How to combine 2 structures into 1?

>> a = struct('a1',1,'a2',2,'a3',3)

a =

struct with fields:

a1: 1

a2: 2

a3: 3

>> b=struct('b1',11,'b2',12,'b3',13,'b4',14)

b =

struct with fields:

b1: 11

b2: 12

b3: 13

b4: 14

Want to combine structures a and b into c like:

>> c = struct('a1',1,'a2',2,'a3',3,'b1',11,'b2',12,'b3',13,'b4',14)

c =

struct with fields:

a1: 1

a2: 2

a3: 3

b1: 11

b2: 12

b3: 13

b4: 14

d=[struct2cell(a);struct2cell(b)];
f=[fieldnames(a);fieldnames(b)];
c=cell2struct(d,f)
