Find

Declaration:	TMatrix.Find (LowCol, HighCol, LowRow, HighRow: integer; Value: double; var ColIx, RowIx: integer);
The method Find searches the matrix element which is closest to Value and returns the index of the found element in the variable parameters ColIx and RowIx. The search range is specified by the parameters LowCol, HighCol, LowRow and HighRow.

Hint:

Setting both the low and high parameter of a dimension (i.e. LowCol and HighCol) to zero values forces a search through all elements of that dimension. For example, the call of Matrix1.Find (2,3,0,0,2.31,ix,iy); searches all rows of columns 2 and 3 of the matrix Matrix1 for the closest value to 2.31 and returns the address of the found cell in the variables ix and iy.
