or — (|) logical or
or(A), or(A,'*') or(A,'r'), or(A,1) or(A,'c'), or(A,2) A|B
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.
