Finding a solution to a set of linear algebraic equations in Mathcad with Kramer method
In Mathcad Kramer method is in use for finding a solution to a set n of linear algebraic equations with n unknown variables, equation looks like A*x =b, solution based on precomputation of system determinants on condition that determinant of matrix А has nonzero value. Method is based on Kramer formulas, which look like , where is the determinant of the matrix, which we got after we changed i-matrix column, i.e. coefficient column which determines the unknown variable Xi, into vector of absolute terms b in matrix А of the system. The example of a solution to a set of linear algebraic equations in Mathcad with Kramer method is shown in the programme listing.
