Rank

rank - An m x n matrix that consists of rows m and columns n.- The rank of a matrix is the maximum number of linearly independent rows among m rows, or the maximum number of linearly independent columns among n columns. - If every row is linearly independent, then the rank of the matrix is m. - If all the columns are mutually independent, then the rank of the matrix is n. - When every row and ev..

Linearly independent, Linearly dependent

Linearly independent, Linearly dependent - Here are 7 vectors. Among these, vectors 2 and 3 can be created by multiplying scalars by vector 1 (pointing in the +y direction).- Vector 2 can be created by multiplying by a number greater than 1, and for vector 3, multiply by the same number as vector 2 and then multiply by -1 to change its direction.- Then, the shape produced by multiplying vector..

Jacobian determinant (Jacobian matrix) The Jacobian determinant is an indicator that tells how the area or volume of a coordinate system is transformed in a new arbitrary coordinate system. This is a local linear transformation that describes how the output vector changes in which direction and by how much (= sensitivity) when the input vector changes by only a very small amount. it can be used ..

Pixel The pictures on the computers are represented by dots. The fundamental unit of anything you see on any computer is the DOT, refers to them as pixels or PEL. So everything you see boils down to a dot or a collection of dots.Resolution For a given image, the number of dots horizontally versus the number of cots vertically.DPI (Dots Per Inch) When printing an image, pixels are converted into..

sed Stream Editor.Instead of opening a file manually in a visual text editor (like nano or vim), sed accepts an input stream (a text file or output piped from another command), processes it line-by-line according to specified rules, and outputs the result. For example,sed -n '1,100p' file -n : don't automatically print every line'1,100p' = print (p) lines 1 through 100-Rni -R Recursive-n Show..
