it's pretty confusing, but when you made str you made it as a double array. str = []; class(str) ans ='double' So when you assign something to it it's getting cast to string. You could've done this: arr = [1,2,3,4,5]; ...
When the input argument is a string array, thedoublefunction treats each element as the representation of a floating-point value. However, when the input is a character array,doubleinstead converts each character to a number representing its Unicode® value. As an alternative, use thestr2double...
double 是浮点数的意思，array是数组的意思，double array在matlab中是指浮点型数据数组 意为双精度浮点型数组。在matlab中的double类型：matlab默认的数据类型是double(64位) 。 double是双精度浮点数，保留16位有效数字 。 双精度到底是几位，与你的系统有关的，如果你的系统是32位的，那么一般双...

直接用指令table2array就能把table改成double 首先,确保你的表格数据源没有包含任何非数值数据。你可以使用table函数加载数据后,检查数据类型,例如:[代码示例]:tableVar = readtable('yourfile.csv');isnumeric(tableVar) % 检查是否全是数值类型 如果检查结果显示数据中包含非数值类型,你可以考虑进行数据清理,例如:...

Str2num converts strings to numeric format, but the question was the other way around. The correct and best answer should be https://se.mathworks.com/matlabcentral/answers/286544-how-i-could-convert-matrix-double-to-cell-array-of-string#answer_331847 Walter Roberson on 14 Apr 2021...
Using double to convert a char array produces an array of the corresponding Unicode® values. Text in strings does not convert in this way. For example: Not RecommendedRecommended x = str2double('13') x = 13 x = double(string('13')) x = 13...
