function y=odd(x);%ODD	Round towards nearest odd value.%	Y=ODD(X) rounds each element of X towards the nearest odd%	integer value. If an element of X is even, ODD adds +1 to % 	this value. X can be a scalar, a vector or a matrix.%%	X : scalar, vector or matrix to be rounded%	Y : output scalar, vector or matrix containing only odd values%%	Example :%	 X=[1.3 2.08 -3.4 90.43]; Y=odd(X)% %	See also ROUND, CEIL, FIX, FLOOR.%	O.
