Matrix<T>.vandermonde constructor
Matrix<T>.vandermonde (
- DataType<
T> dataType, - Vector<
T> data, - int columnCount, {
- MatrixFormat? format,
Returns a Vandermonde matrix, a matrix with the terms of a geometric progression in each row.
If format
is specified the resulting matrix is mutable, otherwise this
is a read-only view.
Implementation
factory Matrix.vandermonde(
DataType<T> dataType, Vector<T> data, int columnCount,
{MatrixFormat? format}) {
final pow = dataType.field.pow;
final exponents =
Vector<T>.generate(dataType, columnCount, (i) => dataType.cast(i));
return Matrix.generate(
dataType, data.count, columnCount, (r, c) => pow(data[r], exponents[c]),
format: format);
}
