Hi,

I need to know when a number deflects to either side of a set up value(i.e. find the row where a value differs from 0+-0.5). I have tried this, but doesn't work:

deflection= find(RF>mean+standardeviation |RF<mean-standardeviation).

Thank you

Gonzalo

在 MATLAB Online 中打开

mean is a built-in function. It requires an argument, like mean(RF). Then it should work.

mu = mean(RF);
standarDeviation = std(RF);
deflectionAbove = RF > mu + standarDeviation % Logical vector
deflectionBelow = RF < mean - standarDeviation
deflection = deflectionAbove | deflectionBelow; % A logical vector
deflection = find(deflectionAbove | deflectionBelow); % A linear index vector
