MATLAB style array initialization in bash

Question

I wanted to initialize a large array in bash, preferably using MATLAB style array initialization. For e.g. I want something similar to following

Declare an array with elements ranging from 0 to 1000 with the gap of 5

array=0:5:1000

I know you can achieve that in a for loop as following

for i in {0..1000..5}
do
done

But same does not work in the following case

array={0..1000..5}

syntax error: operand expected (error token is "{0..1000..5}")

In order to make an array assignment, you need to wrap the brace expansion in ().

array=({0..1000..5})
