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?

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
