This function checks whether its first argument is a Maple vector. A vector is defined to be an one-dimensional array indexed from 1.

If the argument K is given, the function checks whether A is a vector with entries of type K .

Also, if K is given, it is essential to quote the word vector in order to avoid confusion with the vector function in the linalg package.

Note: The command vector has been superseded by Vector.
