or - (|) logical or
or(A) gives the or of the elements of the boolean matrix A . or(A) is true ( %t ) iff at least one entry of A is %t .
y=or(A,'r') (or, equivalently, y=or(A,1) ) is the rowwise or. It returns in each entry of the row vector y the or of the rows of x (The or is performed on the row index : y(j)= or(A(i,j),i=1,m) ).
y=or(A,'c') (or, equivalently, y=or(A,2) ) is the columnwise or. It returns in each entry of the column vector y the or of the columns of x (The or is performed on the column index: y(i)= or(A(i,j),j=1,n) )).
A|B gives the element-wise logical or of the booleans matrices A and B . A and B must be matrices with the same dimensions or one from them must be a single boolean.
