Four valued logic - Four valued logic is used to model signal values in digital circuits: the four values are Z, X and the boolean values 1 and 0. Z stands for high impedance or open circuit, while X stands for 'unknown'. There is also a 9-valued logic standard by the IEEE called IEEE 1164. There are other types..
Four exponentials conjecture - In mathematics, specifically transcendence theory, the four exponentials conjecture is a conjecture which, given the right conditions on the exponents, would guarantee the transcendence of at least one of four exponentials. If x 1, x 2 and y 1, y 2 are two pairs of complex numbers, with..

Matrices and Determinants..Definition of Matrix
It is a rectangular array of numbers, arranged in rows and columns. The number of rows (say m) and the number of columns (say n) determine the order of the matrix. It is written as m x n (to be read as m by n). The plural of matrix is matrices. Matrix is usu..

  how to find the determinants of 4x4 matrix?the inverse of a 2X2 square matrix in finding the inverse of a 3X3 square matrix. Once you find the inverse matrix, you should be able to multiply the original matrix by the inverse matrix and get the identity matrix. The identification of the inverse of 3X3 square matrices begins with finding the determinant (or scalar) of the full 3X3 matrix followed by finding the determinant of subcomponents of that 3X3 matrix (finding the minor determinants). Once all determinants are found, ...
Question : Is there any program on the net that calculates the eigenvectors (and eigenvalues) of a 4X4 (and higher) matrix? I do not want to calculate it by hand!
Or at least a more convenient method...
Thanks from Greece.
