Merging 2 mat files

I have 2 mat files each having 4 variables lets say a,b,c and d.

mat file 1 variables:

variable a size 14 X 25

variable b size 14 X 1000

variable c size 14 X1

variable d size 14 X 4

mat file 2 variables:

variable a size 36 X 25

variable b size 36 X 1000

variable c size 36 X1

variable d size 36 X 4

I need a single mat file with variable sizes as

variable a size 50 X 25

variable b size 50 X 1000

variable c size 50 X1

variable d size 50 X 4

Can anyone help me with this one?

clear

x1 = load('mat_file_1.mat');
x2 = load('mat_file_2.mat');

a = [x1.a;x2.a];
b = [x1.b;x2.b];
c = [x1.c;x2.c];
d = [x1.d;x2.d];
