Combine mat files into one, then combine all variables into one

Hello. I have multiple MAT files all containing the same variables with the same name but different lengths. What I'd like to do is combine all the mat files so that my variables will have the data from all the mat files.

So if I have from mat file one

variable 1=[ 1, 2, 3]

variable 2=[1, 2, 3]

and from mat file 2

variable 1= [4, 5, 6, 7]

variable 2 = [4, 5, 6, 7]

They will combine so that I have mat file 3

variable 1 = [1, 2, 3, 4, 5, 6, 7]

variable 2 = [1, 2, 3, 4, 5, 6, 7]

below is an image showing the mat files and some of the variables.

I actually ended up using hte following script which worked for me:

data1 = load("2022_07_28_12_37_19_2022_08_01_17_36_27.mat");

data2 = load("2022_07_28_12_37_19_2022_08_01_17_38_41.mat");

Time = vertcat(data1.variable1, data2.variable1);

filename = ["abc001.mat" "def002.mat"];     % list of the files in order
variable1all = [];
variable2all = [];

for i=1:length(filename)
    load(filename(i));
    variable1all = [variable1all variable1];
    variable2all = [variable2all variable2];
end
