Write a Matlab code to determine the nodal displacements $x$ for the given truss system using a suitable solution to the system of equations in the form $Ax=b$ where $A$ features only beam area coefficients and $b$ has the from: $x=?\begin{array}{c}{x}_1\\ ?\\ x_8\end{array}?,b=\frac{L}{E}?\begin{array}{c}0\\ 0\\ ?\\ p\end{array}?$ To achieve higher marks for this task you will be required to write a code that is easily updatable (by changing array values) rather than directly typing in coefficient values in the A matrix. The size of A will be $8\times 8$, You may choose any solution method from the course: but explain why you chose it,
