I have that structure
test =
struct with fields:
F0: 243000
I: [3×3 double]
I_1: [3×3 double]
I_X: 5550000
I_XZ: 33000
%[...]
m: 160000
that i want to save 'as it is'
uisave('test')
I save it as name ('test2'), i load it back and i go this
aircraftdata = load('test2.mat')
aircraftdata =
struct with fields:
test: [1×1 struct]
What i want is a structure like this :
aircraftdata =
struct with fields:
F0: 243000
I: [3×3 double]
I_1: [3×3 double]
I_X: 5550000
I_XZ: 33000
%[...]
m: 160000
The whole point is saving the structure untouched and load it with a new name

When you save the struct array, specify the '-struct' option. This will save each of the struct fields separately in the MAT-file. When you call load with an output argument, each of those separate pieces of data from the MAT-file will become fields of the new struct.
S = struct('theAnswer', 42, 'magicMatrix', magic(5), 'nephews', ["Huey", "Dewey", "Louie"])
cd(tempdir)
name = 'temporaryMatfile.mat';
save(name, '-struct', 'S')
whos('-file', name) % Individual variables
data = load(name)
Compare with:
name2 = 'otherTemporaryMatfile.mat';
save(name2, 'S')
whos('-file', name2) % The struct was stored intact
data = load(name2)
data.S

I don't believe uisave offers the '-struct' option. You could try using a different tool, like uiputfile, to select the file to which you want to save. Once you have the file name and path information, use fullfile to construct the fully qualified name and pass name that into save.
