iscolumn(V)
iscolumn(V) returns logical 1 (true) if size(V) returns [n 1] with a nonnegative integer value n, and logical 0 (false) otherwise.
Determine if a vector is a column. This example is a row so iscolumn returns 0:
V = rand(1,5);
iscolumn(V)
ans =
0Transpose the vector to make it a column. iscolumn returns 1:
V1 = V';
