示例1: writeOmfBinary4

// Writes data in OMF Binary 4 format
func writeOmfBinary4(out io.Writer, array *dump.Frame) {
	data := array.Tensors()
	gridsize := array.Size()[1:]

	var bytes []byte

	// OOMMF requires this number to be first to check the format
	var controlnumber float32 = OMF_CONTROL_NUMBER
	// Conversion form float32 [4]byte in big-endian
	// Inlined for performance, terabytes of data will pass here...
	bytes = (*[4]byte)(unsafe.Pointer(&controlnumber))[:]
	bytes[0], bytes[1], bytes[2], bytes[3] = bytes[3], bytes[2], bytes[1], bytes[0] // swap endianess
	out.Write(bytes)

	// Here we loop over X,Y,Z, not Z,Y,X, because
	// internal in C-order == external in Fortran-order
	ncomp := array.Size()[0]
	for i := 0; i < gridsize[X]; i++ {
		for j := 0; j < gridsize[Y]; j++ {

					bytes = (*[4]byte)(unsafe.Pointer(&data[core.SwapIndex(c, ncomp)][i][j][k]))[:]
					bytes[0], bytes[1], bytes[2], bytes[3] = bytes[3], bytes[2], bytes[1], bytes[0]
					out.Write(bytes)
