iscolumn

Determine whether input is column vector

Syntax

iscolumn(V)

Description

iscolumn(V) returns logical 1 (true) if size(V) returns [n 1] with a nonnegative integer value n, and logical 0 (false) otherwise.

Examples

Determine if a vector is a column. This example is a row so iscolumn returns 0:

V = rand(1,5);
iscolumn(V)
ans =
     0

Transpose the vector to make it a column. iscolumn returns 1:

V1 = V';
iscolumn(V1)
ans =
     1
