- TL;DR Summary
- Some Google-searching has led me to believe that Fortran does not have a built-in function for calculating the determinant of a given matrix. I've found only source codes and external libraries that have been written for this purpose. Does Fortran just not have any functions that calculate determinants directly? If it does not, then why not?

Fortran:

```
program main
! use ! some library that defines the function to calculate the determinant of a given matrix
implicit none
real,dimension(2,2)::A
real::det_val
A(1,1)=1
A(2,2)=1
A(2,1)=0
A(1,2)=0
! det_val=det(A)
print *,det_val ! Should print 1.
end program main
```
