How to use the index ? how to drop elements from a matrix ?
Ältere Kommentare anzeigen
I have a matrix b(j,w) = b(3,4)
b= [
0.0913 NaN NaN NaN
0.0913 NaN NaN NaN
0.0913 NaN NaN NaN ]
and g(j,w)=g(3,4)
60 60 60 60
70 70 70 70
75 75 75 75
I want to drop the elements in g that have a correspondent NAN value in b.

b= [ 0.0913 NaN NaN NaN
0.0913 NaN NaN NaN
0.0913 NaN NaN NaN ]
c=[ 60 60 60 60
70 70 70 70
75 75 75 75]
idx=any(~isnan(b),1)
c=c(:,idx)

>> g(~isnan(b))
ans =
