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.
date Name score categoty rank
20-03-2019 10:24 VAGB -0.12 0 1.0

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,:)
