Web5 May 2024 · Both seem to be able to be used to find optimal parameters for an non-linear function using constraints and using least squares. However, they are evidently not the same because curve_fit results do not correspond to a third solver whereas least_squares does. Can someone explain the difference? python optimization scipy Share Cite WebReturn the least-squares solution to a linear matrix equation. Computes the vector x that approximately solves the equation a @ x = b. The equation may be under-, well-, or over-determined (i.e., the number of linearly independent rows of a can be less than, equal to, or greater than its number of linearly independent columns).
