WebThe four-quadrant inverse tangent, atan2(Y,X), returns values in the closed interval [–π, π] based on the values of Y and X, as shown in the graphic. In contrast, atan(Y/X) returns results that are limited to the interval [–π/2, … WebIf one of the arguments X and Y is a vector or a matrix, and another one is a scalar, then atan2 expands the scalar into a vector or a matrix of the same length with all elements equal to that scalar. If X = 0 and Y > 0, then atan2(Y,X) returns pi/2. If X = 0 and Y < 0, then atan2(Y,X) returns -pi/2.
