Weblinalg.lstsq(a, b, rcond='warn') [source] #. Return 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 ... WebInitial point for the solution process, specified as a real vector or array. The 'trust-region-reflective' and 'active-set' algorithms use x0 (optional). If you do not specify x0 for the …
