Version Published Release Notes Action
1.6.0.0

Moved the beginning part of the code with nargin from function checkInputs_tvtp() to the beginning of the main function MS_Regress_Fit_tvtp.m. The old code returned error message when the newer (2017 or later) edition of Matlab is used.

1.5.0.0

1) Brett Sumsion of Dupont Capital Management kindly modified Marcelo's c++ filter to be used with the tvtp code here.
2) Added Tomlab optimizer as an alternative optimization tool.

1.2.0.0

Add explanation to the tvtp matrix notation.
Add Tomlab as an alternative for optimization.
