:ref:`any` checks if any elements of a vector
or matrix are zero.

.. function::  r = any(m)

.. us.return

**Return Value**

*r* is a real row vector,when *m* is a matrix. *r* is a
scalar when *m* is a vector or a scalar.

.. us.params

**Parameters**

.. uparam:: m

   is a real matrix, vector or scalar.

.. us.comment

**Comment**

The argument must be real. In order to check if all elements of
a complex vector are different from zero, calculate their absolute
values.

If the argument is a vector, *any* will return TRUE (1) if one or
more elements are not equal to zero (i.e. TRUE).

If the the argument is a mtrix, *any* will return a column vector.

**Example**

::

   * a = [0,1,1; ...
          0,0,1]
   * any(a)
      0 1 1
