Undefined function 'seqminopt' for input arguments of type 'function_handle'.

Hi

I'm using svm library especially svmtrain function. I get some error. When I use svmtrain function directly

   svmStruct = svmtrain(xdata,names,'kernel_function','polynomial','showplot',true);

then everything works just fine (Matlab find function without any problems, functions returns proper results) BUT when I write my own function and use some other functions from that package like for example seqminopt then I get information

Undefined function 'seqminopt' for input arguments of type 'function_handle'.

"seqminopt" is a function which "svmtrain" calls without any problem but I cannot calls it directly ? Why I get such error ? Do you know any good Matlab tutorial on the internet which explain how to implement , management , include , check etc. packages and libraries ?

Please help me :)

I guess that seqminopt is located in a folder called /private, which is a subfolder of the path of svmtrain. Then svmtrain can see it, but no function from another folder. This is the intention of /private subfolders.
