Clone2DArray

Declaration:	Clone2DArray (InMat: TDouble2DArray; var TargetMat: TDouble2DArray): integer;
Copies the contents of the 2-dimensional array InMat to the array TargetMat. The array TargetMat is automatically resized to match the size of InMat. The function returns the following error codes:  0 ... everything is OK -1 ... the source array has zero size

Hint:

Please note that the statement "Mat1 := Mat2;" does not copy the contents of array Mat2 into array Mat1. It simply copies the pointer to Mat2 into the variable Mat1 which in effect means that both variables are using the same memory after the assignment.
