MATLAB: How to create a matrix composed of some data in another matrix

Hello,

I am new in Matlab and I would like to know if it is possible to create a matrix composed of some data in another matrix?

I would like to collect in this new matrix data with a first data being in the cell located on line 5 then the following data is 4 lines below the first data (n + 4) and the third data is also 4 lines below the second data etc.

"...in this new matrix data with a first data being in the cell located on line 5 then the following data is 4 lines below the first data..."

B=A(5:4:end);

Read the "Getting Started" documentation and examples on addressing modes -- the time spent will be more than amply paid back in getting started (so to speak :) ) more quickly.
