(echelon matrix)
Defined at lib/math/matrix.lisp:128:2
Reduce the given MATRIX to row echelon form.
Example:
> (echelon (matrix 3 2
. 1 2 3
. 4 5 6))
out = [1 1.25 1.5 // 0 1 2]
(height matrix)
Defined at lib/math/matrix.lisp:6:2
The height of this matrix.
(identity dim)
Defined at lib/math/matrix.lisp:32:2
Create the identity matrix with the given DIM.
Example:
> (identity 2)
out = [1 0 // 0 1]
(invert matrix)
Defined at lib/math/matrix.lisp:206:2
Invert the provided MATRIX.
Example:
> (invert (matrix 2 2
. 1 2
. 3 4))
out = [-2 1 // 1.5 -0.5]
(matrix width height &items)
Defined at lib/math/matrix.lisp:13:2
Create a new matrix with the given WIDTH and HEIGHT.
Example:
> (matrix 2 2
. 1 2
. 3 4)
out = [1 2 // 3 4]
(matrix-item matrix y x)
Defined at lib/math/matrix.lisp:48:2
Get the item in the provided MATRIX at Y X.
Example:
> (define m (matrix 2 2
. 1 2
. 3 4))
> (matrix-item m 2 1)
out = 3
(reduced-echelon matrix)
Defined at lib/math/matrix.lisp:179:2
Reduce the given MATRIX to reduced row echelon form.
Example:
> (echelon (matrix 3 2
. 1 2 3
. 4 5 6))
out = [1 1.25 1.5 // 0 1 2]
(width matrix)
Defined at lib/math/matrix.lisp:6:2
The width of this matrix.
