how i can find the Union of a particular Binary array???

hello

i have a matrix of 0 and 1 (binary matrix) for example:

A= 

     [001010
      101101
      110010].

so how to find the union of this matrix? what is the mathematical rules of union for binary matrix?

Definition of Union: if any body study mathematics in school, may you could see a lesson about the union between sets, for example: we have set A=[1,2,2,3]and set B=[2,3,3,2] then if we ask what is the union between set A and set B? Answer : A U B = [1,2,3]. the symbol "U" means union in mathematics. (free lesson) i wish it is clear.

What do you consider ‘union’?

What result do you want?

If have

A = [0 0 1 0 1 0
     1 0 1 1 0 1
     1 1 0 0 1 0]

and you want the union along the vertical axis, giving a 6 bit result, then use

   any(A)

Thank you Mr.WalterRoberson

I actually want the union along the horizontal axis. (the Union of each row).

for example the result will be one column with same number of rows:

result= [1;1;0].

[Walter Roberson]

any(A,2)

Walter's solution gives [1;1;1]. Jack still hasn't defined union. Jack, please say how you are getting (mentally) [1;1;0] from that array? Especially puzzling is how the third row is a zero. Please explain.

Possibly, the operation is an inverted XOR, which could be obtained with:

~mod(sum(A, 2), 2)
