哥哥的2007年的发动机数据,07年搞过的,他丢了,我有回顾了一下子
1. 装上excel link 在excel的 工具 加载宏 选择 matlab toolbox 下的exlink 文件夹中的excllink.xla,便可使用excel link了
2. 数学插值的方法就不说了,help中说的很清楚,用的是 griddata(X,Y,F,Xa,Ya, 'cubic')
3.在矩阵中找数据的方法,在矩阵中先加上行与列的标号,使用hlookup和vlookup,找倒行列的地址,再用index函数找到数据。
4.最后就是对原始试验数据进行统计,圆整后再列出一个二维表

然后再将数据放到相应的位置中去,其中利用到下面的程序和上一篇的读写数据的方法。
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
a=zeros(21,18);
count=0;
x=0;
y=-500;
for i=1:21
for j=1:18
for m=1:2795
if (rpm(m)==x & nm(m)==y)
count=count+1;
end
end
a(i,j)=count;
count=0;
y=y+100;
end
y=-500;
x=x+100;
end
