                           int cols)

Construct a new matrix of the given size

Parameters:

rows - Number of rows

cols - Number of columns

ReadWriteableMatrix

public ReadWriteableMatrix(Jama.Matrix data)

Construct a matrix using the provided matrix. The matrix data is assigned internally and is not copied.

Parameters:

data - the data
