How to remove rows with any string from matrix
이전 댓글 표시
Hello,
I'm trying to remove any rows that have any strings in them in my matric, for example:
name and other jibberish
1 0
0 1
0 2
another name and other words
0 3
1 0
other tosh
and change this to just:
1 0
0 1
0 2
0 3
1 0
so you can see, it doesn't matter what the string is, its not specific to what the letters in the string are, I just want it removed. Is there an easy way of doing this?
Thanks

Is your matrix a cell array? Or are you trying to import a text file?

For this, my solution should work.

fid = fopen('file.txt');
res={};
while ~feof(fid)
res{end+1,1} =fgetl(fid);
end
fclose(fid);
res(cellfun(@(x) any(isletter(x)),res))=[]
out=cell2mat(cellfun(@str2num,res,'un',0))
