.Modelica.Blocks.Math.Pythagoras .Modelica.Blocks.Math.PythagorasThis block determines the hypotenuse y = sqrt(u1^2 + u2^2)
if the boolean parameter u1IsHyotenuse = false.
In this case the two inputs u1 and
u2 are interpreted as the legs of a right triangle
and the boolean output valid is always equal to
true.
If u1IsHyotenuse = true, input u1 is interpreted as hypotenuse and u2
is one of the two legs of a right triangle.
Then, the other of the two legs of the right triangle is the output, determined by
y = sqrt(u1^2 - u2^2), if u1^2 - u2^2 ≥ 0; in this case the
boolean output valid is equal to true. In case of u1^2 - u2^2 < 0, the
output y = 0 and valid is set to false.
