In MATLAB, when an operation is manually terminated by the user via actions like Ctrl+C, the command line will print a prompt message that includes the relevant line number in legacy versions (e.g., R2016); however, this line number is omitted from the prompt in newer releases such as R2022.

function custom_interrupt_info()

disp('程序启动，按下Ctrl+C可中止并显示详细行号...');

iteration_num = 100000; % 模拟耗时迭代

try

% #################### 你的核心业务代码 ####################

for i = 1:iteration_num

disp(['当前执行第 ', num2str(i), ' 次迭代']);

pause(0.03); % 模拟耗时操作，方便触发Ctrl+C

temp_result = i * 2; % 示例计算逻辑

end

% ##########################################################

finally

% 关键：无论是否中止，都获取并输出完整中止信息（含行号）

disp('=====================================================');

disp('==================== 中止详细信息 ====================');

stack_info = dbstack; % 提取堆栈信息（核心：获取行号）

if ~isempty(stack_info)

% 输出自定义详细信息，包含行号、文件、函数

disp(['✅ 中止文件：', stack_info(1).file]);

disp(['✅ 中止行号：', num2str(stack_info(1).line)]);

disp(['✅ 所在脚本/函数：', stack_info(1).name]);

else

disp('✅ 程序正常结束，无中止操作');

end

disp('=====================================================');

end

how to set

display line number as 2016

[John D'Errico]

Running in R2025b, I tried this basic test:

function intertestfun
i = 1;
while i
end

Now if I run that little test case, I get the behavior you want when I use control+C to terminate the infinite loop.

intertestfun
Operation terminated by user during intertestfun (line 6)

So then I tried your code, and I still get the desired behavior.

Operation terminated by user during custom_interrupt_info (line 9)

Hi,@新杰

通过你提供的下面代码，我在R2024a,R2025a,R2026a三个近期版本均未发现你所说的问题，建议你更新到较新版本！

Based on the code you provided, I haven't encountered the problem you mentioned in the three recent versions R2024a, R2025a, and R2026a. I suggest you update to a newer version!

function custom_interrupt_info()
disp('程序启动，按下Ctrl+C可中止并显示详细行号...');
iteration_num = 100000; % 模拟耗时迭代

try
    % #################### 你的核心业务代码 ####################
    for i = 1:iteration_num
        disp(['当前执行第 ', num2str(i), ' 次迭代']);
        pause(0.03); % 模拟耗时操作，方便触发Ctrl+C
        temp_result = i * 2; % 示例计算逻辑
    end
    % ##########################################################
    finally
    % 关键：无论是否中止，都获取并输出完整中止信息（含行号）
    disp('=====================================================');
    disp('==================== 中止详细信息 ====================');
    stack_info = dbstack; % 提取堆栈信息（核心：获取行号）

    if ~isempty(stack_info)
        % 输出自定义详细信息，包含行号、文件、函数
        disp(['✅ 中止文件：', stack_info(1).file]);
        disp(['✅ 中止行号：', num2str(stack_info(1).line)]);
        disp(['✅ 所在脚本/函数：', stack_info(1).name]);
    else
        disp('✅ 程序正常结束，无中止操作');
    end
    disp('=====================================================');
end
end
