hi,
I have data is formatted as
*cluster1 2 3
cluster2 1 4 5
cluster3 6 7 10 8*
I would like to find way to save it in file, I know textscan work with such format but this function need equal number of columns in each row.
is there any other way to do that?
thanks

I assume that
  1. you want to import data from a text file, which is defined by the three rows embraced by "*"
  2. the "*" are traces of your effort to format the text
Since the rows have different formats textscan is not appropriate.
One way to read the file is to loop over the all rows and read one row at a time with the function
fgetl, Read line from file, removing newline characters
There is an example in the documentation
.
-- Working code [ R2012a, 2012-09-15 ] ---
>> S = cssm()
S =
1x3 struct array with fields:
Cluster
Items
>> [S.Cluster]
ans =
1 2 3
>> S(3).Items
ans =
6 7 10 8
where cssm.m is
function S = cssm()
fid = fopen('cssm.txt');
cup = onCleanup( @() fclose( fid ) );
S = struct([]);
str = fgetl( fid );
while ischar( str )
str = strtrim( str );
str = strrep( str, 'cluster', '' );
num = str2num( str );
S(end+1).Cluster = num(1); %#ok<AGROW>
S(end ).Items = num(2:end);
str = fgetl( fid );
end
end
and where cssm.txt contains the tree rows
cluster1 2 3
cluster2 1 4 5
cluster3 6 7 10 8
.
--- Alternate code ---
>> S = cssm()
S =
1x3 struct array with fields:
RowHeader
Items
>> {S.RowHeader}
ans =
'cluster1' 'cluster2' 'cluster3'
>> S(3).Items
ans =
6 7 10 8
where cssm.m is
function S = cssm()
fid = fopen('cssm.txt');
cup = onCleanup( @() fclose( fid ) );
S = struct([]);
str = fgetl( fid );
while ischar( str )
[ tok, str ] = strtok( strtrim( str ) );
S(end+1).RowHeader = tok; %#ok<AGROW>
S(end ).Items = str2num( str );
str = fgetl( fid );
end
end

Just find help save and load function.
If you want to save data....
Assuming that it is already available in work space.
