Class MiscArrays

java.lang.Object
  dk.dmi.jog.MiscArrays

public final class MiscArrays

extends Object

Static methods for various array operations. Missing values must be represented by Float.NaN.

Method Summary

static List	asList(float[] f) Returns a fixed-size list backed by the specified array.
static List	asList(float[][][][] f) Returns a fixed-size list backed by the specified array.
static float[]	interpolateCenteredLinear(float[] a) Returns a version of the argument array with missing values interpolated using a centered linear interpolation.
static float[]	interpolateLeftLinear(float[] a) Returns a version of the argument array with missing values interpolated using a one-sided linear interpolation.
static float[][][][]	mask(float[][][][] d, boolean[][][][] m) Returns a 4-dimensional float array identical to the first argument but with data values set to Float.NaN where the second argument is false

Method Detail

asList

public static List asList(float[] f)

Returns a fixed-size list backed by the specified array.

Parameters:

f - the array by which the list will be backed.

Returns:

a fixed-size list backed by the specified array.

asList

public static List asList(float[][][][] f)

Returns a fixed-size list backed by the specified array.

Parameters:

f - the array by which the list will be backed.

Returns:

a fixed-size list backed by the specified array.

interpolateCenteredLinear

public static float[] interpolateCenteredLinear(float[] a)

Returns a version of the argument array with missing values interpolated using a centered linear interpolation. No extrapolation is performed.

Parameters:

a - array to be interpolated.

Returns:

a version of the argument array with missing values interpolated using a centered linear interpolation.

interpolateLeftLinear

public static float[] interpolateLeftLinear(float[] a)

Returns a version of the argument array with missing values interpolated using a one-sided linear interpolation. (Not implemented).

Parameters:

a - array to be interpolated.

Returns:

a version of the argument array with missing values interpolated using a one-sided linear interpolation.

mask

public static float[][][][] mask(float[][][][] d,
                                 boolean[][][][] m)

Returns a 4-dimensional float array identical to the first argument but with data values set to Float.NaN where the second argument is false

Parameters:

d - input data.

m - input mask.

Returns:

a 4-dimensional float array identical to the first argument but with data values masked out where the second argument is false
