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

collapse all

Determine Column Vector

Open Live Script

Determine if a vector is a column or not.

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

ans = logical
   0

Vt = V';
iscolumn(Vt)

ans = logical
   1
