Good evening all!!
For an assignment I am given an array of data that Imust "scale so the first value is zero"
I tried using:
arrayn=normalize(array,'norm',1);
but got the error:
Undefined function 'normalize' for input arguments of type 'double'.
I feel like i am missing something obvious. Why wouldn't the normalize function work on doubles? do i have to convert the whole array?
Thank you

normalize() is R2018a or later and you are using R2017b. For releases before that you can use mat2gray()
However I suspect you are intended to write the equivalent code yourself.
