validateEqualLengthVectors static method

void validateEqualLengthVectors(List<List<double>> data)

Ensures all vectors in a 2D dataset have the same length.

Example input: [ 1.0, 2.0, 2.5, 3.1, 4.2, 5.0 ]

Implementation

static void validateEqualLengthVectors(List<List<double>> data) {
  if (data.isEmpty) return;

  final int length = data[0].length;
  for (var vector in data) {
    if (vector.length != length) {
      throw ArgumentError('All vectors must have the same number of elements.');
    }
  }
}
