要将代码改成只有一行或一列的三维柱状图，你可以使用`meshgrid`函数生成对应的X和Y坐标，并将Z转置成一行或一列。下面是修改后的代码：

clc;clear;
%确定图片的位置和大小，[x y width height]
figure('position',[150,100,750,650]);
%准备数据
Z = [70,75,80,85; 70,75,80,85; 70,75,80,85; 70,75,80,85];
%设置柱子颜色,颜色为RGB三原色，每个值在0~1之间即可
color_matrix = [100,255,150; 50,152,65; 129,211,176; 108,99,117]/255;

%生成X和Y坐标
[x, y] = meshgrid(1:size(Z,2), 1:size(Z,1));

%转置Z成一行或一列
Z = Z(:)';

%画柱状图
h = bar3(x, y, Z);
axis([-inf inf -inf inf 60 100])
for n = 1:numel(h)
    cdata = get(h(n), 'zdata');
    set(h(n), 'cdata', cdata, 'facecolor', color_matrix(n,:));
end

%设置小标签
set(gca,'yticklabel', {'A1','A2','A3','A4'}, 'Fontname', 'Times New Roman', 'FontSize', 11);
set(gca,'xticklabel', {'M_1','M_2','M_3','M_4'}, 'Fontname', 'Times New Roman', 'FontSize', 11);

%修改每个轴的标签
ylabel('标签Y', 'Fontname', '宋体', 'FontSize', 14);
xlabel('标签X', 'Fontname', '宋体', 'FontSize', 14);
zlabel('标签Z', 'Fontname', '宋体', 'FontSize', 14);
legend({'M_1','M_2','M_3','M_4'});

这样修改后的代码将会生成只有一行或一列的三维柱状图。
