subtract function
Subtracts vector b from vector a
@param {vec2} out the receiving vector @param {ReadonlyVec2} a the first operand @param {ReadonlyVec2} b the second operand @returns {vec2} out
Implementation
List<double> subtract(List<double> out, List<double> a, List<double> b) {
out[0] = a[0] - b[0];
out[1] = a[1] - b[1];
return out;
}
