Parameters

d0

Type: ILNumericsDimSpec
Range specification along dimension #0.

d1

Type: ILNumericsDimSpec
Range specification along dimension #1.

Type: ILNumericsDimSpec
Range specification along dimension #2.

d3

Type: ILNumericsDimSpec
Range specification along dimension #3.

Return Value

This method considers the given dimensional range specifiers to extract a subarray from this array. Both indexing styles: numpy and Matlab® indexing (ILNumericsV4) are supported. For such indexing features specific to one or the other style the current setting of ArrayStyle is considered. In ILNumericsV4 array style (default) the last given dimension specifier may refer to elements inside merged, trailing, unspecified dimensions of this array (and not only inside this dimension) in the same manner as the 'linear indexing' feature known from Matlab®, Octave, ILNumerics version 4 et al.

Due to the simplicity of the specifiers d0, ... the subarray creation is optimized to be fast and efficient, often without requiring new memory for copying elements. Note, that the array returned may use the same element storage as this array. Only when trying to modify either one of this array or the subarray a copy will be made.

The setting MinNumberOfArrayDimensions is respected for the array returned.
