Properties

cols

val cols: Int

The number of columns in the matrix.

data

val data: Array<DoubleArray>

rows

val rows: Int

The number of rows in the matrix.

Functions

columnMean

fun Matrix.columnMean(): Matrix

Calculates the mean of each column in the matrix and returns the result as a new single-row matrix.

copy

fun copy(): Matrix

get

operator fun get(row: Int, column: Int): Double

isSymmetric

fun isSymmetric(matrix: Matrix, tolerance: Double = 1.0E-10): Boolean

Checks if the given matrix is symmetric within a specified tolerance.

minus

operator fun Matrix.minus(other: Matrix): Matrix

operator fun Matrix.minus(other: SparseMatrix): Matrix

Extension function to subtract a SparseMatrix from a Matrix.

multiply

fun multiply(a: Matrix, b: Matrix): Matrix

Multiplies two matrices and returns the resulting matrix.

plus

operator fun Matrix.plus(other: SparseMatrix): Matrix

Extension function to add a Matrix to a SparseMatrix.

set

operator fun set(row: Int, column: Int, value: Double)

times

operator fun times(other: Matrix): Matrix

Multiplies this matrix with another matrix and returns the resulting matrix.

toSparseMatrix

fun Matrix.toSparseMatrix(): SparseMatrix

Extension function to convert a dense Matrix to a SparseMatrix.

transposed

fun transposed(): Matrix

Returns a new matrix that is the transpose of this matrix.
