选择工作区浏览器工具栏中的“Import Data”,选择待导入的文件,这里我们选择了一个文本文件,其内容为逗号分隔的数字,打开窗口如图13-3所示
let arrayData = [ '99ASD', '01A', '0134-A', '78134:TSX' ];let arrayNum = arrayData.map(s => parseInt(s, 10));console.log(arrayNum); 从多列的字符串中提取数字 这里有一种方法 如果你以文本或代码的形式发布数据,我将能够共享结果。 假设:除了、和之外,所有数字都在一起,并且没有用...
Cell array is a special data type of Matlab that can store different types of data. It integrates different types of related data into a single variable, making it easy and convenient to reference and process a large amount of related data. 构建元胞数组的方法有三种:直接赋值法、利用cell()函...
