% 创建一个变量名字符串var_name='my_variable';% 将变量值分配给变量名字符串assignin('base',var_name,42);% 使用assignin函数获取变量值value=assignin('base',var_name); 在这两种方法中,我们首先创建了一个变量名字符串my_variable,然后将变量值42分配给该变量名。最后,我们使用eval或assignin函数获...
I have variable name saved as a string in an array. I want to read the value of the variable into another array. Is there a function in matla which takes variable name as input and returns the value of that variable. 댓글 수: 1 Stephen23 2021년 6월 4일 https://www...

The code generator preserves your function name and comments. When possible, the code generator preserves your variable names. Note If a variable in your MATLAB code is set to a constant value, it does not appear as a variable in the generated C code. Instead, the generated C code contai...
