Let's suppose I have bunch of random points as shown in the figure below. Now, is there any algorithm in matlab that would draw a straight line through these points as long as the distance from this line to all points along the line is less than a threshold value (d<threshold)

See my polyfit() demo, attached below the image.
You will have to do two passes. One to get the line, then get the distances, then delete the data points that are too far, then run it again on the remaining points.
