Matrix<T>.fromData constructor
Creates a new N x M
matrix where rows
is N
and columns
is M
. The
matrix is filled with values from data
.
A MatrixException object is thrown if rows
*columns
is not equal
to data
length.
Implementation
Matrix.fromData({
required int rows,
required int columns,
required List<List<T>> data,
}) : rowCount = rows,
columnCount = columns,
_data = data.expand((e) => e).toList(growable: false) {
// Making sure the size is correct
if (_data.length != (rows * columns)) {
throw const MatrixException(
"The given sizes don't match the size of the data to be inserted.",
);
}
}
