MATLAB: Can lab color space normalize

color spaceimage processrgb2lab

as we all know, the range of lab color space is (0.100) (L), (-127,128) (A,B). so can I normalize them into (0,1) or any other range? and does it have any influence?

Not really, this is a convention but like all colour encoding you can use whatever range you wish as long as you define what that range is. The (-128, 127) range was chosen because that's the range of signed 8 bit integers.
While you can use whatever range you wish for your own processing, those matlab functions that expect L*a*b* values expect them to be in the conventional range (0,100) for L* and (-128, 127) for the others. These functions will not work properly if you use a different convention.
