Save and load structure array MATLAB

Question

I am trying to save and load structure arrays in a MAT-file, but the structure array keeps changing every time I reload it. If save the following and reload it, it keeps adding struct in front.

struct.field1
struct.field2

save data.mat struct

struct = load('data.mat');

I know that this is happening because I load the file in a variable which makes it a struct and that it won't if I use only:

load('data.mat')

However I am calling the load command within a function and therefore I cannot use this. Does anyone have an idea how to solve this, so that I don't get:

struct.struct.struct.struct.struct.field1;
struct.struct.struct.struct.struct.field2;

after couple of times reloading the data.mat file, but just this:

struct.field1;
struct.field2;

Kind regards,

To avoid adding deeper nested structs you could choose to save all fields as individual variables using the content option -struct

MystructName.field1 = 0
MystructName.field2 = 1

save('data.mat', '-struct', 'MystructName')

Then load the data to a variable and I'll see that the structure hasn't changed

MyStructName = load('data.mat')
MyStructName = 
    field1: 0
    field2: 1

Ps. Perhaps this is only in your example, but naming your struct to struct is bad since it overwrites the Matlab built-in function named struct.
