Determine whether input is vector
isvector(A)
isvector(A) returns logical 1 (true)
if size(A) returns [1 n] or [n
1] with a nonnegative integer value n,
and logical 0 (false) otherwise.
Test matrix A and its row and column vectors:
A = rand(5);
isvector(A)
ans =
0
isvector(A(3, :))
ans =
1
isvector(A(:, 2))
ans =
