TXT Files¶

namespace mocca

Enable (1) or disable (0, default) the support for the Parallel HDF5 library. Requires a MPI library (e.g., OpenMPI, MPICH, etc.).

namespace io

Functions

template<typename T> Matrix<T> read_mat_txt(std::string path)¶

Reads and parses a TXT file and stores the contents in a Matrix. The TXT file must have the following format:

nrows ncols
(0, 0) (0, 1) ... (0, ncols - 1)
(1, 0) (1, 1) ... (1, ncols - 1)
...
(nrows - 1, 0) (nrows - 1, 1) ... (nrows - 1, ncols - 1)

where (i, j) is a matrix entry in the i-th row and j-th column.

Complexity: Linear with the file size.

Parameters:

Returns:

a Matrix with the contents of the file if mat is not specified. void, otherwise.

template<typename T, internal::TypeLayout L> void read_vec_txt(std::string path, Vector<T, L> &vec)¶

template<typename T> Vector<T> read_vec_txt(std::string path)¶

Reads and parses a TXT file and stores the contents in a Vector. The TXT file must have the following format:

size
(0)
(1)
...
(size - 1)

where (i) is a vector entry in the i-th position.

Complexity: Linear with the file size.

Parameters:

Returns:

a Vector with the contents of the file if vec is not specified. void, otherwise.

template<typename T, internal::TypeLayout L> void write_txt(const Vector<T, L> &vec, std::string path)¶

Writes the content of a Vector into a TXT file with the following format:

size
(0)
(1)
...
(size - 1)

where (i) is a vector entry in the i-th position.

Complexity: Linear in vec.size().

Parameters:

template<typename T> void write_txt(const Matrix<T> &mat, std::string path)¶

Write the content of a Matrix into a TXT file with the following format:

nrows ncols
(0, 0) (0, 1) ... (0, ncols - 1)
(1, 0) (1, 1) ... (1, ncols - 1)
...
(nrows - 1, 0) (nrows - 1, 1) ... (nrows - 1, ncols - 1)

where (i, j) is a matrix entry in the i-th row and j-th column.

Complexity: Linear in mat.size().

Parameters:
