How do you remove specific rows from a cell array?
显示 更早的评论
I have this 70x1 cell that is made up of my files and looks like this:
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS1.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS1.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS6.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp0\Print.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp0\TS12.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\TS15.csv' }
.
.
.
.
The thing is I want to remove each row that has TS1 in their name, any help? Thanks

One approach:
C = {{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS1.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS1.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp-20\TS6.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp0\Print.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\Temp0\TS12.csv' }
{'myPC\Documents\MATLAB\DataAnalysis\temp\6\TS15.csv' }};
r = cellfun(@(x)strfind(x, 'TS1.'), C);
er = cellfun(@isempty,r);
Cnew = C(er,:)
This takes advantage of ‘TS1’ always being followed by ‘.’. It will fail otherwise.

I did not get that error with the data you posted, and my code.
Without seeing the rest of your code, (the relevant parts of it anyway), I cannot imagine what the problem could be.
Note that you must put 'UniformOutput' in single quotes in the cellfun function.
