Matlab - content filtering using strings

Question

k = strcmp(word{w},com_word{y});
if(k) new_word = strrep(word,word{w},'');

Say i wanna do something like this , comparing two strings word by word for example:

str1 : ' my world is awesome '

str2 : ' my world was awesome '

Now i want to compare the words in str1 with those in str2 and remove the common words in both. Finally, only ' is ' remains in str1.

It would really help us if you posted what you've tried and detail what, exactly, isn't working. Welcome to SO! — darthbith

Tools that you can use here - regexp, strtrim, setdiff.

Code

str1 = ' my world is awesome '
str2 = ' my world was awesome '

split1 = regexp(strtrim(str1),'\s','Split')
split2 = regexp(strtrim(str2),'\s','Split')

str1_exclusive = setdiff(split1,split2)
str2_exclusive = setdiff(split2,split1)

Output

str1_exclusive = 
    'is'
str2_exclusive = 
    'was'

yeah , thanks ! but the str1_exclusive and str2_exclusive are in the cells' format, what if we want them to be just strings ? as that what we read from a text file ?

@PriyamSoneji Use char().

sorry to be asking such questions , i'm doing it for the first time, but it gives it in a columnar format only , while displaying , can't it be in a row format ? like our initial strings are ?

@PriyamSoneji That's okay! We learn things as we try them out!

How do we get it to come as an actual string ? As our initial strings were ?
