Matlab RGB to Lab Conversion: Manual vs. rgb2lab Function

Using Matlab to convert RGB(45.75, 120.11, 62.45) to Lab values through tristimulus conversion and directly using the 'rgb2lab' function produces identical results. This is because the 'rgb2lab' function internally relies on the same tristimulus conversion formulas to calculate Lab values. Therefore, whether you manually calculate or utilize the function, the resulting Lab values will be identical.
