s = 'This is the string. The goal is to replace the thes with as';
newstr = regexprep(s, '\<the\>', 'a', 'preservecase');
This matches only words, replacing 'the' with 'a', and when 'The' is matched it replaces with 'A' (conserving case)

Use strrep() to replace space-the-space with space-a-space.
s = strrep(s, ' the ', ' a ');

What? How? What is your string? Look, here is an example that shows it works:
clc;
s = 'This is the string. The goal is to replace the thes with as'
s = strrep(s, ' the ', ' a ') % Replace lower case
s = strrep(s, ' The ', ' a ') % Replace upper case
Result:
s =
This is the string. The goal is to replace the thes with as
s =
This is a string. The goal is to replace a thes with as
s =
This is a string. a goal is to replace a thes with as
It looks like it works to me. What is your string?
