sn20_struct = load('2sn20.mat', 'one1', 'SomeArray');
one1 = sn20_struct.one1;
SomeArray = sn20_struct.SomeArray;
save('2sn20Vectorized.mat', 'one1', 'SomeArray', '-append')
This code does not care what size or datatype one1 or 'SomeArray' are, so you can use similar code for all of your variables. They key point is to load() assigning to a struct, extract the appropriate fields into the variable names you want them to appear in in the other file, and then save() using the -append option.
