I don't want to repeat these , I want to use a loop for it

I don't want to repeat these all time , I want to use a loop for it instead of copy and paste it all time ?

Can I just use a ( for ) for it ??????

KG1=zeros (28,28);
KG2=zeros (28,28);
KG3=zeros (28,28);
KG4=zeros (28,28);
KG5=zeros (28,28);
KG6=zeros (28,28);
KG7=zeros (28,28);
KG8=zeros (28,28);
KG9=zeros (28,28);
KG10=zeros (28,28);

Numbering variables is a sign that you are doing something wrong.

Copy-and-pasting code is a sign that you are doing something wrong.

You can easily avoid both of these issues by using indexing. Indexing is simple, neat, easy to debug, and very efficient (unlike what you are trying to do).

perhaps instead of defining 10 variables or dynamically creating them in a for loop, you can store each matrix of zeros as a cell array.

KG = {zeros(28,28)};
KG = repmat(KG,10,1);

% now you can call out each cell array like so:
KG{1};
KG{2};
KG{3};
%etc...

Thanks bro for your answering I just found the answer in another way.

it was

for i=1:10
        eval(['KG' num2str(i) '= zeros (28,28)']);
end
