isinf:

Syntax: isinf ( A )

Description:

	isinf returns TRUE (1) if A is Infinity (according to
	IEEE-754). If A is a vector or a matrix the test is performed
	element-by-element, and a matrix the same size as A is
	returned. 

	Infs can usually be created by attempting to divide by zero. 

Example:

		> a = [1, 2, 3; 4, 5, inf(); 7, 8, 9]
		 a =
		        1          2          3  
		        4          5        inf  
		        7          8          9  
		> isinf (a)
		        0          0          0  
		        0          0          1  
		        0          0          0
