suppose i have the vector having 50 values values, no i want to split that values in the group of five?
group 1=(first five values)
group 2=(next five values)
.
.
.
The vector i have is
0.6137
0.8946
1.1238
1.5200

Assuming your vector is divisible by 5, you could do this:
v = your vector
g = reshape(v,5,[]); % reshape v into a 5 x N matrix
Then your groups of 5 would be g(:,1), g(:,2), g(:,3), ... etc.
You DO NOT want to have variables named group1, group2, etc. because that is very hard to manage downstream in your code, forcing you to use eval( ) to process them in a loop, etc. For a full discussion of why this is discouraged:
