp None less complicated than textscan - AFAIK

dlmread() would be easier if it only had a headerlines option. With textscan() you also have to call fopen() and fclose().

Maybe try importdata()

delimiterIn = ' ';
headerlinesIn = 10;
myStructure = importdata(filename,delimiterIn,headerlinesIn);
data = myStructure.data;

Worked for me.

You could do it all in just 2 lines instead of the 3 required for textscan(). Plus you don't need to figure out all that stuff about '%*f%*f%*f%f%f%*f%*f' since it figures it out for you.

Problem is I don't know about importdata ;-).
