func MultiExp

func MultiExp(scalars []fr.Element, points []bls12381.G1Affine, numGoRoutines int) (*bls12381.G1Affine, error)

MultiExp computes a multi exponentiation -- That is, an inner product between points and scalars.

More precisely, the result is set to scalars[0]*points[0] + ... + scalars[n-1]*points[n-1], where n is the length of both slices If the slices differ in length, this function returns an error.

numGoRoutines is used to configure the amount of concurrency needed. Setting this value to a negative number or 0 will make it default to the number of CPUs.

Returns an error if the numGoRoutines exceeds 1024.
