Matrix Calculus is the best current application for mathematical operations involving numbers, matrices and multi-dimensional matrices;

it’s able to perform all standard mathematical calculations on numbers, vectors (matrices of size 1) and matrices from 2 to 5 dimensions.

The only limits are the following:

- Dimensions of a matrix from 1 to 5

- Maximum total length of a matrix less than 3200

- Maximum length of a matrix dimension = 50

The possible operations are the standard of mathematics and the following matrix operations:

* = product matrix

/ = division of two matrices, or product of the inverse matrix

^ = power of a matrix (only with integers)

+ = sum matrix

- = difference matrix

Det = Determinant

Tra = matrix transpose

Inv = matrix inverse

Adj = adjoint matrix

tr(A) = trace of matrix A

Unit = matrix unit

Rank = matrix rank

Erf = error function erf

REF = matrix in Row Echelon Form (system solution)

The following matrix operations are operative only with the Pro version:

Inv+ = Moore - Penrose pseudo inverse

Eigen = matrix eigenvalues

Evect = matrix eigenvectors

Vsing = matrix singular values S

Uvect = left vector singular matrix U

Vvect = right vector singular matrix V

Dsum = matrix direct sum

Outer = outer product

L(L*L’) = Lower triangolar matrix L so that A = L*L’

Q(Q*R) = Left matrix Q so that A = Q*R

R(Q*R) = Wright matrix R so thar A = Q*R

Jordan = Jordan matrix J

||A|| = Frobenius norm

e^A = exponential of matrix A

√ A = square root matrix

If the matrix allows, it is also possible to calculate a matrix function, where the function is one of those of the calculator, for example (A = matrix):

lne (A), log (A), sin (A) cos (A), tan (A), sinh (A), arcsin (A), arctanh (A)
