"i want to save decimal ii value in arrays eg JJ[1]=1,jj[2]=1.1,JJ[3]=1.2 ...etc"

What's wrong with this ?

JJ=1:0.1:10;

You can do this without a counter variable if you use the helper function Enumerate.

for i=Enumerate(1:0.1:10)
   a(i.Index)=i.Value;
end

function [ output ] = Enumerate( items )
   output = struct('Index',num2cell(1:length(items)),'Value',num2cell(items));
end

for indexing you need to introduce another variable, like

jj = 1;
for ii=1:0.1:10
       a(jj)=ii
       jj = jj+1;
end

or

for ii=1:1:10/0.1
       a(ii)=ii*0.1;
end

also have a look at the sub2ind function if you just want to store the counter in a vector.

another alternative. I don't know what your loop is doing, but at what I'm guessing I would do it as follows:

A = 1:0.1:10;
for ii=1:1:length(A)
       do something;
end
