problem to save structura in .mat file

a.w=1;

a.r="ff";

a.v=3;

a.s="a.tst";

save(a.s,'-struct','a')

a=load("a.tst","-mat");

i see 1X1 struct and not as original

Hello Luca, your question seems little unclear. Since you are saving it as a struct and thus it is being returned as a struct. If you want to access different properties of it you can access them by '.' dot operator.

I had an analog example and was unable to change the fields

Now problem is solved .thanks

"i see 1X1 struct and not as original"

The original is also a 1x1 struct. They look exactly the same to me:

a.w = 1;
a.r = "ff";
a.v = 3;
a.s = "a.tst"

a = struct with fields:
    w: 1
    r: "ff"
    v: 3
    s: "a.tst"

save(a.s,'-struct','a')
clearvars
b = load("a.tst","-mat")

b = struct with fields:
    w: 1
    r: "ff"
    v: 3
    s: "a.tst"
