How to include 'end' in a varibable to extract a subset of the original vector ?

vector = 1:200;

%i want to extract a subset of vector
vector1 = vector(1:end-18)

%but if define a separate variable (range) 
range =[1:end-18];
vector1 = vector(range);

%i got this: 
Error: File: Untitled Line: 4 Column: 11
Illegal use of reserved keyword "end".

how can i define range in order to not have an error?

"... if i want to define range before the definictiion of the vector..."

You could use an anonymous function:

rng = @(v)v(1:end-18); % range is defined!
vec = 1:200;
out = rng(vec)

out = 1×182

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
