Overload List
| # | Signature | Description |
|---|---|---|
| 1 | function Equal(const Mtx: TMtx; Tolerance: Double): Boolean; | Compares two matrices. |
| 2 | function Equal(const Mtx: TMtx; Tolerance: Double; Compare: TCompare): Boolean; | Allows to specify the comparison method via the Compare parameter. |
Overload 1: function Equal(const Mtx: TMtx; Tolerance: Double): Boolean;
Compares two matrices.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Mtx | TMtx | |
| 2 | Tolerance | Double | scalar |
Returns: Boolean
Remarks:
Compares Mtx with the calling matrix and returns true if the matrices are equal (if all elements match in position and value). Tolerance defines the comparison tolerance. The maximum difference between elements may not exceed: +/-Tolerance. If Tolerance is omitted, a direct comparison algorithm is used.
Examples
var A,B: Matrix;
c: boolean;
begin
A.SetIt(2,2,false,[1,2,
2,4]); // 2x2, real matrix
B.SetIt(2,2,false,[1,2,
2,4]); // 2x2, real matrix
c := A.Equal(B,1e-8); // Check for differences bigger than 0.00000001
c := (A = B); // Check for an exact match
end;
