example1:
str = 'www'
str =
www
>> str2 = 'hello'
str2 =
hello
>> [str,str2]
ans =
wwwhello
example2:
>> str3 = 'welcome'
str3 =
welcome
>> strcat(str,str3)
ans =
wwwwelcome
example3:
strcat({'red','yellow'},{'green','blue'})
ans =
'redgreen' 'yellowblue'
example4:
>> strcat(['red','yellow'],['green','blue'])
ans =
redyellowgreenblue
遇到matlab里面的不懂的方法,第一方法应该是使用 help + 方法名,来看matlab文档。
example:
>> help strcat
strcat - Concatenate strings horizontally
This MATLAB function horizontally concatenates strings s1,...,sN.
s = strcat(s1,...,sN)
