Hi,
I have cell matrix and I want to identify the rows whose value is negative in the column name "score", and delete entire row if value in this column is negative.

T=readtable('inpudata.csv');
T=T(T.score>0,:)

This works, but in some matlab versions readtable is not available. I want to use cellfunction.
I use below code, but it give error.
index = cellfun(@(x), rawData(:,3), 'UniformOutput', 1);
Error using cellfun
Non-scalar in Uniform output, at index 1, output 1.
Set 'UniformOutput' to false.

The same kind of thing works for cell arrays
scores=cell2mat(rawData(:,3));
T=rawData(scores>0,:)
