Required Methods§

Source

fn swap_entries( &mut self, row_0: impl TryInto<i64> + Display, col_0: impl TryInto<i64> + Display, row_1: impl TryInto<i64> + Display, col_1: impl TryInto<i64> + Display, ) -> Result<(), MathError>

Swaps two entries of the specified matrix.

Parameters:

  • row_0: specifies the row, in which the first entry is located
  • col_0: specifies the column, in which the first entry is located
  • row_1: specifies the row, in which the second entry is located
  • col_1: specifies the column, in which the second entry is located

Returns an empty Ok if the action could be performed successfully. Otherwise, a MathError is returned if one of the specified entries is not part of the matrix.

fn swap_rows( &mut self, row_0: impl TryInto<i64> + Display, row_1: impl TryInto<i64> + Display, ) -> Result<(), MathError>

Swaps two rows of the specified matrix.

Parameters:

  • row_0: specifies the first row which is swapped with the second one
  • row_1: specifies the second row which is swapped with the first one

Returns an empty Ok if the action could be performed successfully. Otherwise, a MathError is returned if one of the specified rows is not part of the matrix.

fn swap_columns( &mut self, col_0: impl TryInto<i64> + Display, col_1: impl TryInto<i64> + Display, ) -> Result<(), MathError>

Swaps two columns of the specified matrix.

Parameters:

  • col_0: specifies the first column which is swapped with the second one
  • col_1: specifies the second column which is swapped with the first one

Returns an empty Ok if the action could be performed successfully. Otherwise, a MathError is returned if one of the specified columns is not part of the matrix.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
