Spot operator: opSpot/mldivide Spot Home Page
opSpot/mldivide
 \  Backslash or left matrix divide.
 
    X = A\B is similar to Matlab's backslash operator. If A is a Spot
    operator and B is a vector, then in general X is computed as the solution to the
    least-squares problem
 
    (*)  minimize  ||Ax - b||_2.
 
    However, some Spot operators implement their own mldivide routines
    that determine exactly how a solution to (*) is obtained.  For
    example, the orthogonal operators (e.g., opWavlet) obtain X via
    A'*b.
 
    If A is a scalar and B is a spot operator, then X = opFoG(1/A,B).
 
    The least-squares problem (*) is solved using LSQR with default
    parameters specified by spotparams.
