| Function | Description |
|---|---|
vec_add(a, b) |
Element-by-element addition |
vec_sub(a, b) |
Element-by-element subtraction |
vec_mul(a, b) |
Element-by-element multiplication |
vec_div(a, b) |
Element-by-element division |
vec_pow(a, b) |
Element-by-element exponentiation |
Examples
-- Array + Array
SELECT vec_add(ARRAY[1,2,3], ARRAY[10,20,30]); -- {11,22,33}
-- Array * Scalar
SELECT vec_mul(ARRAY[1.0, 2.0, 3.0], 2.0); -- {2.0, 4.0, 6.0}
-- Scalar - Array
SELECT vec_sub(10, ARRAY[1,2,3]); -- {9,8,7}Last updated on
