struct2var(s)

function struct2var(s)
%STRUCT2VAR Convert structure array to workspace variables.
%   STRUCT2VAR(S) converts the M-by-N structure S (with P fields)
%   into P variables defined by fieldnames with dimensions M-by-N.  P
%   variables are placed in the calling workspace.
%
%   Example:
%     clear s, s.category = 'tree'; s.height = 37.4; s.name = 'birch';
%     c = struct2cell(s); f = fieldnames(s);
%
%   See also STRUCT2CELL, FIELDNAMES.
