I, along with my wife was interviewed in March 2024 for an IR-5 Green card visa, my wife was issued a visa, and I was given a 221-G white form, asking me to provide some more information about my travels to different countries, as I worked on Ships. I submitted the required information, and after that, they asked 2 times to provide some more information, which I did lately in mid-Aug 2024. I haven't heard back from the Embassy for the last 45 days. Kindly let me know because of your experience, how long will it take to decide about my Administrative processing? I was previously issued U.S. visas 3 times in the past
Sir , I have a question where the absolute value of the entries of the leading diagonal is same as the sum of other entries(i.e |a11| = |a12| + |a13|). according to what u taught this matrix is not strictly diagonally dominant..but for this matrix the Gauss Siedel method converges according to the forbenious norm method, Would seek for some clarification..Thank u for this vedio
"Strictly diagonally dominant matrix" is the sufficient (not necessary) condition for the solution to converge. Orginally the given system solution was not convergent. After modification through elementary row operations, the coefficient matrix of the equivalent system becomes strictly diagonally dominant which sufficiently proves the convergence of the solution. Feel free to write if you need further explanation.
