MATLAB: Solve sixth-order ODE in matlab

boundary conditionssixth-order ode

Hi every one,

I want to solve a sixth-order ODE like y(6) + 2y(4) + y(2) = f(x) with 6 boundary conditions. Could anybody can help me?

Thank you in advance!

Use - depending on your boundary conditions - ODE45 or BVP4c and set up the system as

y1'=y2

y2'=y3

y3'=y4

y4'=y5

y5'=y6

y6'=-2*y5-y3-f(x)

Best wishes

Torsten.

Use MATLAB's "bvp4c" instead of a code that you don't understand.

MATLAB: Does the TAYLOR function within the Symbolic Math Toolbox return incorrect results for sixth (or higher) order polynomials

This has been verified as a bug in the Maple kernel accessed by the Symbolic Math Toolbox in the way that the TAYLOR function generates taylor expansions.

As a workaround, you can use the Extended Symbolic Math Toolbox:

maple('Order:=10;')
taylor(x^6, 7)

which produces the expected result:

x^6
