MATLAB: Adding charecters to a string

Question

How can I add a charecter or an element into a string.

for exaple I have the word 'sTudent' I need to add the letter B after each letter in the word

wich means I should have a an aswer 'sBTBuBdBeBnBt'

a string is just a word without spaces.

it has to be added but not after the last letter in the word as it shown in the example.

please help me!

Answer 1

T = regexprep('sTudent', '.', '$&B')

or

 T = 'sTudent';
 T(2,:) = 'B';
 T = reshape(T, 1, []);
