Creating a tensor from multiple matrices

I have four matrices I am trying to combine into a tensor. I.e I want to turn four matrices of 155 x 275 into 155x275x4 and cumulatively add them together. This is what I have so far, please can someone help me? Thanks Charity

%% IMPORTING THE MATRICES

U1= importdata ('U1.txt');

U2= importdata ('U2.txt');

U3= importdata ('U3.txt');

U4= importdata ('U4.txt');

%% CREATING A TENSOR

n=4;

tensor1= zeros (155,275,n); %setting matrix size

%% CUMULATING VALUES

for i=1:n

tensor1(:,:,i)= what should go here??

end

CumulativeU=cumsum(tensor1,3);

You can use the “cat” function to create a tensor.

cat(3,U1,U2,U3,U4);
