   • What exactly does f: R->R or f:Z->R mean in discrete math?

     Top Answer

     Answered Dec 08, 2014 · 5 votes

     The notation f : A → B means "f is a function whose domain is A and whose codomain is B." Intuitively, this means that f takes as input an element of A and produces an output that's an element of B.

     In C, for example, this would be like the function prototype

     B f(A);-

     This just says that f takes in an A and returns a B, with the actual way that f performs the transformation not specified.

     Hope this helps!

   • What does ordered / unordered comparison mean?

     Top Answer

     Answered Oct 04, 2020 · 46 votes

     An ordered comparison checks if neither operand is NaN. Conversely, an unordered comparison checks if either operand is a NaN.

     This page gives some more information on this:

     • http://csapp.cs.cmu.edu/public/waside/waside-sse.pdf (section 5)

     The idea here is that comparisons with NaN are indeterminate. (can't decide the result) So an ordered/unordered comparison checks if this is (or isn't) the case.

     double a = 0.;double b = 0.;__m128d x = _mm_set1_pd(a / b); // NaN__m128d y = _mm_set1_pd(1.0); // 1.0__m128d z = _mm_set1_pd(1.0); // 1.0__m128d c0 = _mm_cmpord_pd(x,y); // NaN vs. 1.0__m128d c1 = _mm_cmpunord_pd(x,y); // NaN vs. 1.0__m128d c2 = _mm_cmpord_pd(y,z); // 1.0 vs. 1.0__m128d c3 = _mm_cmpunord_pd(y,z); // 1.0 vs. 1.0__m128d c4 = _mm_cmpord_pd(x,x); // NaN vs. NaN__m128d c5 = _mm_cmpunord_pd(x,x); // NaN vs. NaNcout << _mm_castpd_si128(c0).m128i_i64[0] << endl;cout << _mm_castpd_si128(c1).m128i_i64[0] << endl;cout << _mm_castpd_si128(c2).m128i_i64[0] << endl;cout << _mm_castpd_si128(c3).m128i_i64[0] << endl;cout << _mm_castpd_si128(c4).m128i_i64[0] << endl;cout << _mm_castpd_si128(c5).m128i_i64[0] << endl;

     Result:

     0-1-100-1

     Ordered return true if the operands are comparable (neither number is NaN):

     • Ordered comparison of 1.0 and 1.0 gives true.
     • Ordered comparison of NaN and 1.0 gives false.
     • Ordered comparison of NaN and NaN gives false.

     Unordered comparison is the exact opposite:

     • Unordered comparison of 1.0 and 1.0 gives false.
     • Unordered comparison of NaN and 1.0 gives true.
     • Unordered comparison of NaN and NaN gives true.

   • What does . mean in docker? Does it mean the current working directory of the image or the local machine?

     Top Answer

     Answered Mar 07, 2019 · 65 votes

     The . simply means "current working directory"

     docker build

     In the context of the docker build command, you are using it to signal that the build context for docker build is the current working directory. Like so:

     docker build -t mytag:0.1 .-

     Let's say that you have this structure:

     /home/me/myapp/├── Dockerfile├── theapp.py

     And you invoke the docker build command from /home/me/myapp - you will pass the current working directory as the build context. This means that docker will see the following filestructure when building:

     /├── Dockerfile├── theapp.py

     Dockerfile

     In the context of a Dockerfile, it means that same. Both inside and outside the image.

     Take this COPY instruction for example:

     COPY . /app-

     Here the . means the current working directory, where the docker build command is executed. This will be relative the to build context that is passed to the docker build command.

     For this COPY instruction:

     COPY theapp.py .-

     It means, take the file theapp.py and copy it to the working directory of the docker image that is being built. This directory can be set at build time with the WORKDIR instruction, so that:

     WORKDIR /appCOPY theapp.py .

     Would leave you with the file /app/theapp.py inside the resulting docker image.

     Finally, this COPY instruction:

     COPY . .-

     Means take everything from the working directory where the docker build command is issued, relative to the build context that is passed to it. And copy it to the current working directory of the docker image.

     'do' and 'od' is a "mirror" text block instruction that start with "do" and read software lines and end instruction with "od", because symbols "{" , "}" not is allowed,not exist, or means other type of instruction. some pseudo-code type with a limited set of instructions like architecture 'RIS' has compilators that read it.

     This means that your kernel is busy. If you want to interrupt/stop the execution, go to the menu Kernel and click Interrupt.If it doesn't work, click Restart. You need to go in a new cell and press Shift + Enter to see if it worked.

   How to represent ordered pairs using a mapping diagram?

   • We can represent ordered pairs using a mapping diagram, or relation diagram. These diagrams consist of parallel columns which individually represent the input of the function and the output of the function. Consider relation A from example 1. We can represent this relation in a mapping diagram as shown below.

   What is a group of ordered pairs in a table?

   • Hence, the information in the table can be represented as a group of ordered pairs, where the first value in each pair is the input and the second value is the output. Let’s begin by looking at the first column. The number of shots made is 0 and the total number of points is 0. The ordered pair is ( 0, 0).

   What is the first ordered pair?

   • The first input number is 6, and the arrow points to the output number 8. Hence, the first ordered pair is ( 6, 8). Similarly, the second input number, 10, has an arrow leading to the number 12, so the second ordered pair is ( 1 0, 1 2).

   5 days ago · Function. A relation is a set of ordered pairs, where each pair consists of two elements, establishing a relationship between them. A function is a special type of relation where each input value (domain) is associated with exactly one output value (range). A single input can be related to multiple outputs.
