试试这段代码：
aux = char(factor(sym('12345678901234567890'))); % convert to string
aux = regexprep(aux, {'*'}, ''','''); % replace '*' with '',''
result = eval( ['{''',aux,'''}']); % evaluate string expression
% Separate each string into tokens around the '\^' character
factor = cell(1,length(result));
exponent = cell(1,length(result));
for i=1:length(result)
factor{i} = regexpi(result{i}, '(\w*)\^', 'tokens');
if isempty(factor{i})
factor{i} = result{i};
else
factor{i} = char(factor{i}{1});
end
exponent{i} = regexpi(result{i}, '\^(\w*)', 'tokens');
if isempty(exponent{i})
exponent{i} = '1';
else
exponent{i} = char(exponent{i}{1});
end
end
% Converting the cellstr to normal matrices
factors = zeros(length(factor),1);
exponents = zeros(length(exponent),1);
for i=1:length(factor)
factors(i) = str2num(factor{i});
exponents(i) = str2num(exponent{i});
end
clear result factor exponent i aux;实际上解决方案类似于Kokbira的建议。
希望能帮助到你，
