merge fields of two struct in one

[DF]

I have 2 struct variables, let's say s1 and s2, with exactly the same fields:
s1.name: 'alice'
s1.age: 22
s1.height: 175

s2.name: 'alex'
s2.age: 23
s2.height: 180

How can I combine the data in one structure, with the same fields to get something like this:

s3.name: ['alice' 'alex']
s3.age: [22 23]
s3.hieght: [175 180]

The struct variable has many fields and I don't want to do this merge manually field by field.

s1.name='alice';
s1.age=22;
s1.height=175;
s1

s2.name='alex';
s2.age=23;
s2.height=180;
s2

fields = fieldnames(s1)';
fields(2,:) = cellfun(@(f) [s1.(f) s2.(f)], fields, 'unif', false);
smerge = struct(fields{:})

Note that

'>> ['alice' 'alex'] % as *you* require

ans =

alicealex
