str2cells(someString)

function newCell = str2cells(someString)
%Take a single string and separate out individual "elements" into a new
%cell array.  Elements are defined as non-blank characters separated by
%spaces.  
%
%Similar to str2cell, except str2cell requires an array of strings.
%str2cells requires only 1 string.
%
%Example: Consider the following string in the workspace:
%aString = ' a  b        c  d  efgh ij      klmnopqrs t u v w xyz    '
% 
% >> newCell=str2cells(aString)'
% 
% newCell = 
% 
%     'a'
%     'b'
%     'c'
%     'd'
%     'efgh'
%     'ij'
%     'klmnopqrs'
%     't'
%     'u'
%     'v'
%     'w'
%     'xyz'

% Trim off any leading & trailing blanks
someString=strtrim(someString);

% Locate all the white-spaces
spaces=isspace(someString);

% Build the cell array
idx=0;
while sum(spaces)~=0
    idx=idx+1;
    newCell{idx}=strtrim(someString(1:find(spaces==1,1,'first')));
    someString=strtrim(someString(find(spaces==1,1,'first')+1:end));
    spaces=isspace(someString);
end
newCell{idx+1}=someString;
