You can pass k to the function as a global variable. You need to declare
it as such in the main workspace and within the function:

all_a = ones(1, 20);
global k;
for k = 1:20
~  function y = f(t)
~    global k;
~    x = mod(t, pi);
~    s = t*(pi-t);
~    y = s*cos(k*t);
~  endfunction
~  a = (2/pi) * quad('f', 0, pi);
~  all_a(k) = a
endfor

'help -i global' should give you more information.
