Graph metrics analysis (average clustering coefficient, characteristic path length and diameter)

Hello everyone,

Attachment is a 30 x 30 metrics data. I want to performe Graph metrics analysis in this data.

Do anyone know to extract average clustering coefficient and characteristic path length and diameter (respectively, the average number of edges along the shortest paths and the largest possible distance, between all possible pairs of nodes) in this metrics data by easy Mathlab function/toolbox or code.
