在MATLAB中,Table的读写主要通过 数据读写方面,readtable和writetable函数使得硬盘文件与工作区间的交互变得简便,通过花括号{}、小括号()和圆点(.)的引用规则,Table支持灵活的数据提取和运算。例如,通过array2table、cell2table等函数,可以方便地将数组、Cell数组或结构体转换为Table类型。以2017至2018年上证指数数据为...
S=’a’ ’’indicates everything in the middle is a string Abs(s) means that each character has its corresponding ASCII value Char() represents a string Num2str(65) is expressed as the number 65 converted into ’65’ Length(str) is expressed as the length of the string [the length incl...
string scalar|character vector Name of the variable, script, function, folder, or class, specified as a string scalar or character vector. To specifynameas a relative path, it must fit one of these descriptions: A folder on the search path ...

readtext can read any text file. Any string (or even regexp) can be delimiting, default is a comma. Everything after (and including) a comment character, until the line end, is ignored. Quote characters may also be given, everything between them is treated as one item. There are ...

Syntactical errors will be reported in the QSPcc output with line and character where the error occurred. The following valid MATLAB constructs were not fully supported in QSPcc, and will be reported by QSPcc as errors. Negative exponentiation without parenthesis ...
a maximum of 32 characters is recognized. It is good practice to use a meaningful variable name. The variable name must not include spaces or hyphens. However, the underscore character is a useful replacement for a space. For example,test_runis acceptable;test runandtest-runare not. It is...
README This is a collection of MATLAB utilities developed by Kendrick Kay (kendrick@post.harvard.edu,http://kendrickkay.net). The philosophy of the code is to maximize power (i.e. the ability to perform many different things) and generality (i.e. the ability to re-use code for many di...
