how to write a function called calcrmse that given 2 input vectors checks to see if the vectors are the same size. in matlab

main.m
function rmse = calcrmse(vector1, vector2)

% check if the sizes are equal
if length(vector1) ~= length(vector2)
  error('Input vectors have different sizes!');
end

% calculate the RMSE
squaredError = (vector1 - vector2).^2;
meanSquaredError = mean(squaredError);
rmse = sqrt(meanSquaredError);

end
