With simulated 'actual' and 'measured' data:

x_actual_values = sin(linspace(0,pi,1000));
x_measured_values = x_actual_values + 0.01*randn(size(x_actual_values));
error_in_measurement = x_measured_values - x_actual_values;
mean_error = mean(error_in_measurement)
mean_absolute_error = mean(abs(error_in_measurement))
std_error = std(error_in_measurement)
