®=which is defined in Octave but not in Matlab. This had been fixed.
The linear_ok.m test case has been changed to test scale the problem so it is more difficult and to check the number of iterations for the solution.
The initial state used by l1_linear has been improved so that it is closer to a solution of the first order conditions. This reduced the number of iterations necessary.
The convergence criteria was changed to square root of average squared residual instead of square root of sum of squared residuals.
The updating of the relaxation factor was changed to occur when the line search parameter is greater than or equal .9. In addition, a constant divisor of four was used for the update.
The documentation was reorganized so that l1_newton_quad is below l1_quadratic and l1_newton_line is below l1_linear .
Remove usages of the
&=operator in linear_ok.m (it is defined in Octave but not in Matlab®).
