I want to clear all symbols but i want to keep just J and GradientDescent in this group.
A i n x x4 \[Alpha]$ $3 $8
bfp J n$ X X$ \[Theta] $4
cp lp predict1 x1 y \[CapitalTheta] $5
ex1data1 m predict2 x2 y$ \[Theta]$ $6
GradientDescent m$ sf x3 \[Alpha] \[CapitalTheta]$ $7
Is there a clever way to achieve this rather than use
ClearAll[A, i, n, ...]
ClearAll @@ DeleteCases[Names["Global`*"], "GradientDescent" | "J"]
ps. It is not really a good idea to use variables that start with UpperCase letter.
Oh, it's brillant. Thanks!
For the upper case letter, it's just a convention, not an obligation :P.
