createOctaveValue

abstract T createOctaveValue(int[] size)

read

public T read(BufferedReader reader)

The matrix formats, e.g. matrix come in two variants: after line with "type" the next line either starts with

• # ndims: specifying the number of dimensions and in the next line the lengths in all these dimensions and all the following lines the vectorized data, each in a separate line. This is read by readVectorizedMatrix(BufferedReader, String).
• # rows: specifying the number of rows and # columns: specifying the number of columns in the next line (which works only for matrices, i.e. up to dimension 2) and then for each row a line follows each of which holds the entries separated by a blank. This is read by read2dmatrix(BufferedReader, String).

Specified by:

read in class OctaveDataReader

Parameters:

reader - the Reader to read from, will not close reader

Returns:

the object read from reader.

readVectorizedMatrix

private T readVectorizedMatrix(BufferedReader reader,
                               String dimsLine)

readSizeVectorizedMatrix

private int[] readSizeVectorizedMatrix(BufferedReader reader,
                                       String ndimsLine)

Reads a line num of dims followed by a line of dimensions: integers separated by blank and returns an array with the according entries. In particular the length is num of dims.

read2dmatrix

private T read2dmatrix(BufferedReader reader,
                       String rowsLine)

readSize2dmatrix

protected int[] readSize2dmatrix(BufferedReader reader,
                                 String rowsLine)

Reads lines num of rows and num of cols and returns an array {nrows ncols}.
