How can delete same rows and colums from three 2D matrices?

Hi All, I have three 2D matrices: longitude (191x177), latitude(191x177) and A(191x177). Matrix "A" contains some NaN values. I would like to delete the rows and colums which contain NaN in A from both matrices. Could someone suggest me a solution? Thank you for your help in advance!

 map=isnan(A); 
 J=any(map,1);
 I=any(map,2);

 longitude(I,J)=[];
 latitude(I,J)=[];

 ind = isnan(A);
 longitude(:, any(ind)) = []; % delete columns
 longitude(any(ind'), :) = []; % delete rows
