6 % DESCRIPTION: STR2CELLS Take a single string and separate out individual
7 % "elements" into a new cell array. Elements are defined as non-blank characters separated by
8 % spaces.
9 %
10 % Similar to str2cell, except str2cell requires an array of strings.
11 % str2cells requires only 1 string.
12 %
13 % CALL: newCell = str2cells(aString)
14 %
15 % INPUTS: aString - string
16 %
17 % OUTPUTS: newCell - cell array of strings
18 %
19 % EXAMPLE: Consider the following string in the workspace:
20 %
21 % aString = ' a b c d efgh ij klmnopqrs t u v w xyz '
22 % newCell = 'a'
23 % 'b'
24 % 'c'
25 % 'd'
26 % 'efgh'
27 % 'ij'
28 % 'klmnopqrs'
29 % 't'
30 % 'u'
31 % 'v'
32 % 'w'
33 % 'xyz'
