Programm to find adjoint of a matrix.

Question

the user can input a double dimension array and we have to display the matrix...as well as find its adjoint.
can anyone post any algorithm to do so...

Answer 1

Displaying the matrix should be easy with two nested for loops iterating over rows and columns, just include spaces for proper formatting.

If runtime is not a concern, you can write a simple recursive function to calculate the determinant and use that to get the input matrix's (n-1)x(n-1) minors, which are the entries of the classic adjoint.

There is a lot to be optimised here, as for example you are computing several minors more than once. If you want an optimal solution, you should probably pick up a book on computer algebra.
