Hey Dear All,
I would like to refer to the Values of an excel file in my code.
The value which I should read from the excel file is a function of two parametrs (PN and DN) which I include then on my matlab subroutine.

My code should be able to recive a DN and a PN and then give the revelant value.
I would appreciate to have your support.

Until you have read some of the file, you cannot know which row corresponds to which DN value.
And no, it is not possible to do something like
readmatrix(filename, 'column', 5, 'row', findrow('column', 1, 'eq', 0.3))
You need a database to make queries like that.
