Hello,
You can use the eigs routine from ARPACK
http://help.scilab.org/docs/5.5.2/en_US/eigs.html
An example
A = sprand(1000, 1000, 0.02, "normal"); // creates a random sparse matrix of size 1000 x 1000 and density 0.02
[d, v] = eigs(A, [], 10, "SM"); // computes the 10 smallest eigenvalues of A
Hope it helps,
