... most problems in robotics, vision, and arguably every other science or endeavor take on the form of optimization problems. One is that the desired goal may not be achievable, and so we try to ... are said to be -conjugate or -orthogonal to each other. We will henceforth simply say “conjugate” for brevity. In summary, if we can find directions p p that are mutually conjugate, and if w...

... In other words, the curve-to-curve transformation from circle to ellipse is unique, but the point-to-pointtransformation is not. Matrices represent point-to-pointtransformations. The eigenvalue ... repeated for the last equation, therefore forcing , and so forth. In summary, the equation x x impliesthat , that is, that the vectors x x are linearly independent. For Hermitian matrices (an...
