Output atan(u1/u2) of the inputs u1 and u2
Blocks/Math
This blocks computes the output (right port) as inverse tangent of the first input (upper left port) divided by the second input (lower left port):
u1 and u2 shall not be zero at the same time instant.
Atan2 uses the sign of u1 and u2 in order to construct the solution in the range:
whereas block Atan gives a solution in the range:
Atan2 can be expressed as follows:
