equality of two matrics having NaN elements

Hi All I have two matrices A and B having some NaN elements. I want to investigate the equality of these matrices. How can I do it? For example: A=[1 2 3; 4 5 NaN] , B=[1 2 3; NaN 5 NaN ] Thanks for your guidance.

Answer 1

[Andrei Bobrov]

out = A == B

OR

out = ismember(A,B)

result:

out =
     1     1     1
     0     1     0

in MATLAB:

 NaN ~= NaN

variant

A(isnan(A)) = 0;
B(isnan(B)) = 0;

out = A == B

out =
     1     1     1
     0     1     1

Answer 2

[Julian]

Consider the following

 >> A=[1 2 3; 4 5 NaN] , B=[1 2 3; NaN 5 NaN ]

A =

     1     2     3
     4     5   NaN

B =

     1     2     3
   NaN     5   NaN

>> a=A

a =

     1     2     3
     4     5   NaN

>> a(isnan(B))=NaN

a =

     1     2     3
   NaN     5   NaN

>> isequalwithequalnans(a,B)

ans =

     1
