c are vectors of n size. I'm supposed to solve each system for x using "inv" and "\" functions and calculate the norm of the residual and norm of error. I know how to calculate the rest BUT I don't know how to
In linear algebra the norm is the function that assigns a positive length or size to a number. So for example the norm of negative six is six. It is usually denoted with double vertical lines x. Wiki User ∙12yago Copy Add Your Answer ...

That is the norm. It is implemented in MATLAB with norm() Without additional information, it is not clear which norm represents, i.e. the 2-norm, the 1-norm etc. 0 comentarios Iniciar sesión para comentar. Iniciar sesión para responder a esta pregunta. ...
It says "The default tolerance is MAX(SIZE(A)) * NORM(A) * EPS(class(A))." but what is coded is "tol = max(m,n) * eps(max(s));" on line 37 of revision 5.12.4.2. It should be max(m,n)*norm(A)*eps(max(s)) and I have corrected my local cop...
Open in MATLAB Online The l2 norm of a vector is the square root of the sum of the absolute values squared ThemeCopy X = randn(8,1); norm(X,2) The above is equal to ThemeCopy sqrt(sum(abs(X).^2)) 1 Comment mina on 2 Mar 2013 thank you so much Sign in to comment.Mo...
It's the order of the norm requested, in this case the "2-norm" which is the same thing ...
A more general subordinate matrix norm can be defined by taking different vector norms in the numerator and denominator: Some authors denote this norm by . A useful characterization of is given in the next result. Recall that denotes the dual of the vector norm . Theorem 1. For , Proof. ...
(try a value of 16). % thresh - Threshold of standard deviation to decide if a % block is a ridge region (Try a value 0.1 - 0.2) % % Returns: normim - Image where the ridge regions are renormalised to % have zero mean, unit standard deviation. % m...
( there is no error untill this part) after that I define another prob on DOMAIN for measure integration of current density norm .this is new variable that I want transfer to function of Matlab , but the problem is when I define this new prob I get the error that say: circular ...
