I have the hyperspectral radiance value, How can I convert the radiance value into reflectance?

I have the hyperspectral radiance value from the "AVIRIS" sensor with respective wavelengths , How can I change it to the reflectance value?

You can make use of the function “radiance2Reflectance” to compute the reflectance value from radiance value. This MATLAB documentation demonstrate the use of the “radiance2Reflectance” function. Additionally, the documentation includes the mathematical formula used to compute the reflectance value.
