csvname='xxx.csv';
columns = {'A', 'B', 'C'};%注意A B C矩阵的行数量是相同的 其各代表一列数据 数据类型也可以不同
data = table(A, B, C,'VariableNames', columns); % 基于这些单独的变量创建一个table类型变量data
writetable(data,csvname);
A=[1 2 3;4 5 6]
T = array2table(A)%先转换为table
T.Properties.VariableNames(1:3) = {'x_axis','y_axis','z_axis'}%更具变量数量增加抬头
writetable(T,'file1.csv')
