Runge kutta second order method

Webb29 okt. 2024 · Here is the Runge-Kutta code. % Note that F function expression is defined via Function Handle: F = @ (x, y) (x+y) The inital values used to be correct. The un altered code looks like this. I am simply trying to use a second order ODE and enter it in the form of a matrix/vector rather than a 1 dimensional value. Webblsode (cont’d) I The method used by Octave is an adaptive step-size method. I That is, the actual step-size (value of h) used varies as the integration proceeds based on the behavior of the function. I In particular, the values in the t vector do not determine the step size, but are there only for evaluation and plotting purposes. I In particular, if one only wanted to …
