Enumeration Type Documentation

enum ml_error_codes

Error codes for invalid matrix operations, stored in the public member variable ml_matrix::error. Enumeration values: ml_no_error = 0  No error reported. ml_bad_index = 1  Attempt to access an invalid row or column value. ml_size_mismatch = 2  The size of a matrix was incorrect for a given operation. ml_non_invertible_matrix = 3  Occurs when ml_matrix::inv() or inv() is called on a matrix that does not have an inverse. ml_bad_file_pointer = 4  Occurs when a matrix is constructed from an invalid file. ml_bad_range = 5  Occurs when a submatrixing call has row or column information which is invalid. ml_bad_operand = 6  Generally indicates an attempt to divide by zero. ml_bad_string_format = 7  Occurs when a matrix is constructed from an invalid string. ml_invalid_buffer = 8  Indicates a corrupted data buffer. ml_lapack_error = 9  LAPACK reported an error in a function call.

enum ml_comparison

Comparison operations for the ml_matrix::find() and ml_int_array::find() functions. Enumeration values: ml_equal_to  Compares for equality. ml_not_equal_to  Compares for inequality. ml_less_than  Compares for the first element greater than. ml_greater_than  Compares for the first element less than. ml_less_than_or_equal_to  Compares for the first element greater than or equal to. ml_greater_than_or_equal_to  Compares for the first element less than or equal to.
