I have force-time graph and I want to identify the baseline. How can I do this? Is there a function to find the baseline?

Since the baseline appears to be the minimum value, the min function may do what you want. There are similar functions that can extend that approach if you need to use them.

Maybe mask the signal to find values below a threshold and then take the mean
threshold = 10; % Or whatever.
baselineIndexes = abs(signal) < threshold;
baseLineValue = mean(signal(baselineIndexes));
yline(baseLineValue, 'Color', 'r', 'LineWidth', 2);
