改写为matlab： item_name = ['idx','seq','lpips'] df = pd.DataFrame(columns=item_name) value = [] s = pd.Series(value, index=df.columns) df = df.append(s, ignore_index=True) value = [] df.to_excel(outpath)

item_name = {'idx', 'seq', 'lpips'};
df = table('Size', [0, length(item_name)], 'VariableNames', item_name);
value = {};

s = struct(value, df.Properties.VariableNames);
df = [df; s];

writetable(df, outpath);
