Hi everyone.
There is a .dat file, where the first raw of it:
#component = 1 embedding = 1
Then 20x3 matrix of numbers and again:
#component = 1 embedding = 2
So how to remove these lines from matlab when I load the file or is it better to remove from array like:
if x(1,1) == '#component';
x(1,1)=[];

x(1,1) == '#component' will most likely not do what you expect. Use STRNCMP for string comparisons.
What do you want to achieve? Do you want to modify the file or import the data ignoring all lines starting with '#'?

Oh, I solved it:
for i=1:m
if strcmp(temp.textdata{i,1},'#component');
else
x(s,:)=sscanf(sprintf('%s %s %s', temp.textdata{i,:}), '%f');
s=s+1;
end
end
