Details:

I explain my problem in examples:
If I define m variable once

m=2;
m
function y=f(Pi)
        global m;
        m
        m=m+Pi;
        y=m;
end
y=f(5)
m

I get an answer:
 source ("test4.m")
>>>m =  2
m =  2
y =  7
m =  7

If I define the variable m twice or more:

m=2;
m=3;
m
function y=f(Pi)
        global m;
        m
        m=m+Pi;
        y=m;
end
y=f(5)
m

I get bug:

>>>m =  3
m = [](0x0)
y = [](0x0)
m =  3
