Description

Copy a subset of this matrix specified by 0 based column and row indices to a worksheet object

Syntax

BOOL CopyTo( Worksheet & wksTarget, int r1 = 0, int c1 = 0, int r2 = -1, int c2 = -1, int nr1Wks = 0, int nc1Wks = 0, BOOL bTransposed = TRUE, BOOL bSetColumnTypes = TRUE )

Parameters

wksTarget: [output] worksheet object to receive result
r1: [input] Begining row index, default is 0 (0 based offset)
c1: [input] Begining column index, default is 0 (0 based offset)
r2: [input] Ending row index, (inclusive) default -1 is GetNumRows -1 (0 based offset)
c2: [input] Ending column index, (inclusive) default -1 is GetNumCols -1 (0 based offset)
nr1Wks: [input] Begining row index of receive worksheet, default is 0 (0 based offset)
nc1Wks: [input] Begining column index of receive worksheet, default is 0 (0 based offset)
bTransposed: [input] if bTransposed = TRUE, Copy transposed matrix to worksheet
bSetColumnTypes: [input] if bSetColumnTypes = TRUE, will set worksheet column datatype same as matrix

Return

Returns TRUE on successful exit and FALSE on failure.
