Information

Syntax

Vectors.find(e, v);

Vectors.find(e, v, eps=0);

Description

The function call "Vectors.find(e, v)" returns true if input e is in vector v. The test of equality is performed by "abs(e-v[i]) ≤ eps", where "eps" can be provided as third argument of the function. Default is "eps = 0".

Example

Real v[3] = {1, 2, 3};

Real e1 = 2;

Real e2 = 3.01;

Boolean result;

algorithm

result := Vectors.find(e1,v); // = true

result := Vectors.find(e2,v); // = false

result := Vectors.find(e2,v,eps=0.1); // = true
