CopyFromVec

Declaration:

TMatrix.CopyFromVec (Src: TVector; FirstElem, LastElem, DestCol, DestRow: integer; AsColumn: boolean);

The method CopyFromVec copies a part of the vector Src into its own data area (self). The elements to be copied are specified by the the parameters FirstElem and LastElem. The orientation of the vector is controlled by the parameter AsColumn. If AsColumn is TRUE the vector data are copied into a column of the matrix, otherwise the vector is copied a row. The destination position is defined by the parameters DestCol and DestRow. The element [DestCol, DestRow] is filled by the value of the source vector at address [FirstElem, LastElem] and all other elements are copied to higher addresses accordingly.

Hint:

FirstElem needs not to be lower than LastElem since the method CopyFromVec automatically allows for the correct copying sequence.
