1.4 字符串操作

%%字符串char, 元组cell, 结构(字典)structure   2020.8.26  马玉华

%字符串
a = '12'
b = double(a)   %将字符串中的每一个字符都转换为ASCII码
c = char(49,50)

d = str2num('12')   %字符串转数字。2(two)谐音to
class(d)

e = num2str(12)     %数字转字符串
class(e)
%字符串切片
f = 'abcd'
f(1)
f(1:3)

%元组和结构暂且不讲
%structure2cell, cell2structure

输出结果:

>> A4_char_cell_structure

a =

12


b =

    49    50


c =

1
2


d =

    12


ans =

e =

ans =

char


f =
