WebSmoothing Involving Missing Values. Create a noisy vector containing NaN values, and smooth the data ignoring NaN values. A = [NaN randn (1,48) NaN randn (1,49) NaN]; B = smoothdata (A); Smooth the data including NaN values. The average in a window containing any NaN value is NaN. C = smoothdata (A, "includenan" ); WebThe resolution of a recording, ie, the ability to distinguish two objects that are spatially close together, varies directly with the frequency and inversely with the wavelength. High frequency, short wavelength ultrasound can separate objects that are less than 1 mm apart. Echocardiographic image resolution is generally 1 or 2 wavelengths.
