what is the code in MATLAB with an explanation please?

4.8 A uniform beam is freely hinged at its ends x = 0 and x = L, so that the ends are at the same level. It carries a uniformly distributed load of W per unit length, and there is a tension T along the r-axis. The deflection y of the beam a distance x from one end is given by WEI cosh[a(L/2 - x)] y = T2 cosh(aL/2) 1-1] WX(L - x) + 27 where a =T/ET, E being the Young's modulus of the beam, and I is the moment of inertia of a cross- section of the beam. The beam is 10 m long, the tension is 1000 N, the load 100 N/m, and El is 10% Write a script to compute and plot a graph of the deflection y against X (MATLAB has a cosh function). To make the graph look realistic you will have to override MATLAB's automatic axis scaling with the statement axis( [xmin xmax ymin ymax]) after the plot statement, where xmin etc. have appropriate values
