Dearl all, I have to normalize a matrix to some number (512).
Exactly, my question is related to feature descriptor matrix which I want to normalize to 512. Actually, I have to import feature descriptor into another program that only accepts feature descriptors that are normalized to 512. But I don't get how to normalize the feature descriptor matrix or what does it mean by normalized to 512. I found normalize function in matlab but I don't know how can I use it for this purpose.
Below is the exact line what program asked and I have to do.
[Descriptor Data] is a npoint x 128 unsigned char matrix.
Note the feature descriptors are normalized to 512.
