Method Detail

readMatrix

public DoubleMatrix2D readMatrix(java.lang.String theFile,
                                 int rows,
                                 int cols)

Load a matrix from a file...this is just the same as the dense loader for now...need to change this.

Parameters:

theFile - the name of a file on disk with row-oriented matrix

rows - number of rows

cols - number of columns

Returns:

a DoubleMatrix2D mirroring the contents of the file

readMatrix

public DoubleMatrix2D readMatrix(java.lang.String theFile)

read a sparse matrix into memory from disk...again, this is the same as the dense method. this method doesn't require us to specify the number of rows and columns...but we have to read through the file twice

Parameters:

theFile -

Returns:

a sparse matrix
