SIZE  SIZE Size of a Variable


Usage
 
 Returns the size of a variable.  There are two syntaxes for its
 use.  The first syntax returns the size of the array as a vector
 of integers, one integer for each dimension
 
   [d1,d2,...,dn] = size(x)
 
 The other format returns the size of x along a particular
 dimension:
 
   d = size(x,n)
 
 where n is the dimension along which to return the size.
