چکیده
Abstract We investigate the regional gradient observability of fractional sub-diffusion equations involving Caputo derivative. The problem consists describing a method to find and recover initial vector in desired region, which is contained spatial domain. After giving necessary notions definitions, we prove some useful characterizations for exact approximate observability. An example system that not (globally) observable but it regionally given, showing importance analysis. Our characterization notion given two types strategic sensors. recovery carried out using an expansion Hilbert uniqueness method. Two illustrative examples are show application developed approach. numerical simulations confirm proposed algorithm effective terms reconstruction error.

متن کاملFractional Derivatives, Fractional Integrals, and Fractional Differential Equations in Matlab
The term fractional calculus is more than 300 years old. It is a generalization of the ordinary differentiation and integration to non-integer (arbitrary) order. The subject is as old as the calculus of differentiation and goes back to times when Leibniz, Gauss, and Newton invented this kind of calculation. In a letter to L’Hospital in 1695 Leibniz raised the following question (Miller and Ross...
