英语翻译
bb=[………………]';

flow=[………………]';
X = [ones(size(load)) flow load.*flow load.*load.*load ];
b = regress(bb,X);
scatter3(load,flow,bb,'filled');
hold on

flowfit = min(flow):.1:max(flow);
[loadFIT,flowFIT] = meshgrid(loadfit,flowfit);

前三行是输入数据,帮我把后面的代码翻译下,告诉我每句话是什么指令?
英语翻译bb=[………………]';load=[………………]';flow=[………………]';X = [ones(size(load)) flow load.*flow load.*load.*load ];b = regress(bb,X);scatter3(load,flow,bb,'filled');hold onloadfit = min(load):500:max(load);flowfit = m
X = [ones(size(load)) flow load.*flow load.*load.*load ];
%建立一个向量,包含和load数据一样维度的元素全为1的数组,flow数组,load.*flow数组 和 load点乘的3次方
b = regress(bb,X);
%对X进行回归
scatter3(load,flow,bb,'filled');
%画图,画出load,flow,bb的散点,并且数据点颜色填充
hold on
%表示下个图和上面的散点图画在一起
loadfit = min(load):500:max(load);
flowfit = min(flow):.1:max(flow);
%建立两个数组格式最小值：公差（步长）：最大值
[loadFIT,flowFIT] = meshgrid(loadfit,flowfit);
%数据网格化
YFIT = b(1) + b(2)*flowFIT + b(3)*loadFIT.*flowFIT+b(4)*loadFIT*loadFIT*loadFIT ;
%计算目标函数值
mesh(loadFIT,flowFIT,YFIT);
%网格法做三维图
view(50,10)
%设定视角
