Draw mode shape using Eigen values for a building

I calculated the Eigen values and Eigen vectors for the building in matrix form,

please guide me now, how can i plot the mode shape using the eigen values.

[Van Tien Nguyen]

Hi, can you please enchange your code to calculate eigenvalues and eigenvector for building?

Thank you in advance.

You have the Eigenvectors right...... plot them using plot command.

how can i introduced the height of the building along which i plot the modes?

sir actually i am not getting your point so please tell me here is my problem details,

order Eigen values

8 0.4238

3 0.5534

9 1.5700

2 1.9573

7 4.9026

1 5.6106

6 71.943

5 194.97

4 523.18

eigen vector

three storey building with each floor height 3 m.

i consider 3 degree per node degree of freedom.

[KSSV]

If V is an 9*9 Eigenvector.

plot(V(:,1))

KSSV sir,

i want to plot all these mode shape along the Y axis but as you told me i am not getting please elaborate it sir.
