We learned in the previous chapter that Ax=b need not possess a solution when the number of rows of A exceeds its rank, i.e., r<m.

As this situation arises quite often in practice, typically in the guise of 'more equations than unknowns,' we establish a rationale for the absurdity Ax=b.
We can write ρ=yiyi−2yiAikck+ciATikAklcl Taking the partial derivative, we have \[\frac{\partial \rho}{\partial ...We can write ρ=yiyi−2yiAikck+ciATikAklcl Taking the partial derivative, we have ∂ρ∂cj=−2yiAik∂ck∂cj+∂ci∂cjATikAklcl+ciATikAkl∂cl∂cj Now, \[\frac{\partial c_{i}}{\partial c_{j}}= …
