将一列附加到矩阵 Matlab

Question

我正在遍历矩阵中的每一列并对该列中的每个元素执行操作。问题是，如何将此列添加到另一个矩阵的末尾？

normalized_features = [];
for col = 1:6;
    cur_col = features(:, col);
    for i = 1:length(cur_col);
        elm = cur_col(i);
        elm = (elm - features_mean(col)) / features_standard_dev(col);
        cur_col(i) = elm;
        if i == length(cur_col)
            % append cur_col to normalized_features matrix
        end
    end
end

Answer 1

您可以像这样附加列：

normalized_features = [normalized_features cur_col];

此操作水平连接两个矩阵。有关详细信息，请参阅 Matrices and Arrays 文档。
