One needs to show that if $\mathrm{rank}(B)=k$ , then $\|A-B\|_2\geq\|A-A_k\|_2$ . This can be done as follows. Since $\mathrm{rank}(B)=k$ , $\dim\mathcal{N}(B)=n-k$ and from $$\dim\mathcal{N}(B)+\dim\mathcal{R}(V_{k+1})=n-k+k+1=n+1$$ (where $V_{k+1}=[v_1,\ldots,v_{k+1}]$ is the matrix of right singular vectors associa...

It has taken a few days, but I believe I can at last answer my own question. The strategy is to show that, for every combination of the $(n,k)$ lock, there is a combination of the $(k-1,n+1)$ lock that needs the same number of turns to unlock. The argument begins by grouping lock combinations into equivalence classes i...

I believe theory developed in two stages here.

An analogue is perhaps Weierstrass, who discussed the convergence of s...

First of all, an I-V curve does not make any sense for a capacitor. This is because a capacitor follows the following equation:$$i = C \frac{dV}{dt}$$ Note that the current depends on the rate of change of voltage. So you can have the same current at two different voltages, if the rate of change is the same. The reason...

With "scripts" you can always pass a multi-line/command script to the server for processing to get what you want done. This question is then answered with normal programming techniques using variables, if/then statements, etc: t = g.V().has('person','name','bill')t.hasNext() ? t.next() : g.addV('person').property('name...

Below is a question asked on the forum Stackoverflow.com. Provide a good and informational response to it like a helpful human would. Question: Whenever I try to import Metal in my Swift file or a playground, Xcode says "No such module 'Metal'". Is this a Beta 1 bug? Now provide the response and nothing else.
This is a platform issue, not a Swift issue. If you manually inspect the platform SDKs inside Xcode, you'll see that the Metal.framework only exists in the iOS8 SDK. That means you can only link to the framework when your code is going to run on an actual iOS device, and since playgrounds don't run on the device, there...

Question: Using tomcat, how do I get a request for http://www.mydomain.example to redirect to http://www.mydomain.example/somethingelse/index.jsp ? I haven't even managed to get an ind...
You can do this: If your tomcat installation is default and you have not done any changes, then the default war will be ROOT.war . Thus whenever you will call http://yourserver.example.com/ , it will call the index.html or index.jsp of your default WAR file. Make the following changes in your webapp/ROOT folder for red...

Introduce the following variables (Leibovici style$^*$) $$u=2(3x+4y)\,\,\text{ and } \,\, v=3(4x-3y).$$ Then we get a circle of radius $30$ in the $u,v$ coordinate system:$$u^2+v^2=900.$$ In this coordinate system the point from which we measure the distance of the points on the circle is $$(30, 0).$$ So, the closest p...

First of all, you need to realize that ~ is the bitwise flip operator, which is not the same as the negate operator - . ~ does only do the bitwise flipping, but the negate operator - does bitwise flipping and add one (for integers). As you've explained, if yo want to go from a postive number n to -n using the two compl...

I wouldn't call it "deep", but here's an intuitive reasoning. Intersections have elements that come from both sets, so they have the properties of both sets. If, for each of the component sets, there is some element(s) guaranteed to exist within that set, then such element(s) must necessarily exist in the intersection....

2.51 * 100 = 250.999999999997 The int() function simply truncates the number at the decimal point, giving 250. Use int(round(2.51*100)) to get 251 as an integer. In general, floating point numbers cannot be represented exactly. One should therefore be careful of round-off errors. As mentioned, this is not a Python-spec...

You can't depend on the file having a BOM. UTF-8 doesn't require it. And non-Unicode encodings don't even have a BOM. There are, however, other ways to detect the encoding. UTF-32 BOM is 00 00 FE FF (for BE) or FF FE 00 00 (for LE). But UTF-32 is easy to detect even without a BOM. This is because the Unicode code p...
