vnl_matrix_fixed< double , nrows, ncols > & vnl_matrix_fixed< double , nrows, ncols >::set_columns	(	unsigned	starting_column,
		vnl_matrix< double > const &	M
	)

inherited

Set columns to those in M, starting at starting_column, then return *this.

Definition at line 640 of file vnl_matrix_fixed.hxx.

◆ set_diagonal()

vnl_matrix_fixed< double , nrows, ncols > & vnl_matrix_fixed< double , nrows, ncols >::set_diagonal ( vnl_vector< double > const & diag )

inherited

Sets the diagonal elements of this matrix to the specified list of values.

Returning "*this" allows "chaining" two or more operations: see the reasoning (and the examples) in the documentation for method fill_diagonal().

Definition at line 177 of file vnl_matrix_fixed.hxx.

◆ set_identity()

vnl_matrix_fixed< double , nrows, ncols > & vnl_matrix_fixed< double , nrows, ncols >::set_identity ( )

inherited

Sets this matrix to an identity matrix, then returns "*this".

Returning "*this" allows e.g. passing an identity matrix as argument to a function f, without having to name the constructed matrix:

f(vnl_matrix_fixed<double,5,5>().set_identity());

Returning "*this" also allows "chaining" two or more operations: e.g., to set a 3x3 matrix to [3 0 0][0 2 0][0 0 1], one could say

M.set_identity().scale_row(0,3).scale_column(1,2);

If the matrix is not square, anyhow set main diagonal to 1, the rest to 0.
