Class matrix_view_table_transpose (o2scl)

O2scl : Class List

template<class vec_t = std::vector<double>, class fp_t = double>
class matrix_view_table_transpose : public o2scl::matrix_view

View a o2scl::table object as a transposed matrix.

When connected to a table, the size1() function returns the number of columns which were originally specified in either the constructor or the set() function, and the size2() function returns number of lines in the table.

Note

This stores a pointer to the table and the user must ensure that the pointer is valid with the matrix view is accessed.

Public Functions
