Hey i could use a small help with the For loop

for i=1:10

x=input('X wert Point=');

y=input('Y Wert Point=');

K = [x;y];

end

so this is my code and i want to get as answer K1 = [x1;y1] , k2=[x2;y2] ..... etc

it only saves the last 2 numbers i put as K=[a;b],what do i need to change?.

Thank you in advance

Subscript ‘K’:

for i=1:10
    x=input('X wert Knote=');
    y=input('Y Wert Knote=');
    K(:,i) = [x;y];
end

That should do what you want.

Oh so i have to save them as a matrix i cant make an index i suppose.

Well thank you very much for the help.

My pleasure.

I do not understand your comment. If you want to save them, you can save them as a matrix as I did here, or you can save them as a cell array:

for i=1:10
    x=input('X wert Knote=');
    y=input('Y Wert Knote=');
    K{i} = [x;y];
end

Here, the first element of the cell array is addressed as ‘K{1}’, the second as ‘K{2}’, and so for the rest.

Saving them as dynamically-created, numbered variables such as ‘K1’, ‘K2’ and so forth is considered very bad programming practice. That creates complicated code that is prone to crashing and difficult to debug because of its complexity. Avoid it at all costs!
