WebGradient Intersection method: This method uses SCADA (Supervisory Control and Data Acquisition) values to calculate the theoretical … WebThen there is exactly one vector that minimizes J ( p) and this vector is the solution of the linear equation, (57) A p = b. The proof of this statement is straightforward. Let us compute the gradient of J: ∇ J = A p − b. To get the above expression we have used A = A T. The gradient of J is therefore equal to zero if A p = b.
