MATLAB提供了table2array函数,可以直接将表转换为数组(在大多数情况下,数组就是矩阵)。如果表中的变量都是数值类型,那么转换后的数组就是一个矩阵。 matlab % 将表转换为数组(矩阵) myMatrix = table2array(myTable); 如果表中有非数值类型的变量(如字符串或分类变量),table2array函数会抛出错误。在这种情况...
To create (or convert to) a numeric matrix, all the elements must be numeric scalars (or numerical arrays of compatible dimensions for concatenation), which, by looking at the errors, is not the case with your data. You can either store hetergeneous data in a cell array or a table (or...
To convert a table to a matrix, use the “table2array” function. (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 i...
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...
