Pythagoras
Determine the hypotenuse or leg of a right triangle
Library
Modelica/Blocks/Math
Description
This block determines the hypotenuse y = sqrt(u1^2 + u2^2)if the boolean parameter u1IsHyotenuse = false.In this case the two inputs u1 andu2 are interpreted as the legs of a right triangleand the boolean output valid is always equal totrue.
If u1IsHyotenuse = true, input u1 is interpreted as hypotenuse and u2is one of the two legs of a right triangle.Then, the other of the two legs of the right triangle is the output, determined byy = sqrt(u1^2 - u2^2), if u1^2 - u2^2 ≥ 0; in this case theboolean output valid is equal to true. In case of u1^2 - u2^2 < 0, theoutput y = 0 and valid is set to false.
