Inserting a tab character into a string

I am attempting to insert a space into a string. Here is my code:
t1 = 'Control Chart For ';
t2 = '\t';
t3 = num2str(w);
t4 = ' water flow ';
t5 = '\t';
t6 = num2str(o);
t7 = ' oil flow ';
str = strcat(t1, t2, t3, t4, t5, t6, t7);
This should yield:
Control Chart For 5 water flow 3 oil flow
however it yields instead:
Control Chart For\t5 water flow\t3 oil flow
Just adding spaces in the string does not work either and making the string \t instead of '\t' also fails.

A nicer way of doing it is
str = sprintf('Control Chart For \t %d water flow \t %d oil flow',w,o)

I would go for this approach, it is more readable the way space chars are handled.

char(9) instead of only one string doesn't seem to work, I also tried, sprintf('\t'), this way works:
t1 = 'Control Chart For ';
t3 = [char(9) num2str(w)];
t4 = ' water flow ';
t6 = [char(9) num2str(o)];
t7 = ' oil flow ';
str = strcat(t1,t3, t4, t6, t7)

Are you trying to insert a tab character, or just white space? If the latter, you can concatenate with square brackets:
>> str = [t1, t3, t4, t6, t7]
Then the trailing whitespace in t1, etc, will not be dropped, and you don't need to manually insert the space.
Looks like this syntax works for tab as well:
>> str = [t1, char(9), t2, t3, t4, t5, t6, t7]

This will work:
str = sprintf([t1, t2, t3, t4, t5, t6, t7])

You can also use the tab itself, but you need to disable the "insert white spaces" option at the editor preferences. Another way of doing that would be by copy pasting the tab character from another editor.
