Matrix.SetIt Method

Overload List

#	Signature	Description
1	TMtxVec SetIt(Int32 Index, Double[] A)	Sets object values.
2	TMtx SetIt(Int32 ARows, Int32 ACols, Boolean AComplex, Double[] A)	Sets matrix values.
3	TMtxVec SetIt(Int32 Index, Int32 AIndex, Int32 Len, Double[] A)	The elements of A array, starting at aIndex, are copied to the calling object elements, starting at Index.

Overload 1: TMtxVec SetIt(Int32 Index, Double[] A)

Sets object values.

#	Name	Type	Description
1	Index	Int32	start index
2	A	Double[]

Result: stored in self (calling object), returns self for chaining

Remarks:

Set object values. Method call does not change object's size or Dew.Math.Matrix.Complex property, but it does check for array overrun. The elements of A array are copied to the calling object elements, starting at Index. If the calling object is complex, then real parts of complex numbers are on even (0,2,4..) and imaginary parts on odd indexes.(1,3,5,..).

Overload 2: TMtx SetIt(Int32 ARows, Int32 ACols, Boolean AComplex, Double[] A)

Sets matrix values.

#	Name	Type
1	ARows	Int32
2	ACols	Int32
3	AComplex	Boolean
4	A	Double[]

Result: stored in self (calling object), returns self for chaining

Remarks:

Sets matrix values. This method gives you the possibility to pass large arrays of elements without having to declare constant arrays. Pass all elements in A array to the calling matrix. The Dew.Math.Matrix.Rows and Dew.Math.Matrix.Cols properties of the calling matrix are set to ARows and ACols and the Dew.Math.Matrix.Complex property is set to AComplex. An exception is raised if the matrix size (ARows*ACols) does not match the number of complex numbers in A.

Examples

Matrix A;
A.SetIt(2,2,false,[1,2,
2,4]);

Overload 3: TMtxVec SetIt(Int32 Index, Int32 AIndex, Int32 Len, Double[] A)

The elements of A array, starting at aIndex, are copied to the calling object elements, starting at Index.

#	Name	Type	Description
1	Index	Int32	start index
2	AIndex	Int32	start index
3	Len	Int32	element count
4	A	Double[]

Result: stored in self (calling object), returns self for chaining

Remarks:

If the calling object is complex, then real parts of complex numbers in the A array are on even (0,2,4..) and imaginary parts on odd indexes.(1,3,5,..).
