matlab大括号妙用
其实在matlab中大括号用的也不是很多，反而单引号和中括号用的相对多些，我所看到的主要有下面这些情况：
1.在定义几个变量或字符串时如：
1.student=struct（'name',{'Annie'},'scores',{70,89,100,45}）定义构架函数
2.A={[1,4,3;0,5,8;7,2,9]}%定义元胞数组
3.prompt={'Entermatrixsize:
','Entercolormapname:
'};
title='Inputforpeaksfunction';
lines=1;
def={'20','hsv'};
answer=inputdlg（prompt,title,lines,def）;%定义输入信息对话框
2.定义某一图形或其他对象属性时:
（％统计图形，分位点）
clf;
v=4;
p=0.95;
q=chi2inv（p,v）;
x=0:
0.1:
15;
kf_4=chi2pdf（x,v）;
plot（x,kf_4,'b'）,holdon
xxf=0:
0.1:
q;
yyf=chi2pdf（xxf,v）;
fill（[xxf,q],[yyf,0],'g'）
text（q*1.01,0.01,num2str（q））
text（10,0.16,['fontsize{16}x~{chi}^2''
（4）']）
text（1.5,0.08,'fontname{隶书}fontsize{22}置信水平0.95'）
text（12,0.008,'downarrow','fontsize',22）
text（11,0.03,'fontname{隶书}fontsize{22}拒绝域'）
再看下面的程序
fork=1:
12
L{k}=membrane（k）;
End
输出：
L{1}
