**DATA >ATTRIBUTE**

**PURPOSE **Create a network from attribute data.

**DESCRIPTION **Convert a vector of valued attributes to a matrix based upon either exact matches, differences, absolute differences, squared differences, product or sums of the values.

**PARAMETERS**

**Dataset containing attribute vector: **

** **Name of data file containing vector of valued attributes. This vector must be a row or column of a matrix , it can be the only row or column. Data type: Matrix

**Vector is Row or Column?:**

** **Choose either row or column

**Which Row/Col** (Default = 1)

The number of the row or column that contains the attributes to be converted.

**Method: **(Default = Absolute Difference).

Choices are:

**Exact Matches **

Matrix X is formed by X(i,j) = 1 if vector(i) = vector(j) and 0 otherwise.

**Difference**

Matrix X is formed by X(i,j) = vector(i) - vector(j).

** Absolute Difference**

Matrix X is formed by X(i,j) = ABS (Vector(i) - vector(j)).

**Squared Difference**

Matrix X is formed by X(i,j) = (vector(i) - vector(j))^2.

**Product**

Matrix X is formed by X(i,j) = vector(i) * vector(j).

**Sum**

** **Matrix X is formed by X(i,j) = vector(i) + vector(j).

**Output dataset:**

Name of file which contains constructed matrix.

**LOG FILE **Constructed matrix.

**TIMING** O(N^2).

**COMMENTS** None.

**REFERENCES** None.
