and
logical and of the elements of an array
Calling Sequence
b=and(A), b=and(A,'*') b=and(A,'r'), b=and(A,1) b=and(A,'c'), b=and(A,2)
Description
and(A) is the logical AND of elements of the
boolean matrix A. and(A) returns
%T ("true") if all entries of A are
%T.
and([]) returns %T.
y=and(A,'r') (or, equivalently,
y=and(A,1)) is the rowwise and. It returns in each
entry of the row vector y the and of the rows of
x (The and is performed on the row index :
y(j)= and(A(i,j),i=1,m)).
y=and(A,'c') (or, equivalently,
y=and(A,2)) is the columnwise and. It returns in each
entry of the column vector y the and of the columns of
x (The and is performed on the column index:
y(i)= and(A(i,j),j=1,n))).
