functionisEqual

Information

Syntax

Matrices.isEqual(M1, M2);
Matrices.isEqual(M1, M2, eps=0);

Description

The function call "Matrices.isEqual(M1, M2)" returns true, if the two Real matrices M1 and M2 have the same dimensions and the same elements. Otherwise the function returns false. Two elements e1 and e2 of the two matrices are checked on equality by the test "abs(e1-e2) ≤ eps", where "eps" can be provided as third argument of the function. Default is "eps = 0".

Example

  Real A1[2,2] = [1,2; 3,4];
  Real A2[3,2] = [1,2; 3,4; 5,6];
  Real A3[2,2] = [1,2, 3,4.0001];
  Boolean result;
algorithm
  result := Matrices.isEqual(M1,M2);     // = false
  result := Matrices.isEqual(M1,M3);     // = false
  result := Matrices.isEqual(M1,M1);     // = true
  result := Matrices.isEqual(M1,M3,0.1); // = true
