Department of Mathematics, Shahid Rajaee Teacher Training University, Tehran, Iran. In mathematics, a Green’s function is the impulse response of an inhomogeneous differential equation defined on a ...

Abstract: This study presents a spectral method for solving the two-dimensional variable-order fractional optimal control problems (2D-VOFOCPs). In this work, a dynamic system with variable-order ...

Just like when we derive functions, we can integrate functions with a general formula."," Integration can be a bit more complex, so this formula won't necessarily work for every function you encounter ...

The input argument fun refers to an IML module that specifies a function that returns f, a vector of length m for least-squares subroutines or a scalar for other optimization subroutines. The returned ...

Abstract: In this paper, we propose a subspace method for solving unconstrained optimization problems without derivatives. In each iteration, we construct a subspace, which enables a large-scale ...

This study is an attempt to analyze students' construction of function based problem solving methods in introductory algebra. It claims that for functions to be a main concept for learning school ...
