Matlab atan2= 2.8438364863237604. C atan2= 2.8438364863237608. I have tried to even write mex files that implement the cos, sin and atan2, and I even put the whole computation that I am doing in a mex file and the result is the same. I have set the compiler of the mex file to be the same as the one from C and still, the difference is there.

29 Mar 2007 It would be easy enough to implement if I had an atan function, but, alas, I lack that one too. All I have are the "regular" sin, cos and tan. I can't

float z = y/x;. if ( fabs( z ) < 1.0f ). {. atan = z/(1 .0f + 0.28f*z*z);. atan2 vs atan That is, if you know the x horizontal and the y vertical, or the x The syntax for the atan2 function in the C Language is: double atan2(double y,  atan2.

The atan2() function divides the first argument by the second and returns the arc tangent of the result, or arctan( y / x ) . The return value is given in radians, and 

I have set the compiler of the mex file to be the same as the one from C and still, the difference is there. ATAN2 Function in C Example. The atan2 function in the math library helps you to find the trigonometric Arc Tangent of multiple parameters.

The Math.atan2() method is used to return the arctangent of the quotient of its arguments. The Math.atan2() method returns a numeric value between -Π and Π representing the angle theta of an (x, y) point and the positive x-axis. This is the counterclockwise angle, measured in radians, between the positive X-axis, and the point (x, y). Syntax:

atan is tan inverse, that is, gives you the angle given the tan. When you call atan (tan (a+2*pi)), the answer will be a.
