# vec2mat

0th

Percentile

##### Auxiliary function, produces matrix from vector

The number of elements of vec are the number of non-zero elements in the adjacency matrix. It performs the opposite operation of mat2vec.ix.

##### Usage
vec2mat(vec, directed, selfloops, n)
##### Arguments
vec

vector to be put in matrix form

directed

a boolean argument specifying whether object is directed or not.

selfloops

a boolean argument specifying whether the model should incorporate selfloops.

n

vector. if length(n)==1, n is the number of vertices. If length(n)==3 first element is number of vertices, second and third elements are number of vertices for row and column of bipartite matrix.

##### Value

matrix nxn generated from vector.
