Question

I have a data set file that has 3 columns in it.

0 0 1
1 0 0
0 1 0

I have the loaded the data file into MATLAB and now I want to check for which column the output “1” is present.

The name of the file is: out.data

In the first row “1” is present in the 3rd column. How do I write it in matlab?

Answer 1

output = [0 0 1 ; 1 0 0 ; 0 1 0];

[~,index] = max(output, [], 2)
index =
     3
     1
     2
