Hi,
Is there possible to add more than one element to an array at the same time?Like in this array:
x=[];
x=[x,3];%and I want to add a number of 100 3 in x

You mean x = [x,[100,3]];
?

@TorstenNo, I want to add 3 to x 100 times. Sorry for bad explanation.

x = [x,3*ones(1,100)];

Yes it's OK, horizontal concatenation
x=[x,3]
Example:
>> x=1:4
x =
1 2 3 4
>> x=[x,9:12]
x =
1 2 3 4 9 10 11 12

@KALYAN ACHARJYAOk, but if I want to add 3 digit 100 times in x how could I try?

See the repmat (Copiese array n times horizantly)
x= repmat(x , [1,n]) ;
e.g.
x =
1 2 3
>> x=repmat(x,[1,3])
x =
1 2 3 1 2 3 1 2 3
If this is not looking for then, please see the @Torsten comment
