iscolumn

Determine if an array is a column vector

Usage

iscolumn(A)

• A should be an array.
• It returns logical 1 if A is a column vector, and logical 0 if otherwise.
• A column vector is an $m\times n\times 1\times\cdots\times 1$ array with $m\geq 0$ and $n= 1$.
• This implies ndims(A) == 2 and size(A, 2) == 1
