Delete rows in cell that contain part of string

16 visualizzazioni (ultimi 30 giorni)
I have an Nx2 cell (mixes of strings and doubles) that I'm trying to clean up (rawdata). Specifically, I am trying to delete all rows with ">" in the first column. My code below is deleting those rows, but it is reshaping the cell as an Mx1 cell (data1). I'm not sure where the error is. Thanks for any help.
rawdata = textscan(fid, '%s %s' , 'HeaderLines', 7);
rawdata = [rawdata{:}];
data1 = rawdata(cellfun(@(s)isempty(regexp(s,'>')),rawdata));

Cell(strcmp(Cell(:,1),'>'),:)=[]

Example with 2-by-2 cell array:
Cell = { '>', 123, 'abc', 'xyz'; '2abc', 456, '>' 'str'}
Cell = 2x4 cell array
{'>' } {[123]} {'abc'} {'xyz'} {'2abc'} {[456]} {'>' } {'str'}
Cell(strcmp(Cell(:,1),'>'),:)=[]
Cell = 1x4 cell array
{'2abc'} {[456]} {'>'} {'str'}
Note that row 1 is gone because the first cell in that row is '>'.
Not sure how certain you are that the > contains no white space but you may make it more robust by using strtrim and/or startsWith, for example if the > was the first non-white character and had other characters after it, you could do it this way:
Cell = { ' > ', 123, 'abc', 'xyz'; '2abc', 456, '>' 'str'}
Cell = 2x4 cell array
{' > '} {[123]} {'abc'} {'xyz'} {'2abc' } {[456]} {'>' } {'str'}
Cell(startsWith(strtrim(Cell(:,1)),'>'),:)=[]
Cell = 1x4 cell array
{'2abc'} {[456]} {'>'} {'str'}

Below works, but perhaps is not the most elegant code.
rawdata = textscan(fid, '%s %s' , 'HeaderLines', 7);
fclose all;
rawdata = [rawdata{:}];
idx = strfind(rawdata(:,1),'>');
tf = cellfun('isempty', idx);
tf = [tf tf];
data1 = rawdata(tf);
data1 = reshape(data1,[length(data1)/2, 2]);
