You can increase the maximal number of iterations. See 'options' in the doc or help for svmtrain.

thank you for answer i increase MaxItr to inf, but did not fix the error.

Then do one or all of:

  • lower the box constraint
  • increase tolkkt
  • specify a positive value for kktviolationlevel
  • try a different kernel function
