i have a matrix A, and i would like to delete the columns with all cells NaN and the ones with just one valid number
A =
1 3 5 1 NaN
2 3 4 NaN NaN
NaN 4 2 NaN NaN
NaN NaN NaN NaN NaN
NaN NaN NaN NaN NaN
NaN NaN NaN NaN NaN
and i manage to delete some with
A(:,all(isnan(A)))=[] %to al column with all cells as NaN
A(:,any(isnan(A)))=[] %to whatever nan i find

A(:,all(isnan(A)))=[]; % delete columns with only NaNs
A(:,sum(~isnan(A))==1)=[] % deletes column filled with one number
