A diagonal matrix is a matrix with all zero on the off diagonal elements. When multiplying a matrix with a diagonal matrix , when the diagonal element is post-multiplying the matrix. The result is the same as the matrix but with the columns weighted each by the corresponding element inContinue Reading
Rank is a single non-negative integer number that represents the number of dimensions of information in the matrix, and is a property of the whole matrix not specifically columns or rows. The dimensions of information is the number of linear independent rows or columns in the matrix. The maximum rankContinue Reading
The Euclidean algorithm is based on the principle that the greatest common divisor (GCD) of two numbers does not change if the larger number is replaced by its difference with the smaller number. This is repeated with successive smaller pairs of numbers until they both are equal, which in thatContinue Reading
