提到了一种解决方案here。 DataHash
功能是解决方案:
function H = DataHash(Data)
Engine = java.security.MessageDigest.getInstance('MD5');
H = CoreHash(Data, Engine);
H = sprintf('%.2x', H); % To hex string
function H = CoreHash(Data, Engine)
% Consider the type of empty arrays:
S = [class(Data), sprintf('%d ', size(Data))];
Engine.update(typecast(uint16(S(:)), 'uint8'));
H = double(typecast(Engine.digest, 'uint8'));
if isa(Data, 'struct')
n = numel(Data);
if n == 1 % Scalar struct:
F = sort(fieldnames(Data)); % ignore order of fields
for iField = 1:length(F)
H = bitxor(H, CoreHash(Data.(F{iField}), Engine));
end
else % Struct array:
for iS = 1:n
H = bitxor(H, CoreHash(Data(iS), Engine));
end
end
elseif isempty(Data)
% No further actions needed
elseif isnumeric(Data)
Engine.update(typecast(Data(:), 'uint8'));
H = bitxor(H, double(typecast(Engine.digest, 'uint8')));
elseif ischar(Data) % Silly TYPECAST cannot handle CHAR
Engine.update(typecast(uint16(Data(:)), 'uint8'));
H = bitxor(H, double(typecast(Engine.digest, 'uint8')));
elseif iscell(Data)
for iS = 1:numel(Data)
H = bitxor(H, CoreHash(Data{iS}, Engine));
end
elseif islogical(Data)
Engine.update(typecast(uint8(Data(:)), 'uint8'));
H = bitxor(H, double(typecast(Engine.digest, 'uint8')));
elseif isa(Data, 'function_handle')
H = bitxor(H, CoreHash(functions(Data), Engine));
else
warning(['Type of variable not considered: ', class(Data)]);
end
此外,你可以找到的代码here的完整版本。

这正是我想要的解决方案。我已经实现了它。 – hyprfrcb
