write a function file, (2, err] = functioncalculation (x, y), which takes inputs z and y as two vectors ofarbitary lengths and calculates the following hunction. in matlab

main.m
function [result, err] = functioncalculation(x, y)
    % Check if vectors have the same length
    if length(x) ~= length(y)
        error('Vectors must have the same length');
    end

    % Perform calculation
    result = sum(x .* y) / sum(y);
    
    % Set error to 0
    err = 0;
end
