From the description, I understand there is a file named 'Aleator.xlsx' that contains the necessary data. You want to use this data to solve a system of linear equations.
We can use the “readmatrix” function to load the data, and the "\" operator to solve the system of linear equations.
Here I have attached sample code for better understanding.
% Step 1: Load the Excel file
filePath = 'Aleator.xlsx'; % Replace with your actual file path
data = readmatrix(filePath);
% Step 2: Extract the integer values from column D
D = data(:, 4); % Assuming column D is the 4th column
% Step 3: Construct the difference matrix DM
DM = zeros(10, 10);
for i = 1:10
DM(i, :) = D(i) - D(i+1:i+10);
end
% Step 4: Extract b1 to b10
b = [D(1027); D(1026); D(1025); D(1024); D(1023); D(1022); D(1021); D(1020); D(1019); D(1018)];
% Step 5: Solve the system of equations
% DM' * a = b
a = DM' \ b; % Transpose DM to match the equation format
% Step 6: Write the result in Vector Rez
Rez = a;
% Display the result
disp('Vector Rez =');
disp(Rez);
