Need some help with a Matlab task

For the two-support beam shown below, you need to calculate and plot the Deflection is the movement of the beam downward due to external forces applied. This deflection is solved in terms of a discontinuous piecewise function, also known as a singularity function. Another engineer you need below beam's deflection under the given loads. has already derived the equations 1200 lb 60 Ib/in. For some given number a, a point where forces change on a beam, the singularity function is defined as: x - a-(-a)xa 0, The below deflection equation, v(y), was deriv ed using the free-body-diagram above and contains two singularity functions. v( x) 3.198 10 (800x3-13.7x 10%-2.5x4 + 2.5(x-120)" + 600(x-240)3 TASK 2:17-25 min) Write a user defined function named MA3 Deflection_courgarnetlID.m which has one input (position x) and one output, (deflection v) You will need to apply the equation above with the discontinuity conditions described. Use this function to determine the deflection at the position entered. Produce a formatted output to the command window that states the deflection at the point entered
