global variable not always global
显示 更早的评论
I am relatively new to Matlab. Sometimes when I declare a variable as global its value does not carry to all functions. I list the variable in the 'global' section at the top of each function. I see the variable in the global section of each function, but the code does not see it that way. When I highlight that variable all other instances of it are highlighted in the function. But the same variable is not highlighted in other functions. It is not incorrect spelling or capitalization - I have copied and pasted. I know I have sometimes I declared a variable global more than once in a function and then deleted the duplicates.
My question is once I've made this mess how do I correct it so the code works.
Thanks for your help with the elementary question.

It is difficult to diagnose this situation without seeing any code. Are you able to provide an example that illustrates the problem you are having?

It will be better if you can share the section of your code.

I would not expect the MATLAB editor to highlight copies of the variable in other functions.
