%ISVEC Test if argument is a vector
|
|
%
|
|
% ISVEC(V) is true (1) if the argument V is a 3-vector, else false (0).
|
|
%
|
|
% ISVEC(V, L) is true (1) if the argument V is a vector of length L,
|
|
% either a row- or column-vector. Otherwise false (0).
|
|
%
|
|
% Notes::
|
|
% - differs from MATLAB builtin function ISVECTOR, the latter returns true
|
|
% for the case of a scalar, ISVEC does not.
