How to apply to each sub-set of a vector a different formula?

Suppose I have a vector of order 10000*1. I have to apply different formula for each subset of (100*1). how to do it?

Answer 1

[Azzi Abdelmalek]

A=rand(1,1000) % example
B=reshape(A,100,10)

Then apply your formula to each column of B

Or use a cell array

B=num2cell(reshape(A,100,10),1)

Answer 2

[Matt J]

 A=reshape(A,100,[]);

 for i=1:100

   A(:,i)=func(A(:,i));  %where func() implements the formula

 end
