reads in n numbers from the user,storing the numbers in a vector, then print the numbers from the ends inwards(la​st,first,s​econd last,second)

% question demo

% How many numbers will you enter? : 5

% Enter a number: 3

% Enter a number: 5

% Enter a number: 6

% Enter a number: 4

% Enter a number: 3

% Your numbers from outside to middle are : 3 3 4 5 6

% I have no ideo how to do that

I'm not a lawyer, but this doesn't look to me like it rises to the level of creatitivity that is required for copyright. This is an algorithm description with a tiny example. While copying an answer without attribution likely constitutes some for of academic fraud, I don't see how you would have grounds to have this deleted.

It is of course possible the OP agreed to some condition as part of the course to not share the question. In that case, you have a case against the OP.

try this:

numbers = input('How many numbers will you enter: ');
% create a empty vector to store the numbers
n = [];
Opsetnumber=cell(length(numbers),1);
% use nested loop 
for i = 1:numbers
    Numbers = input('Please enter a number: ');
    n= [n,Numbers]; % let variable n to store the entered number from users
    Opsetnumber = [];
    for j = n:-1:1
        Opsetnumber{i} = n;        
    end
end
output=sort([Opsetnumber{:}])';
% fprintf('Your numbers form outside to middle are: %d\n',output);
vec = ['Your numbers form outside to middle are: [', repmat('%g, ', 1, numel(output)-1), '%g]\n'];
fprintf(vec, output)

[Arif Hoq]

for the output of 3 3 4 5 6 ( without comma)

vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(output)-1), '%g \n'];
fprintf(vec, output)

[Shuoze Xu]

It doesn't work.

% That is my result

How many numbers will you enter: 3

Please enter a number: 1

Please enter a number: 2

Please enter a number: 3

Your numbers form outside to middle are: 1 2 3

[Shuoze Xu]

Could we use the single loop to did it.

I mean that I do not use the nested loop.

[Arif Hoq]

try this:

numbers = input('How many numbers will you enter: ');
n = [];
Opsetnumber=cell(length(numbers),1);
for i = 1:numbers
Numbers = input('Please enter a number: ');
n= [n,Numbers]; % let variable n to store the entered number from users
Opsetnumber{i} = n(i);        
end
output=sort([Opsetnumber{:}])';
vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(output)-1), '%g \n'];
fprintf(vec, output)

[Shuoze Xu]

It seem doesn't work.....

While, thank you, i may ask my professor on Monday.

[Arif Hoq]

it should work..see my result

[Arif Hoq]

if you put the number in a scaler form , see it's working

% numbers = input('How many numbers will you enter: ');
numbers=6;
n = [];
Opsetnumber=cell(length(numbers),1);
for i = 1:numbers
% Numbers = input('Please enter a number: ');
Numbers=[1 2 3 7 5 6];
n= [n,Numbers]; % let variable n to store the entered number from users
Opsetnumber{i} = n(i);        
end
output=sort([Opsetnumber{:}])';
vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(output)-1), '%g \n'];
fprintf(vec, output)

Your numbers form outside to middle are: 1 2 3 5 6 7 

[Shuoze Xu]

While....bro, my question is how to print the results from end inwards

% demo

%How many numbers will you enter? : 5

% Enter a number: 1

% Enter a number: 5

% Enter a number: 6

% Enter a number: 4

% Enter a number: 3

% Your numbers from outside to middle are : 3 1 4 5 6

[Arif Hoq]

check it:

% numbers = input('How many numbers will you enter: ');
numbers=5;
n = [];
Opsetnumber=cell(length(numbers),1);
% use nested loop 
for i = 1:numbers
% Numbers = input('Please enter a number: ');
Numbers=[3 5 6 4 3];
n= [n,Numbers]; % let variable n to store the entered number from users
Opsetnumber{i} = n(i);        
end
output=[Opsetnumber{:}]';
out2=output([end 1 end-1 2 3],:)

out2 = 5×1

3 3 4 5 6

% fprintf('Your numbers form outside to middle are: %d\n',output);
vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(out2)-1), '%g \n'];
fprintf(vec, out2)

Your numbers form outside to middle are: 3 3 4 5 6 

[Arif Hoq]

using input prompt:

numbers = input('How many numbers will you enter: ');
% numbers=5;
n = [];
Opsetnumber=cell(length(numbers),1);
% use nested loop 
for i = 1:numbers
Numbers = input('Please enter a number: ');
% Numbers=[3 5 6 4 3];
n= [n,Numbers]; % let variable n to store the entered number from users
Opsetnumber{i} = n(i);        
end
output=[Opsetnumber{:}]';
out2=output([end 1 end-1 2 3],:)
% fprintf('Your numbers form outside to middle are: %d\n',output);
vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(out2)-1), '%g \n'];
fprintf(vec, out2)

[Shuoze Xu]

it displays five numbers but i just enter 3

[Arif Hoq]

try this: I have edited here

out2=output([end 1 end-1 2:end-2],:)

% numbers = input('How many numbers will you enter: ');
numbers=3;
n = [];
Opsetnumber=cell(length(numbers),1);
% use nested loop 
for i = 1:numbers
% Numbers = input('Please enter a number: ');
Numbers=[1 2 3];
n= [n,Numbers]; % let variable n to store the entered number from users
Opsetnumber{i} = n(i);        
end
output=[Opsetnumber{:}]';
out2=output([end 1 end-1 2:end-2],:)

out2 = 3×1

3 1 2

% fprintf('Your numbers form outside to middle are: %d\n',output);
vec = ['Your numbers form outside to middle are: ', repmat('%g ', 1, numel(out2)-1), '%g \n'];
fprintf(vec, out2)

Your numbers form outside to middle are: 3 1 2 

[Shuoze Xu]

Wow, it works.

Thank you so much

[Arif Hoq]

my pleasure

Why are you dynamically growing the array? And why the cell array? Also, your order is hard-coding the number of elements.
