Function Documentation

Matrix() [1/2]

template<int R = RowsAtCompileTime, int C = ColsAtCompileTime>

Matrix

(

std::initializer_list< double >

l

)

Constructs a vector or row matrix from a list of double values.

Precondition

The matrix is a vector or row vector (IsVectorOrRow<R,C>).

Parameters

l	Initializer list of double values to populate the matrix.

If the compile-time size is fixed to 1 (vector or row), the size is 1; otherwise, the size matches the initializer list size.

  : Matrix<double,R,C>(R == 1 ? 1 : l.size(), C == 1 ? 1 : l.size())
{
  assert_release(!std::empty(l));
  Index i = 0;
  for(const auto& li : l)
    (*this)[i++] = li;
}

Matrix() [2/2]

template<int R = RowsAtCompileTime, int C = ColsAtCompileTime>

Matrix ( int n, double values[] )

explicit

Constructs a vector or row matrix of size n from an array of double values.

Precondition

The matrix is a vector or row vector (IsVectorOrRow<R,C>).

Parameters

n	Number of elements (must be greater than 0).
values	Pointer to an array of double values to initialize the matrix.

  : Matrix<double,R,C>(R == 1 ? 1 : n, C == 1 ? 1 : n, values)
{
  assert_release(n > 0);
}
