Divide a vector size into indivisible numbers

I have a vector with size of 773 in length.

Just want to make an average for every 10 elements, I use following code:

Avg=mean(reshape(A,10,[]))

but I get an error: not divisible into total number of elements, 773.

How can I fix that?

[Thorsten]

 Avg=mean(reshape(A(1:770),10,[]))

or more general

Avg=mean(reshape(A(1:floor(numel(A)/10)*10),10,[]))

Thank you for your help. both give me this error: Index exceeds matrix dimensions.

A bracket was missing in your code

thanks alot

There was a parenthesis missing, I corrected it above. It should work now.
