: any (x)

: any (x, dim)

For a vector argument, return true (logical 1) if any element of the vector is nonzero.

For a matrix argument, return a row vector of logical ones and zeros with each element indicating whether any of the elements of the corresponding column of the matrix are nonzero. For example:

any (eye (2, 4))
⇒ [ 1, 1, 0, 0 ]

If the optional argument dim is supplied, work along dimension dim. For example:

any (eye (2, 4), 2)
⇒ [ 1; 1 ]
