TEPS Type-based Epsilon Calculation

Section: Base Constants

Usage

Returns eps for double precision arguments and feps for single precision arguments. The syntax for teps is 
   y = teps(x)

The teps function is most useful if you need to compute epsilon based on the type of the array.

Example

The following example demonstrates the use of the teps function, and one of its numerical consequences. 
--> teps(float(3.4))

ans = 
 1.1921e-07 

--> teps(complex(3.4+i*2))

ans = 
 2.2204e-16
