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.
