Description copied from class: LongMatrix3D

Construct and returns a new empty matrix of the same dynamic type as the receiver, having the specified number of slices, rows and columns. For example, if the receiver is an instance of type DenseLongMatrix3D the new matrix must also be of type DenseLongMatrix3D, if the receiver is an instance of type SparseLongMatrix3D the new matrix must also be of type SparseLongMatrix3D, etc. In general, the new matrix should have internal parametrization as similar as possible.

Parameters:

slices - the number of slices the matrix shall have.

rows - the number of rows the matrix shall have.

columns - the number of columns the matrix shall have.

                     long value)

Description copied from class: LongMatrix3D

Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds.

Specified by:

vectorize in class LongMatrix3D

Returns:

a vector obtained by stacking the columns of each slice of the matrix on top of one another.

viewColumn

public LongMatrix2D viewColumn(int column)

Description copied from class: LongMatrix3D

Constructs and returns a new 2-dimensional slice view representing the slices and rows of the given column. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa.

To obtain a slice view on subranges, construct a sub-ranging view ( view().part(...)), then apply this method to the sub-range view. To obtain 1-dimensional views, apply this method, then apply another slice view (methods viewColumn, viewRow) on the intermediate 2-dimensional view. To obtain 1-dimensional views on subranges, apply both steps.

Description copied from class: LongMatrix3D

Constructs and returns a new selection view that is a matrix holding the indicated cells. There holds view.slices() == sliceIndexes.length, view.rows() == rowIndexes.length, view.columns() == columnIndexes.length and view.get(k,i,j) == this.get(sliceIndexes[k],rowIndexes[i],columnIndexes[j]) . Indexes can occur multiple times and can be in arbitrary order. For an example see LongMatrix2D.viewSelection(int[],int[]).

Parameters:

sliceIndexes - The slices of the cells that shall be visible in the new view. To indicate that all slices shall be visible, simply set this parameter to null.
