MATLAB: Logical operators on a logical matrix

logical?MATLABoperators

Consider the following logical matrix of 4X2

A = logical([1, 0; 1, 1; 0, 0;  0, 1])

I would like to apply logical operator (say `or`, `and`) on the matrix row wise so the result is 4X1 vector. (the matrix could of any dimension say mXn, and I want mX1 as output). The `or` operator requires two matrices for comparision, how to do it for single matrix.

Best Answer

all(A,2)
any(A,2)

Try

    A = [true,false; true,true; false,false; false,true];
    sss = sum( double(A), 2 );
    Res = false( size( A ) );
    Res( sss==1, : ) = A( sss==1, : );
    >> Res
    Res =
         1     0
         0     0
         0     0
         0     1

MATLAB: How to apply OR operation to a matrix

Your example is not the 'OR', it is the 'AND', of the columns. The 'OR' of the columns is done this way:

 b = any(a,1);

The 'AND' would be done this way:

 b = all(a,1);
