Package org.ejml.data
Class CMatrixRMaj
java.lang.Object
org.ejml.data.CMatrixD1
org.ejml.data.CMatrixRMaj
- All Implemented Interfaces:
Serializable,CMatrix,Matrix,ReshapeMatrix
Dense matrix for complex numbers. Internally it stores its data in a single row-major array with the real
and imaginary components interlaces, in that order. The total number of elements in the array will be
numRows*numColumns*2.

CMatrixRMaj
public CMatrixRMaj(float[][] data) Creates a matrix with the values and shape defined by the 2D array 'data'. It is assumed that 'data' has a row-major formatting:
data[ row ][ column ]- Parameters:
data- 2D array representation of the matrix. Not modified.
