MATLAB - Numerical Methods

Which of the following inputs is required when calling ode45 in MATLAB?

AA matrix to invert

BA symbolic expression

CA string with the variable name

DA function handle defining the differential equation

Step-by-Step Solution

Solution:

Step 1: Identify inputs for ode45
The first input to ode45 must be a function handle that defines the differential equation as a function of time and state.
Step 2: Eliminate incorrect options
Options A, C, and D are not valid inputs for ode45. It does not take matrices to invert, variable names as strings, or symbolic expressions directly.
Final Answer:
A function handle defining the differential equation -> Option D
Quick Check:
ode45 input = function handle [OK]

Quick Trick: Always pass a function handle as first argument to ode45 [OK]
