initialize variable in a function

[gigiolone123]

now i give you a stupid example to understand my problem:

Main Program:

global cc;

cc=(1:2:300);

for i=1 to 50

ret=vv();

endfor



function vv

global cc;

cc(g)=g*2; ===> how can i initialize g = 1 ? (only the first time n)
g++;

endfunction


i want to inizialite the variable "g" with 1...
if can't initialize it in a function...i give initialize out it

there is another method? thank

Declare g to be persistent inside function vv(). It will be initialized to 1 and then retain its previous value between successive calls to vv(). Refer to section 7.2 of the manual for more details.

function vv
global cc;
persistent g = 1;
cc(g)=g*2;
g++;
endfunction
