Assuming the data matrix corresponding to each block is orthogonal, we find optimal stepsizes of BGD in closed form, which provably lead to asymptotic convergence rates twice as fast as GD with Polyak's momentum; this means, under that orthogonality assumption, one can accelerate BGD by just ...

Flag that switches between sparse and dense matrix generation, specified astrueorfalse. When you specify'Sparse',true, the generated function represents symbolic matrices by sparse numeric matrices. Use'Sparse',truewhen you convert symbolic matrices containing many zero elements. Often, operations on s...
The scaffold and the cells are assumed to be contained in a bioreactor with fluid perfusion. The differentiation of hMSCs into chondrocytes favors the production of extracellular matrix (ECM) and is influenced by fluid stress. The model takes deformations of ECM and PET scaffold into account. The...
[t,y] = ode89(odefun,tspan,y0,options)also uses the integration settings defined byoptions, which is an argument created using theodesetfunction. For example, set theAbsTolandRelToloptions to specify absolute and relative error tolerances, or set theMassoption to provide a mass matrix. ...

An ode object defines a system of ordinary differential equations or differential algebraic equations to solve. You can solve initial value problems of the form y′=f(t,y), f(t,y,y′)=0, or problems that involve a mass matrix, M(t,y)y′=f(t,y). Define aspects of the problem usi...

The first of these, "Bog" (God), is a direct imitation of Gavrila Derzhavin's spiritual odes (Echoes of Derzhavin continued to appear in Batyushkov's mature work, but as only one element of his own, highly individual, style). WikiMatrix Number of countries with projects (under UNIDO...
