change a vector of a matrix

Hi, I have a function

function survival(Si) where Si is a matrix (mx8)

Inside the function I create a vector 'status (mx1)', at the end I want to change one of the columns of the matrix Si by 'status'. The idea is that the matrix that the function use as 'entry' change, for use it in the next step. thanks

[Walter Roberson]

function Si = survival(Si)
  ...
  status = [...];
  column_to_change = ...;  %e.g., 7
  Si(:,column_to_change) = status;
end

use the matrix as an output argument too:

function Si = survival(Si)
%your code here, you can change your Si matrix too
