Matlab小技巧

%使用函数num2str自动标注y轴

x0.11:0.1:100;

yx.^3;

plot(x,y)

str1num2str(min(y));

str2num2str(max(y));

out[Value of y from str1 to str2];

ylabel(out);

%用字符串结构数组进行标注

str1(1){Center each line in the Uicontrol};

str1(2){Also check out the textwrap function};

str2(1){Each cell is a quoted string};

str2(2){You can specify how the string is alighed};

str2(3){You can Use LaTeX symbols like \pi \chi \Xi};

str2(4){\bfOr use bold \rm\itor italic font\rm};

str2(5){\fontname{courier}Or even change fonts};

plot(0:6,sin(0:6))

uicontrol(Style,text,Position,[80 80 250 65],String,str1);

text(5.75,sin(2.5),str2,HorizontalAlignment,right)
