You could use the Image Processing Toolbox function raw2rgb to convert your raw NEF to sRGB values, and then you could use the rgb2lab function to convert to CIELAB.
Note that function raw2rgb implements one particular way to convert from the raw color filter array (CFA) values to RGB. It's not the only way to do it. If you want to get the CFA values directly, then use rawread.
