% Values is a 401x1 double: 1 - 401
% In this example, I want to take the mean from Values(90) to Values(110).
% Specify Bounds
MAX = 90; %
MIN = 110;
idy = find(Values == MIN);
idz = find(Values == MAX);
Values = mean(Values(idy:idz));
This is simple & should be returning 1 number from Values after taking the mean, but it's resulting in a 1x7^6 double.
Is there a syntax error that I'm overlooking here?

code is simple enough. run the code line by line and see where is wrong.
The numerical value for MAX and MIN seems to be reversed. Is that correct?

I think, that you want to do this:
MAX = 110;
MIN = 90;
id = find( (MIN <= Values) & (Values <= MAX) )
Values = mean(Values(id))
I switched the MIN/MAX values

Ah, I see what I did now! The MAX value was lower than the MIN, so of course the computer's going to hate that. Thank you very much!
