i have a line, its a sigmoid function. the code is like this
x = 0:0.1:10;
y = sigmf(x,[2 4]);
xlabel('sigmf, P = [2 4]')
i want to know every angle between each pair of point and the x axis. i mean for line y of x=0 and x=0.1, the angle is..
for line y of x=0.1 and x=0.2 the angle is...
how can i calculate that? thank you before!
