A MATLAB function that takes the vector spring constants and masses as inputs and returns the corre$-$

sponding vector of displacements for the fixed$-$free problem with three masses $($and three springs$).$

A MATLAB script that calls the function and displays the results on the Command Window for three

different cases:

$($a$)c_1=1,c_2=1,c_3=1$; and $m_1=1,m_2=1,m_3=1.$

$($b$)c_1=3,c_2=2,c_3=1$; and $m_1=1,m_2=1,m_3=1.$

$($c$)c_1=1,c_2=1,c_3=1$; and $m_1=0,m_2=0,m_3=1.$

All values shall represent quantities in a consistent set of units, such as $kg,\frac{N}{m},m$ and $\frac{m}{s^2}.$ Use the value

$g=1$ for the gravitational acceleration.
