Can I Load/Combine Vectors Data

I have Multiple .mat Files, contains same set of Vector Array names.

For example, I have file1.mat, and file2.mat but both contains a bunch of arrays with same names, like file1.mat has array1 and file2.mat has array1 as well. However, file1.mat array1 has different data than another array1.

For example, file1.mat 's array1 data is

• 0.01 3
• 0.04 5
• 0.05 6

so the first column has time data, and 2nd column has its own corresponding data following the first column data.

but file2.mat array1 has

• 0.02 19
• 0.03 22
• 0.05 25

Is there any way to load/combine those 2 and make

• 0.01 3
• 0.04 5
• 0.05 6
• 0.07 19
• 0.08 22
• 0.10 25

As you observe, the 2nd file's time column is added on the first file but the data kept same.

number_of_mat_files = 2;
for iLoop=1:number_of_mat_files
    sMatFileName = ['file', num2str(iLoop), '.mat'];%construct mat file name using the file number
    Arr = load(sMatFileName);
    if iLoop==1
        FinalArr = Arr.a;%a is the name of the variable in the mat file
    else
        MaxTime = FinalArr(end,1);
        Arr = load(sMatFileName);
        Arr.a(:,1) = Arr.a(:,1)+MaxTime;
        FinalArr  = [FinalArr ;Arr.a];
    end

end

Hi,assume you are loading file1 with array1 and file2 with array1, try save the following function as combineTwoArray.m and run combineTwoArray('file1.mat','file2.mat') to get the combined array.

function array = combineTwoArray(file_1,file_2)
file1 = load(file_1);
file2 = load(file_2);
array_file2 = [(file2.array1(:,1)+file1.array1(length(file1.array1),1)),file2.array1(:,2)];
array = [file1.array1;array_file2];
end
