[Solved] Taking derivative of a function
Let F(p,q) be F(p,q) = sum(j, [ r(j) – sum(i, p(i,j)*q(i,j)) ]^2 ) Then dF/dp is the matrix A formed by elements A(i,j) = 2 * [r(j) – sum(k, p(k,j)*q(k,j))] * (-q(i,j)) dF/dq is the matrix B formed by elements B(i,j) = 2 * [r(j) – sum(k, p(k,j)*q(k,j))] * (-p(i,j)) 2 solved Taking derivative of … Read more
