MATLAB: How to store output for each input.

input/output

Greetings for the day.
I am an civil enginnering student and new with the world of programing. I tried to load multiple inputs in program and run with for loop and succesfully achived the result for each input.
clc
inputNames = {"mat1.mat", "mat2.mat", "mat3.mat"}
length(inputNames)
for i = [1:length(inputNames)]
    load(inputNames{i})
    i
    fprintf("Lx = Length of shorter span = %d mm \n", Lx)
    fprintf("Ly = Length of longer span = %d mm \n", Ly)
	
endfor
Output:
inputNames =
{
  [1,1] = mat1.mat
  [1,2] = mat2.mat
  [1,3] = mat3.mat
}
ans =  3
i =  1
Lx = Length of shorter span = 6000 mm
Ly = Length of longer span = 7000 mm
i =  2
Lx = Length of shorter span = 7000 mm
Ly = Length of longer span = 8000 mm
i =  3
Lx = Length of shorter span = 8000 mm
Ly = Length of longer span = 9000 mm
Now I want to save the result of each input in different output file.
For example if I run my program with three input files as in above code, i want to store the output in different files i.e, three files.
I really need help to solve this problem.

clc
inputNames = {'mat1.mat', 'mat2.mat', 'mat3.mat'}
length(inputNames)
for i = [1:length(inputNames)]
    load(inputNames{i})
    i
    fileID = fopen(sprintf('file%d.txt',i),'w')
    fprintf(fileID,'Lx = Length of shorter span = %d mm \n', Lx)
    fprintf(fileID,'Ly = Length of longer span = %d mm \n', Ly)
    fclose(fileID);
end
mat1 data will be stored in file1, mat2 in file2 and mat3 in file3.
