Also have a look at FORTRAN syntax package MinimalFortran if you use Sublime text.

This is a collection of useful matrix operators and other mathematical functions. Many more functions will be added as and when I will feel the need of it.

1. Determinant of a matrix [function]

• SYNTAX: value = det(a,tole)
• RESULT: Determinant of matrix 'a' is stored in 'value' with tolerance of 10^(-tole)
• DESCRIPTION: LU decomposition is used for computation (DoLittle Algorithm)
• REFERENCE: Vismor DoLittle Algorithm
• CAUTION: Input only square matrices

2. Printing a 2-D matrix in rows and columns [subroutine]

• SYNTAX: call printmat2d(a)
• RESULT: Matrix 'a' is printed in rows and columns

3. Inverse of a matrix [function]

• SYNTAX: inv(a,tole)

• RESULT: Returns inverse of matrix 'a' with tolerance of 10^(-tole)

• DESCRIPTION: Utilizes LU decomposition and Row operations on U & L

• CAUTION: Inverse of a singular matrix cannot be evaluated

• Remember to use mathlib.f90 in the main program
