MATLAB: Strrep for more replacing using if

strfindstrrep

s= strrep(origStr, oldSubstr, newSubstr)
          str1==strrep(str,'sport','1');
         str2==strrep(str1,'art','2');
         str3==strrep(str2,'art_u','3'); should be 3  but when print it became  2_u  it's error
what is the error ? and how to use if condition with strrep to specify any word for replacing?? if u have more replacing ? art=2 , and when 'art_u' it's one word it will be 2_u it is error the output art=2 so to be art_u= 2_u is wrong should be 3 only how to solve ???

Best Answer

Remove the semi-colons and see what happens ...
str = 'hello sport art art_u' ; % example string
str1 = strrep(str,'sport','1')
str2 = strrep(str1,'art','2') % not what you want
str3 = strrep(str2,'art_u','3')
You can switch the last two statements:
    str2 = strrep(str1,'art_u','3') 
    str3 = strrep(str2,'art','2')
NB You most likely want to assign (A = B) and not compare (A == B)
