function dydx = pdb(x,y)
dydx=(-2*x^3)+(12*x^2)-(20*x)+(8.5);
%runpdb.m
clear
clc
rentang_x = [0 4];
y0 = 1;
[x,y] = ode23('pdb',rentang_x,y0);

xlabel('x')
ylabel('y')
the error is

How are you running your code?
That is a function that takes arguments, not a script, so you must call it from the command line (or another script/function/class) passing arguments into it as e.g.
pdb( 6, 7 );
rather than just clicking 'Run' on the .m file.
