Function 'range_calculator' has already been declared within this scope.

I have the following driver file named 'Program 6':

[x]=range_calculator(a,b)

and the following function file named 'range_calculator'

g=9.9;

function[x]=range_calculator(a,b)

x= ((b^2)*sin(2*a))/g;

end

and I keep getting the error message above. Should I change the file name?

Thanks,

It looks like you are trying to run a script that contains an internal function with the same name. You should not put any code before the first function definition if you intend a file to work as a function.

You may try removing the initialization of 'g' which is the first line in your function. In matlab, if you have code above the function definition inside your function file, it gets treated as a local function. So you will need to relocate your first line in the function to somewhere else or find another way to initialize 'g'.

Hope it Helps!
