In table operations, we often encounter some more complex tasks, such as the summation of multiple conditional data, such as finding or referencing eligible data in another worksheet. These tasks can be accomplished using a combination of functions or functions, but for most people, such tasks are too complicated. In the WPS 2012 Table tool, but only "commonly used formula" can be completed, completely do not have to memorize those complex function combination, simple operation, worry and labor,
Excel functions are predefined, and perform calculations, analyses, and other special formulas for processing data tasks. Take the commonly used SUM function sum as an example, its syntax is "sum" (Number1,number2,...... )”。 where "SUM" is called a function name, a function has only one name, which determines the function and purpose of the function. The function name is followed by an opening parenthesis, followed by a comma-separated content called
A friend of mine, a math teacher, often needs to insert some mathematical formulas when editing a teaching slide. This will take you to the Equation Editor.
(If you want to edit complex formulas, you can do so in Word, and then copy them to PowerPoint.) Reference article: " with the EQ field complex mathematical formula can also easily do ", "Word input auxiliary plug-ins: Mathematical Equation Editor ")
The ability to insert formulas in WPS Office 2005 disappears, which makes math teachers very dissatisfied. However, WPS Text 2005 provides the "Insert Object" function, with it with professional mathematical formula software MathType, you can make WPS 2005 immediately have the function of inserting formulas!
First, download the MathType (download address) online, install and register.
After installing the

When using matplotlib drawing to add a formula to a picture, it is generally necessary to use the text or annotate function, combined with latex grammar ' $...$ '.For fractions, if you use \frac{}{} directly, the characters on the numerator denominator are small, as shown in the Green formula.To solve this problem, we need to use the \displaystyle, that is, using the ' $\displaystyle ... $ ', as shown in the Blue formula in the effect. However, the prerequisite for using this is that the system
have a little bit of formulas. To make such an effect, we only use junior high school .. Or the formula of physical knowledge, acceleration, and deceleration in high school. So it is indeed a small formula. The landlord is very fond of tossing some cool things. Although he may not be able to work at ordinary times, this pleasure is really fascinating. In addition, doing so can also enhance the Thinking Ability of programming.
Let's talk about theme.

During image processing, we generally use RGB space, but in some special cases, we also use other color spaces. This article mainly introduces some common color space concepts and conversion formulas.
The essence of color is a light wave. It exists because there are three entities: Light, observed object, and observer. The human eye uses color as a light wave formed by the observed object absorbing or reflecting different wavelengths. For example, whe
, and later encountered a data, dropped into this plane, see in the straight line which side, is which category.For example x+y-2=0 this line, we put the data (x, y) into, as long as the x+y-2>0 is a class, X+y-2And so on, there are three-dimensional, four-dimensional, n-dimension attributes of the classification, so the structure may not be a straight line, but the plane, super-plane.A three-dimensional function classification: x+y+z-2=0, this is a classification of the plane.Sometimes, the lin
distribution is expanded to the multi-dimensional Dirichlet distribution (Dirichlet distribution). The multi-dimensional distribution is the multi-dimensional distribution. The Dirichlet distribution function is as follows:
Multiple distribution functions are as follows:
K indicates k dimension. And are both constant coefficients. They do not look at the constant coefficients. The Dirichlet function has the same form as the multiple distribution functions. Therefore, the posterior distribution
