template<matrix_order RO, matrix_style RS, typename T , matrix_order PO1, matrix_style PS1, matrix_order PO2, matrix_style PS2, typename S > Matrix<T,RO,RS> scythe::atan2 ( const Matrix< T, PO1, PS1 > &  A, const Matrix< S, PO2, PS2 > &  B  ) Calculate the angle whose tangent is y/x. This function calculates the angle whose tangent is y/x, given two matrices A and B (where y is the ith element of A, and x is the jth element of matrix B). Parameters: A The matrix of y values B The matrix of x values See also: tan() tanh() sin() sinh() cos() cosh() acos() acosh() asin() asinh() atan() atanh()
