[Solved] Identify the error in this code snippet:f = @(y,t) y^2 - t; [t,y] = ode45(f, [0 1], 0); plot(t,y); — Ans: Function handle arguments are in wrong order. | MATLAB

MATLAB - Numerical Methods

Identify the error in this code snippet:

f = @(y,t) y^2 - t;
[t,y] = ode45(f, [0 1], 0);
plot(t,y);

ATime span must be a column vector.

BInitial value cannot be zero.

CFunction handle arguments are in wrong order.

DPlot command is missing labels.

Step-by-Step Solution

Solution:

Step 1: Check function handle argument order
ODE functions for ode45 must have arguments in order (t,y), but here it is @(y,t), which is incorrect.
Step 2: Verify other parts of the code
Initial value zero is allowed, time span as [0 1] is valid, and plot labels are optional, so these are not errors.
Final Answer:
Function handle arguments are in wrong order. -> Option C
Quick Check:
Function handle must be @(t,y), not @(y,t) [OK]

Quick Trick: Always use @(t,y) for ode45 function handles [OK]
