这将读取名为 'yourfile.csv' 的文件,并将数据转换为表格数据类型。然后,可以通过 `table2array` 函数将表格数据转换为矩阵:data_matrix = table2array(data);现在,data_matrix 包含了原始数据文件中的所有信息,以矩阵形式存在。总结来说,使用 MATLAB 将数据转换为矩阵主要依赖于定义矩阵、使用 c...
(A matrix is a 2-D array.) As an alternative, you can convert a table to an array by using the syntax “T{:,:}”, where “T” is the table. This syntax is the equivalent of “table2array”. All variables in the table must have sizes and data types that allow them to be h...
第一行求和结果为:|1|+|2|+|3|=6 第二行求和结果为:|4|+|5|+|6|=15 第三行求和结果为:|7|+|8|+|9|=24 里面最大的就是24,因此矩阵A的行和范数为24。
