This MATLAB function returns the Inverse Tangent (tan-1) of the elements of X in radians.

P = atan(Z) returns the inverse tangent (arctangent) of the elements of Z.

Y = atand(X) returns the inverse tangent (tan-1) of the elements of X in degrees.

P = atan2(Y,X) computes the four-quadrant inverse tangent (arctangent) of Y and X.

P = atan2(Y,X) returns the four-quadrant inverse tangent (tan-1) of Y and X, which must be real.

D = atan2d(Y,X) returns the four-quadrant inverse tangent (tan-1) of Y and X, which must be real.

Description The atan and atanh functions operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are in radians. Y = atan(X) returns the inverse tangent (arctangent) for each element of X. For real elements of X, atan(X) is in the range .

February 4, 2026 - When the input x is imaginary and abs(x)>=1, the real part of the result differs from Scilab vs Matlab or Octave:

May 29, 2018 - Hello, I am solving a time derivative equation in Matlab. atan is part of the solution. It seems to behave strangely when atan(tan) is around. Although, I am not sure. I have attached the script...

July 23, 2013 - Y = atan(X) returns the inverse tangent (arctangent) for each element of X.

This MATLAB function returns the inverse hyperbolic tangent of the elements of X.

March 4, 2023 - ... Let us see an example related to arctanmatlab, for arctan we use a Matlab syntax as ‘atan’, atan is parenthesis we take that variable names or we directly take the equation for the inverse tangent.

June 5, 2017 - Maths/formula behind atan2 function. Learn more about vectors, atan2, dot, cross, angles, theta

October 1, 2022 - https://www.mathworks.com/matlabcentral/answers/1815610-what-the-difference-between-the-phase-and-arctan · Cancel Copy to Clipboard · Hi all · When z=x+iy. I know (if I am correct ) that tan^-1(y/x) = arctan(y/x) =atan(y/x) = atan2(y,x) we use these expression to find the angle (theta) that calculateing from the positive real axis to the vector between the origen and the point z.

Y = atan(X) returns the inverse tangent (arctangent) for each element of X.

March 10, 2023 - I do know the velocity as function of radius, so i can generate a NxN matrix containing the information, using the ''position_matrix''. So i only need the angles. I thought the atan(y/x) the best way to deal with this, however this only helps me to obtain the angles in 1 quarter of the plasma.

September 15, 2011 - https://www.mathworks.com/matlabcentral/answers/15898-atan-function · Cancel Copy to Clipboard · Hello,mycode is as follows: phi1= 0:1:360; beta=25; phi2= atand(cosd(beta)*tand(phi1)); error=phi2-phi1 · all angle are in degrees.

October 23, 2013 - https://www.mathworks.com/matlabcentral/answers/91160-how-can-i-fit-my-data-to-an-inverse-tangent-function#answer_972305 ... Don't know if you guys have solved the problem or not. As I understand, this fitting is to get the resonance frequency and quality factor out of a phase sweep. I figured out that the formula of y = atan(x*a/b/(a^2-x^2)) is not suitable for fitting in MATLAB due to the different period settings for the formula and the atan function in MATLAB.
