Used to turn the asymmetric column stochastic matrix into a symmetric column stochastic matric.
1  sym.P(x)

x 

The function calculates the symmetric matrix from the asymmetric column stochastic matrix, leaving the diagonal unchanged and averaging m[i,j] and m[j,i] as (m[i,j]+m[j,i])/2. The computed average substitutes each pair of values in the new symmetric column stochastic matrix.
Returns a matrix.
