type "pathtool" in your MATLAB command window, add the path of the functions e.g. if your operating system is Windows, add "...\libsvm-3.17\windows" and then save. MATLAB can read them now. That's all.

libsvmread() is part of the third-party libsvm tools. See https://www.mathworks.com/matlabcentral/answers/8704-i-can-not-use-libsvm#answer_12007
