How do I code for a matlab program?

I should write my MATLAM code as below.

The 10-kg rigid rod positioned on a frictionless surface as shown in the below figure and then released from that position t=0. When L=0.4m,g=9.81m/s2, answer the following problems. 2. Using MATLAB, calculate the change of angle , and plot them versus time (time span: 0 s0.3s). Submit the MATLAB codes you wrote along with the simulation results. The initial conditions of the are given as (0)=80 and (0)=0/sec. KHY_2018171031.m function KHY_2018171031() [time, cesult] = ode45(eeq, [ 10], [pi/6 ]); S's\% YOUR COOE HERE S\$S\% \% plot theta-t and theata_dot-t graph end | function dYdt =eq(t,x) SES YOUR COOE HERE S\$S\% \% compute dY/dt end
