如何用matlab对两组数对应的数进行大小比较 用大数减去小数输出结果
第一组数：38 38 28 28 28 18 18 18 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 20 20 20 20 20 20
第二组数：29.1900 37.2800 59.4000 58.0500 53.0300 33.5100 7.9700 36.6600 25.1200 21.8300 35.5200 19.9000 2.0600 20.6300 6.1500 24.6500 15.1700 4.6600 2.0400 2.2800 4.0800 3.5400 32.6800 34.9800 24.7800 14.7000 2.7000 26.9900 3.3100 19.3600
% 增减发电量的计算
% j1,j2 计划出力
% s1,s2 实际出力
% delt 实际间隔
j1=xlsread('ghy200902.xls','2.1','b3:b289')'
j2=xlsread('ghy200902.xls','2.1','b4:b290')'
s1=xlsread('ghy200902.xls','2.1','g3:g289')'
s2=xlsread('ghy200902.xls','2.1','g4:g290')'
delt=1/12;
zjdl=0; % 增发电量
jsdl=0; % 减发电量
if s1>=j1;
if s2>=j2;
% 1) s1>=j1 & s2>=j2
zjdl=((s1-j1)+(s2-j2))*delt/2;
jsdl=0;
else
% 2) s1>=j1 & s2=j2;
% 3) s1=j2
ks=(s2-s1)/delt;
kj=(j2-j1)/delt;
x=(j1-s1)/(ks-kj);
y=ks*x+s1;
zjdl=(s2-j2)*0.5*(delt-x);
jsdl=(j1-s1)*0.5*x;
else
% 4) s1

你的第一数组50个,第二组数30个,我将第一组的后面20个去掉了.
假设excel文件为d:\book1.xls,第一数组存于sheet1 的第1行,第二数组存于第2行.matlab程序很简单：
data=xlsread('d:\book1','sheet1') %读入数据,data为2行20列数组
data_compare=data(1,:)>data(2,:) %比较两组数据大小
data_sub=abs(data(1,:)-data(2,:)) %减法 大数减小数就是求绝对值
执行结果：
