Writes the header information for the calling Matrix to a stream.

Pascal
procedure WriteHeader(const Dst: TStream; Precision: TPrecision; Rounding: TRounding = rnTrunc); overload;
Description

Writes the header information for the calling object to a DstStream stream. The header information contains information about object (size, complex, type of values in Values array, ...) which all define the state of the object. Number type is defined by the Precision parameter. Rounding defines the rounding for integer types. When saving double precision as single precision, all overflows are saved as INF (-INF). When saving to integer types all overflows are clipped.

var b: Matrix; AStream: TFileStream; begin b.SetIt(2,2,False,[0,0,1,3,2]); AStream := TFileStream.Create('C:test.bin',fmCreate); try b.WriteHeader(AStream); // Write info for b b.WriteValues(AStream); // Write values of b finally AStream.Free; end; end;
