stopfcn problem in tfocs_iterate.m

[bradicator]

TFOCS v1.4
MATLAB version 9.0 (R2016a) on MACI64

Hi, in v1.4 and the current version on github, in file tfocs_iterate.m, line 85,
if isa(stopFcn,'function_handle') % added Oct 27 '14 is wrong. The reason is because by the design in tfocs_initialize.m, stopFcn is a cell containing function_handle rather than function_handle itself. The fix is
if isa(stopFcn{err_j},'function_handle'). One does not need to run the program to verify this; reading the context of this line is convincing enough. The consequence of this bug is that user defined stop functions never run...

Best,
Brad

You're right, good catch. Thanks! Just pushed the fix to github
