MATLAB: How to remove from a matrix only those columns whose all elements are either NaN or zeros

Question

I'm using R2016b:

An example of matrix:

A = [...
       NaN    0.2200    0.2400       NaN
    0.1400    0.2000    0.2600       NaN
    0.1400       NaN    0.2600       NaN
    0.1400    0.2200    0.2400       NaN
    0.1400    0.2000    0.2600       NaN
    0.1400    0.2000    0.2800       NaN
    0.2200    0.6200       NaN       NaN]

I want to exclude only column 4.

I tried ( from Andrei Bobrov on 25 Mar 2013):

out = A(all(~isnan(A),2),:); % for nan - rows
out = A(:,all(~isnan(A))); % for nan - columns

but they also remove all rows or columns with a single NaN element.

Thanks in advance.

Answer 1

I just find the solution for my question from Saman (on 23 Oct 2013);

I guess it is problem related to the version of Matlab. I just had to change the "all" from Andrei Bobrov (25 Mar 2013) below, to "any", as suggested by Saman.

Therefore:

out = A(all(~isnan(A),2),:); % for nan - rows

became

out = A(any(~isnan(A),2),:); %for rows

and

out = A(:,all(~isnan(A))); % for nan - columns

out = A(:,any(~isnan(A))); % for columns

Thank you.
