Hi;

Does anyone has a clue how to delete the string line from the cell array?

E.g.
'---------- GREEDY_CBR_SEED1.STAT'
'2'
'3'
'4'
'5'
'6'
'7'

I need to delete '--------GREEDY........' line from the cell. How can I do that?
I've tried 'strrep' and it does not meet what I'v expected.

Many thanks.

RZee

The same way you delete an element from any other array.

% If you know the element to delete
c = {'abcde', '2', '3', '4'};
c(1) = []

% or if you know the elements to keep
c = {'abcde', '2', '3', '4'};
c = c(2:4)

Tq for your reply. The problem is that I dunno which line the string is. I just read the data from a file and I wanted to remove/delete the string lines and keep the numbers.
I tried below to delete blank lines and it works. Any idea to remove string lines in a file. I do know how to read the files actually.
data = data(~cellfun(@isempty,data));

Assuming your string always starts with '-'

c(cellfun('isempty',regexprep(c,'^-.*',''))) = []

And if not:

c(~cellfun('isempty',regexpi(c,'[a-z]'))) = []
