Problems solved by technology
[0004] However, this method can only input one item at a time, and cannot realize the combined input of multiple items, and needs to start and close the formula input method interface for many times during the input process. Switch regions back and forth between interfaces, such as entering a simple It is necessary to start the formula input method interface multiple times, therefore, it greatly affects the input efficiency

Embodiment Construction
[0012] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0013] figure 1 It is a flow chart of the formula input method of intelligent combination according to the present invention. refer to figure 1 , the formula input method includes the following steps:
[0014] In the first step, that is, step S100, the user inputs the coded character string of the formula. The interface for inputting coded character strings may adopt the formula input method interface disclosed in Chinese patent application No. 200810239672.2, which includes a character input area and a formula display area. The difference is that what the present invention inputs in the character input area is the encoded character string of the whole formula, rather than the name of an operator or symbol; what is displayed in the formula display area are several candidate formulas, rather than an operation pictures of signs or symbols. That is to say, the...

The invention provides an intelligently combined formula input method and an intelligently combined formula input system. The formula input method comprises the following steps of: inputting a coded character string of a formula; processing the input coded character string to acquire candidate formulas corresponding to the coded character string; and inserting the formula selected from the candidate formulas into an edited layout, wherein the processing step comprises the following steps of: segmenting the input coded character string and matching; integrating the matched content to acquire candidate items; typesetting coded data of the candidate items; and displaying candidate formulas on a candidate window for users to choose. The formula input system comprises an input unit, a coding, segmenting and matching unit, an integrating unit, a formula typesetting unit and a formula inserting unit. By the method and the system, the coded character string of the entire formula can be directly input in different application programs, and one-step display of the formula can be realized by segmenting, matching and integrating the coded character string, so the input efficiency of the formula is improved.
Description
technical field [0001] The invention relates to the technical field of printing and typesetting, in particular to an intelligently combined formula input method and system. Background technique [0002] Interactive formula typesetting software is a commonly used formula typesetting method, which is easy for users to learn and use. However, due to the need to constantly switch between the mouse and the keyboard, and the need to search for the required operators and symbols in a large number of operators and symbols in the toolbar template, the efficiency of entering formulas in the interactive formula typesetting software is low. [0003] In order to improve the efficiency of interactive formula typesetting, a method and system for quickly inputting formulas are disclosed in the Chinese patent application No. 200810239672.2 "A formula input method and system for interactive formula typesetting software". And the system enters the name of the operator or symbol in the charact...
