MATLAB with all steps please, screenshots or something

Consider a 5-story 1-bay frame building (L_beam=5m, h_col=3m). Flexural stiffness for all members(beamsand columns) is EI=10000 ton-m². Axial stiffness can be considered as rigid. Seismic weight is 20 ton per story.

a)Calculate the mass matrix (5x5).

b)Calculate the lateral stiffness matrix (5x5) by static condensation of non-dynamic DOF.

c)Solve the eigenvalue problem and calculate the mode shapes and corresponding periods.Followthe format introduced in lecture to present the mode shapes.

d)Sketch the modeshapes
