一、为方便理解,先定义几个变量
style="margin-left:2.85pt;">a1=5;
a2=[2 3 4 5];
a3=[1:3;10:12];
b1='a';
b2='abcd';
b3=['abcd';'1234';'!@#$'];
b4={ 'abcd';'1234';'!@#$'};
b5='';
b6={ 'abcd','1234','!@#$'};
c1="";
c2="abc";
c3=["abc","123"];
c4={ "abc","123"};
c5=["abc","123";"!@#","xyz"];
c6={ "abc","123";"!@#","xyz"};
