核方法工具箱，包括核典型相关分析KCCA，KPLS等算法的源码和实现。(Kernel Methods Toolbox KMBOX includes implementations of algorithms such as kernel principal component analysis (KPCA), kernel canonical correlation analysis (KCCA) and kernel recursive least-squares (KRLS). )

相平面分析的matlab程序例子，希望对大家有用(Phase plane analysis matlab program examples, we hope to be useful)

基于matlab的数字计算资料，既有程序也有案例，最新最全。(This book is a survey of the numerical methods that are common to undergraduate courses in Science, Computing, Engineering and Technology. The aim is to present sufficient methods to facilitate the numerical analysis of mathematical models likely to be encountered in practice. Examples of such models include the linear equations describing the stress on girders, bridges and other civil engineering structures, the differential equations of chemical and thermal reactions, and the inferences to be drawn from observed data.)
