Y = all(X)
all(X)
, where X
is a vector, returns 1 if all of the elements of X
are nonzero. It returns 0 if any single element is zero. For matrices, all(X)
operates on the columns of X
, returning a row vector of 1s and 0s.
if
statements
because anif all(A < 0.5)
do something
end
if
wants to respond to a single condition, not a vector of possibly conflicting suggestions. Applying the function twice, as in all(all(A))
, always reduces the matrix to a scalar condition.
