compute_residual

Array<cfloat, 3> compas::compute_residual(CudaContext ctx, Array<cfloat, 3> lhs, Array<cfloat, 3> rhs, float *objective_out = nullptr)

Returns the result of lhs - rhs.

Additionally, if objective_out is provided, this function writes the sum over the squares of the differences between lhs and rhs to objective_out.

Parameters:

• ctx – CUDA context.

• lhs – The left-hand side.

• rhs – The right-hand side.

• objective_out – Optionally, pointer to where the sum over the squares of the differences must be stored.

Returns:
