MatrixTextUtilities()

Method Summary

static java.lang.String	bitSetToZeroOne(java.util.BitSet bitset, int numcols) Converts the BitSet bitset into a text matrix of {0,1}, of dimensions (bitset.size() / numcols) x numcols
static java.lang.String	booleanToZeroOne(boolean[][] bools) Converts boolean[][] into a String of a matrix of {0,1}
static double[][]	getMatrixFromString(java.lang.String s, int M, int N) Converts the String s to a double[M][N], truncating and padding as necessary
static java.lang.String	getMatrixString(double[][] array, int numDigits) Converts the double[][] array into a textual representation, entries delimited by spaces, rows by new lines, with numDigits of precision
static java.lang.String	getMaxPrecisionMatrixString(double[][] array) Converts the double[][] array into a textual representation, entries delimited by spaces, rows by new lines, with full precision.
static BitSetFixed	zeroOneToBitSet(java.lang.String s, int M, int N) Take a String s of an M x N matrix of {0,1} and converts it into a BitSet.

Method Detail

getMatrixFromString

public static double[][] getMatrixFromString(java.lang.String s,
                                             int M,
                                             int N)

Converts the String s to a double[M][N], truncating and padding as necessary

Parameters:

s -

M -

N -

Returns:

A double[][] of the matrix in the String s

getMaxPrecisionMatrixString

public static java.lang.String getMaxPrecisionMatrixString(double[][] array)

Converts the double[][] array into a textual representation, entries delimited by spaces, rows by new lines, with full precision.

Parameters:

array -

Returns:

A string representation of double[][] array

getMatrixString

public static java.lang.String getMatrixString(double[][] array,
                                               int numDigits)

Converts the double[][] array into a textual representation, entries delimited by spaces, rows by new lines, with numDigits of precision

Parameters:
