Global variable in octave

Question

global m = 1;
function p = h()
  m
end
h()

I am trying to run this script, but I am getting this error:

'm' is undefined next to column 4 of column

Please tell me how can I use a variable from functions?

You have to declare var also global inside the function as described here: https://www.gnu.org/software/octave/doc/interpreter/Global-Variables.html

global m = 1;
function p = h()
  global m;
  m
endfunction
h()
