Read a multidimensional array and find its size in fortran programming

[srarunraj]

Dear friends,

I am a beginner to fortran programming. I wrote a code to find the inverse of a given matrix using Gauss elimination method. The code works for a matrix with given size. But in order to generalize the program (also in case if the matrix size is too large like in finite element method), i need to read any given array (from a text file or dat file) and find its size (row x column) rather than inputting those manually. Suggestions and helps are sincerely appreciated.

Thanks in advance

If you are using F95 onwards, have a look at ALLOCATE and allocatable arrays.
