Average of 3 one dimensional matrix loaded by .mat file

I have 3 one dimensional matrix as .mat file.

RF1=[1 3 4 9] %RF1.mat

RF1=[1 9 2 1] %RF1.mat

RF1=[1 2 4 7] %RF1.mat

I need avg Matrix RF=[(1+1+1)/3 (3+9+2)/3 (4+2+4)/3 (9+1+7)/3]

Code:

I have loaded them like

RF1=load("RF1.mat");

RF2=load("RF2.mat");

RF3=load("RF3.mat");

But, the problem is, after loading this way, I cannot make an average matrix. When I am inputting

RF=(RF1+RF2+RF3)/3

Command windows is showing like this-

Operator '+' is not supported for operands of type 'struct'.

How can I import properly and get the average matrix?

%The following will return the structure
RF1=load("RF1.mat");
RF2=load("RF2.mat");
RF3=load("RF3.mat");
% You need to extract the data
RF1 = RF1.RF1;
RF2 = RF2.RF2;
RF3 = RF3.RF3;

% Or you can replace above by:
load("RF1.mat", "RF1");
load("RF2.mat", "RF2");
load("RF3.mat", "RF3");

Thanks a lot

"% Or you can replace above by"... but loading into an output is strongly recommended.
