Question

在matlab中如何合并矩阵?比如：a=[0.42 0.41 0.67 0.78 0.69 0.32] b=[0.57

Answer 1

a(2,:)=[0,b] %a的第2行放 0,b

a =

0.4200 0.4100 0.6700 0.7800 0.6900 0.3200

0 0.5700 0.2700 0.5500 0.2900 0.3700

>> a(3,:)=0 %第3行置0

a =

0.4200 0.4100 0.6700 0.7800 0.6900 0.3200

0 0.5700 0.2700 0.5500 0.2900 0.3700

0 0 0 0 0 0

>> a(3,3:6)=c %把c放到a的第3行3到6列

a =

0.4200 0.4100 0.6700 0.7800 0.6900 0.3200

0 0.5700 0.2700 0.5500 0.2900 0.3700

0 0 0.3600 0.4800 0.4800 0.3500

希望对你有帮助!
