A necessary and sufficient condition for a dual matrix to have a {1}-dual generalized inverse is obtained. It is shown that a dual matrix always has a {1}-, {1,3}-, {1,4}-, {1,2,3}-, {1,2,4}-dual generalized inverse if and only if it has a {1}-dual generalized ...
12. Finding the characteristic polynomial of a Matrix ParserNG allows the quick evaluation of the characteristic polynomial of a square matrix; this polynomial can then be solved to find the eigenvalues, and hence the eigenvector of the Matrix. ...

Generally, the stationarity of the indicators is tested by an alternative hypothesis, but non-stationarity is suggested by the null hypothesis for the CADF and CIPS tests. Cointegration test Prior to the prediction of the long-run associations, the cointegration connection needs to be examined. Thu...
This code reads an image as a matrix and applies discrete cosine transform on it. Then, user needs to enter the quality factor he/she want for the compressed image. Predifined quantification matrix does the job of quantifying the image after dct. Now, we
The reason for using at-the-money options to calculate implied volatility (IV) is based on theoretical foundations (e.g. Hull & White, 1987; Jorion, 1995). At-the-money options should produce the smallest bias in the case of non-constant volatility. They are also considered to be the ...
I just couldn't understand how does augmented matrix deduce inverse of a matrix. I mean what is it in the row operation because of which we get the inverse of a matrix. I just don't want to learn the steps but to understand why it works. Thank you. Mathematics ...
There are 4 dependent variables: (a) agricultural per-FTE gross income, (b) non-agricultural per-FTE gross income, (c) off-farm agricultural per-FTE wage income, and (d) total per-FTE gross income. All of these dependent variables are transformed using the inverse hyperbolic sine ...
