Almost all math-related problems in engineering and science are more complicated than the ones we have seen in single variable calculus. The objects in nature usually are affected by many other ...

Learn to choose coordinate systems, visualize multivariable functions, and parameterize curves. You can use these live scripts as demonstrations in lectures, class activities, or interactive ...

This toolkit is a Python-based library designed to help computations in multivariable calculus. It provides classes and methods for differentiating expressions, computing gradients, finding unit ...

Abstract: A method of generating a multivariable positive real function (MPRF) from the given multivariable real part is presented. The constraints on the given real part, in addition to its ...

Abstract: Far function difference approximation is one of the most active research contents in function approximation theory at present. Compared with unary function approximation, there are many ...

Territorial Differential Meta-Evolution (TDME) is an efficient, versatile, and reliable algorithm for seeking all the global or desirable local optima of a multivariable function. It employs a ...

Recent advances in estimation techniques have underscored the growing importance of shrinkage estimation and balanced loss functions in the analysis of multivariate normal distributions. These ...
