PROBLEMS 1. Translate the following paragraphs into
8、Chinese.1.1 The MATLAB language includes an extremely large number of built-in functions to help us solve problems. This list of functions is much richer than the list of functions found in other languages such as Fortran or C+, and it includes device-independent plotting capabilities. A complete li
9、st of all MATLAB functions is available through MATLAB HELP, which can be accessed by clicking the HELP icon, or by typing helpdesk in the Command Window. 1.2 The fundamental unit of data in any MATLAB program is the array. An array is a collection of data values organized into rows and columns, and
10、 known by a single name. Individual data values within an array are accessed by including the name of the array followed by subscripts in parentheses that identify the row and column of the particular value. (ch2)2.
