For loop to save doubles in .mat files

I have a .mat file which stores the variables:
E.g: name: ABC, type : 20 x 1; class: double
name: DEF, type : 20 x 1; class: double
name: GHI, type : 20 x 1; class: double
name: JKL, type: 1 x 1; class: struct
name: JKL, type: 1 x 1; class: struct
name: XYZ, type: 7 x 1; class: cell
name: LMN, type : 30 x 1; class: double
etc.
I would like to use only the (20 X1) doubles one by one in another line of code. For instance,
load_mat = load('some_mat_file.mat')
new_var = load_mat.DEF;
new_var = load_mat.GHI;
But instead of writing repeatedly, could you provide an example of a for loop or something else? Thanks a lot in advance.

load_mat = load('some_mat_file.mat')
% create a new structure, "new_mat", which contains
% only the 20x1 doubles from load_mat:
new_mat = struct();
f = fieldnames(load_mat);
for ii = 1:numel(f)
if isa(load_mat.(f{ii}),'double') && isequal(size(load_mat.(f{ii})),[20 1])
new_mat.(f{ii}) = load_mat.(f{ii});
end
end
new_mat
