Dear all,
When solving linear least squares in Matlab, can I get the matrix of partial derivatives numerically derived via Matlab, in a similar way to lsqnonlin ?

"Get it" from what? If it is linear least squares, i.e., you are minimizing
f(x) = |A*x-b|^2
don't you have the matrix A already? For a linear problem, A itself would be the matrix of partial derivatives (of the residuals).
