Atan atan2
Web1 day ago · math. atan2 (y, x) ¶ Return atan(y / x), in radians. The result is between -pi and pi. The vector in the plane from the origin to point (x, y) makes this angle with the positive X axis. The point of atan2() is that the signs of both inputs are known to it, so it can compute the correct quadrant for the angle.

WebSep 17, 2024 · There are perfectly good reasons why you might be interested in allowing for any angle between -pi and pi. It's just that, if you don't make the -pi/2,pi/2 restriction then MATLAB won't recognize that atan2(sin(alpha),cos(alpha))=alpha. Under your assumption that alpha is between -pi and pi, it should recognize that, but for some reason it doesn't.

WebDescription. Returns the angle in radians whose Tan is y/x. Return value is the angle between the x-axis and a 2D vector starting at zero and terminating at (x,y). Note: This function takes account of the cases where x is zero and returns the correct angle rather than throwing a division by zero exception.
