About the averaging_filter Function. The averaging_filter.m function acts as an averaging filter on the input signal; it takes an input vector of values and computes an average for each value in the vector. The output vector is the same size and shape as the input vector. type averaging_filter The dsp.MovingAverage System object™ computes the moving average of the input signal along each channel, independently over time. The object uses either the sliding window method or the exponential weighting method to compute the moving average. In the sliding window method, a window of specified length is moved over the data, sample by sample, and the average is computed over the data in the window. In the exponential weighting method, the object multiplies the data samples with a set of. Matlab function: mean - Average or mean value of array.

Averaging Images Over Time. View MATLAB Command. This example shows how to average images acquired over time. For some advanced applications, the acquisition process may require that images be processed as they are acquired, while your processing results are recorded to disk I would like to average every 3 values of an vector in Matlab, and then assign the average to the elements that produced it. Examples: x= [1:12]; y=%The averaging operation; After the operation, y= [2 2 2 5 5 5 8 8 8 11 11 11] Therefore the produced vector is the same size, and the jumping average every 3 values replaces the values that were used. https://www.mathworks.com/matlabcentral/answers/426506-averaging-values-within-bins#answer_343859.
