MATLAB: Deleting part of chars

charrandom

So I have a char like 'FSAJFALSFJSCXKHZVUIAHFKFSDVXCNMVBMAEHFSADFDSASADFHDSUIVCX'
and i need to delete one random length of char longer than 10 that's outside of first 10 and last 10. i have to repeat this 10 times so i have 10 char that has random length deleted as long as it's within the limited range (outside first 10 and last 10).
for example, if my char has 100 characters, it might delete 11~60 or 43~54 or 50~68. but not 9~44 or 77~95 because these are within first 10 or last 10. how can i accomplish this?

% Random string with 100 A-Z characters
str = char(randi([65 90],1,100));
% Start position (random number between 11 and 80)
pt1 = randi([11 80],1);
% End position (random number between pt1+9 and 89)
pt2 = randi([pt1+9 89],1);
% Delete characters between pt1 and pt2
str(pt1:pt2) = [];
