I have x,y value and they form a polyline ,how can i find the slope of each line without putting any manual efforts?

Sometimes the number of line forming from the data is not easy to interpret.I have to automate the process so that it can pick the number of polyline the data is forming and slope of each line.

If you have a polyline and want the slope or angle of each segment, consider the simple example:
% vertices of a polyline (this case is a closed polygon, but w/e)
x = [0 1 0.5 0];
y = [0 0 sqrt(3)/2 0];
% segment slope and angle
slope = diff(y)./diff(x)
slope = 1×3
0 -1.7321 1.7321
theta = atan2d(diff(y),diff(x))
theta = 1×3
0 120.0000 -120.0000
% plot it

Basically all I need to know is how to segment wise fit data?
