For help, n [I] is plural, originally now I change to a diagonal matrix, should how to extract?

Before and I don't know, how to judge, map2 is a function of their own definition? Layer material and lenda is what?

CodePudding user response:

map2 and these parameters are not important, is defined, because n [I] is a scalar originally, now to the diagonal matrix so wrong, want to ask how to put the full n extracted.
