hi everyone hope you can help me i know this request is very simple but i am new. I want to generate a sequence of numbers from 5 to 15 and remove numbers 9 and 13 using for and while . loops Thank you everyone

This sounds like a homework assignment because of your insistence on using for and/or while loops. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.
If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.
If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

Hello,
Not sure why you would like to do this using a loop, but anyways:
l=5:15; % Array containing the values from 5 to 15
% you can always delete the elements doing l(5)=[];
i=1;
while i<length(l);
if l(i)==9;
l(i)=[];
elseif l(i)==13;
l(i)=[];
end
i=i+1;
end
ll=5:15; % Array containing the values from 5 to 15
lll=zeros(size(ll,2)-2,1); % Array where your result will be stored
j=1;
for i=1:length(ll)
if ll(i)==9 || ll(i)==13
continue
else
lll(j)=ll(i);
j=j+1;
end
end

No need for loops.
A=randi([5,15],1,100);
A(A==9|A==13)=[];
A
A = 1×83
12 5 7 15 12 6 8 8 10 15 6 12 8 8 6 8 11 6 8 15 6 14 11 10 7 11 6 8 7 12

if it is required to use for and while to generate a sequence of numbers in the order from 5 to 15 and excluding 9 and 13, how to do it?
