I am investigating why China has inflation, and we Indian students are trying to understand it. The China data we got, and inflation perform in China. So we can take precaution for our county in India too.
I am getting this error and I am not aware that why I am getting such an error. Can anyone guide me please ?![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/329957/image.jpeg)

Input.T_11 is defined in Main.m. Main.m calls Func_Task_11.m but does not pass Input to Func_Task_11() so when you get inside Func_Task_11, the Input variable is not in scope. Remember each function has it's own workspace separate from the others. If you want input in Func_Task_11(), you need to pass it in
In Main.m:
Func_Task_11(Input);
In Func_Task_11.m
function Func_Task_11(Input)
as the first line.
Also, do not use eps as a variable name - it's a built-in function.

The error message says that there is no field "T11" in (struct-) variable "Input". Set a breakpoint on the respective line and check.
It looks like you edited the script "Func_Task_11" after the error message was thrown, as line 29 in your screenshot is empty. If you didn't edit inbetween, "Func_Task_11.m" might be shadowed by another script of the same name on the matlab-path.
