Plotting line of regression analysis

Hi, I'm trying to plot a line for my regression analysis on my scatter graph. I have calculated the regression using a function 'linear_regression' and it has given me the R2, slope and RMSE values as seen in the picture. How can I plot this line?

LR1=linear_regression (new_exp_wear_data,new_caliberated_pred_data );

figure(200);

scatter (new_exp_wear_data,new_caliberated_pred_data)

xlabel('experimental')

ylabel('predicted')

Just add lsline after scatter ...

LR1=linear_regression (new_exp_wear_data,new_caliberated_pred_data );
figure(200);
scatter (new_exp_wear_data,new_caliberated_pred_data)
lsline; % add least squares regression line to scatter plot
xlabel('experimental')
ylabel('predicted')

Instead of lsline, you could use...

hold on;
plot(x, yFitted);

Cool - I didn't know about that convenient function - lsline().
