matlab - FITCSVM not working the same as SVMTRAIN -


i have implemented svm classifier, using matlab function svmtrain, , classified set of test data, using svmclassify. used following code train classifier:

svmstruct = svmtrain(features, labels, 'options', options, 'boxconstraint', 10, 'kernel_function', 'rbf', 'rbf_sigma', 27, 'showplot', 'false')

i have set options parameter below:

options = statset('maxiter', inf)

since matlab stopping support svmtrain, tried move fitcsvm, has advised. used following code:

svmmodel = fitcsvm(features, labels, 'iterationlimit', inf,'boxconstraint', 10, 'kernelfunction', 'rbf', 'kernelscale', 27)

the problem latter converges fast, message exiting active set upon convergence due deltagradient., , when use predict function in order classify set of test data, not lead same results used svmtrain , svmclassify. may have caused problem? using fitcsvm function correctly?
