If it is able to implement segmentation
Does this code increase speed?
If the binary can be segmented after reading, can the following JSL be used?
ar[0, 3] = Blob To Matrix( b, "int", 4, "little", 8 )[0, 1];
ar[0, 4] = Blob To Matrix( b, "int", 4, "little", 8 )[0, 2];
ar[0, 5] = Blob To Matrix( b, "float", 4, "little", 8 )[0, 3];
