Scilab - gui - 许多未知变量错误消息

问题描述 投票：0回答：1

仍然试图理解Scilab的逻辑，我为机械元素创建了一个小型计算工具。我遇到的主要问题是为计算代码找到正确的顺序（或语法）...我得到了很多“未知变量”错误，我不明白为什么？我试图改变函数定义的顺序，将变量声明为全局等，但似乎没有任何帮助。计算的代码不长也不复杂，但gui是使用guibuilder构建的，因此uicontrols定义可能比它们需要的时间长得多。有人可以帮助我使这段代码正常工作，因为我会通过这个例子学习和理解很多，虽然它包含多个“问题区”？在这里我做了什么：

G = 78500;

table_titles = ["" "Wire diameter" "Wp" "Tau alwd" "M alwd" "Angle alwd"];

f=figure('figure_position',[910,163],'figure_size',
[903,537],'auto_resize','on','background',[33],'figure_name','Graphic 
window number %d');

//Write your callback for  tab_param  here
   table_values = string([ wd Wp Talwd Malwd alphaalwd]);
   table_param = [table_titles; [table_values]];
endfunction

我希望代码根据输入滑块和弹出菜单的位置动态更新图形和参数表。

再一次，如果有人可以帮助我使这些代码工作，那将是非常有帮助的，因为我会得到很多关于使用scilab进行编程的问题的答案。

非常感谢你提前！

首先，您的代码不能直接执行，这是由换行符引起的。请在声明的每一行后添加...。这也提高了可读性。正如@luispauloml所提到的，您尝试使用存在于另一个函数内部的变量。例如，你试图到达table_param，这在tab_param_callback(handles)只是活着。要摆脱这个，你必须定义函数的输出：

function [table_values，table_param] = tab_param_callback（handles）

table_values = string（[wd Talwd Malwd alphaalwd]）;

table_param = [table_titles; [table_values]];

endfunction这样

现在你可以调用这个函数来获取变量：

字符串（tab_param_callback（句柄））

我纠正了这个案例并按照解释添加了点。对于其他变量，可以类似地完成。此外，我将函数定义移动到代码的开头。因为如果你的程序员在中间崩溃，编译器就没有机会阅读函数定义。

请在this file找到代码。

我希望这有帮助。祝好运！
