Syntax

B = fn_subsref(A,idx1,idx2,...)
indices = fn_subsref(siz,idx1,idx2,...[,'global|local'])

Description

Input:
- A/siz       array, or size of an array (the function guesses that it is
              a size vector if the argument is a vector of size less than
              or equal to 5, therefore, an array A should be larger than
              this)
- idx1, ...   indices in the successive dimensions; can be either numeric
              values (the indices themselves) or strings that are
              interpreted (such as ':', '1:3', '1 3:4', etc.)
              the number of indices specification must be one or the
              number of dimensions of A / the length of siz
- 'global|local'  indicates whether the output indices should be a vector
              of global indices [default behavior], or a cell array of
              indices for each coordinates

Output:
- B/indices   sub-array formed by the elements of A specified by the
              indices idx1, ..., or indices formatted as 'global' or
              'local'

Examples:
- fn_subsref([1 2 3; 4 5 6],':',2:3)   returns the sub-array [2 3; 5 6]
- fn_subsref([1 2 3; 4 5 6],'1','1 3') returns the sub-array [1 3]
- fn_subsref([2 3],'1','1 3','local')  returns the indices {[1] [1 3]}
- fn_subsref([2 3],'1','1 3')          returns the indices [1 5]
