%i need help with my getder file which take the derivative of the funtion.
%there are 3 file main where define all variables getder which i obtain the derivative
%and box_solve to solve and create a plot using eulers or RK method.
%Many thanks in advance
%main file
v0 = 0;
s0 = 0;
m = .5;
k = 75;
%getder file to obtain a the derivative
function xdot = getder(t,x)
x = [s;v];
a = (1/m)*(25*sin(45*t)-k*so);
xdot = [s;a];
%box_solve file to solve equation through euler method or Rk.
function [t,x] = box solve(x0,tlim,dt,solve_type)
if st == 1 %solve type allow operator to
t = (to:dt:tf).'
L = length(t);
x = xeros([l,2])
x(1,:) = xo.'
for n =1:L
x(n+1,:) = x(n,:)+dt*geter(t(n),x(n,:));

%if true
x = zeros(1,2);
There is no xeros function im matlab

%if true
function [t,x] = boxsolve(x0,tlim,dt,solve_type)
Function names must not contain spaces in matlab. It must be continuous
