For smaller matrices (2x2, 3x3), doing it directly (by calculating a lot of determinants) is ok. For larger matrices, Gauss-Jordan elimination will be faster.<br />

For matrices with special properties, more specific algorithms (faster) exist.

Thanks unassassinable !<br />
but its really very large code. and, which method it is based on ?<br />
<br />
Thanks Infinity08 ! <br />
yes, i read Guass Jordon method, long ago. may i have any lnformation / link on it.<br />
<br />
Thanks again.<br />

which is the easiest way to invert a matrix in  C?


Program to Inverse a Matrix

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
