Random Element

RANDELEMENT(ARRAY,N) returns a row of N elements, selected at random (and with replacement) from ARRAY.

[There probably is some toolbox function that does something very similar.]

EXAMPLES:

randelement([0:9],5)
may return [4 8 8 5 2]

randelement({'a' 'b' 'c' 'd' 'e' 'f'},2)
may return {'f' 'd'}
