classdef YAML
%YAML Serialize a matlab variable to yaml format
% [ X ] = YAML.load( S )
% [ S ] = YAML.dump( X )
% [ X ] = filepath )
% YAML.write( filepath, X )
% YAML.LOAD takes YAML string S and returns matlab variable X.
% YAML.DUMP takes matlab variable X and converts to YAML string S.
% YAML.READ and YAML.WRITE are convenient methods to load and dump
% YAML format directly from a file.
% Examples:
% To serialize matlab object
% >> X = struct('matrix', rand(3,4), 'char', 'hello');
% >> S = YAML.dump(X);
% >> disp(S);
% matrix:
% - [0.9571669482429456, 0.14188633862721534]
% - [0.4853756487228412, 0.421761282626275]
% - [0.8002804688888001, 0.9157355251890671]
% char: hello
% To decode yaml string
% >> X = YAML.load(S);
% >> disp(X)
% matrix: [3x2 double]
% char: 'hello'
