MATLAB rookie help, How do i create a code to return these outputs?

My^''+By^'+Ky=x(t)

K = spring constant

B = dampening constant

M = mass

T = time

X = forcing function

Y = position of the mass

If you are given K, B, and M along with a table that gives values of x for a given t;

t (sec) [ 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2]

x ( kg m/s^2) [0 0 0.1 0.2 0.3 0.18 0.1 0 0 0 0]

Write a program that K, B and M are constant and supplied by the user input. Use T as the ending time value that solutions are sought ( also entered by the user when calling the function.

Initial values are t = 0 , y(0) = 0 , y’(0) = 0

The program outputs a flag ( runs without issue flag = 0) , t (vector of time values), y ( vector of position values), and yp ( vector of derivative values).

You've omitted a function declaration line at the top of the file. That will turn the file from a script file (which cannot return outputs) into a function file (which can.) Use the declaration of the myfun function as a model.

To return multiple outputs, use square brackets like the myfun function below.

[a, b] = myfun(5)

a = 25

b = 4

function [out1, out2] = myfun(in1)
out1 = in1.^2;
out2 = in1-1;
end

See this documentation page for more information.

That is just a sample program. Not what I’m trying to run. It’s just showing how to pass parameters to a sub function. I need a code to implement the equation based on values from the table
