atan2


considering the second quadrant ( where x<0 and y>0) as the first quadrant how will i use the function atan2(y,x) to calculate the directions


Earlier saw manu comments on thé usage of atan2(x,y) including how to obtain only positive values. I thank Édith for that.
My problem is that the second quadrant is the initial quadrant so i dont know how to make matlab to understand that.
I tried to do this.
Second quadrant(which is considérer as first) i did 90+ antan(y,x)
Third quadrant(which is considérer as second) i did 270+ antan(y,x)
Am i rigjt???
Fourth quadrant(which is considérer as third) i did + antan(y,x)
