Analyze histogramđ
Calculates statistical features from a histogram.
Inputsđ
histogram
: Histogram vector of size 1-by-N.
Outputsđ
first
: The index of the first non-zero value. -1 if all values are zeros, otherwise the value is on range 0âŚN-1.last
: The index of the last non-zero value. -1 if all values are zeros, otherwise the value is on range 0âŚN-1.range
: last - first + 1, or zero if the histogram is all zeros.sum
: Sum of all entries in the histogram.mean
: Mean of the dataset from which the histogram was calculated.weightedSum
: Sum of all entries in the histogram weighted by the index of each entry. Computed as sum * mean.minIndex
: The index of the minimum value. If there are many indices with the same value, this is the first one.maxIndex
: The index of the maximum value. If there are many indices with the same value, this is the first one.variance
: Variance of the dataset from which the histogram was calculated.stdDev
: Standard deviation of the dataset from which the histogram was calculated. Computed as square root of variance.stdMean
: Mean deviation of the dataset from which the histogram was calculated. Computed as average of absolute differences to the mean value.median
: Median of the dataset from which the histogram was calculated.skewness
: Skewness of the dataset from which the histogram was calculated.kurtosis
: Kurtosis of the dataset from which the histogram was calculated.localMinima
: An M-by-1 matrix of indices with local minima, including the global minimum.localMaxima
: An M-by-1 matrix of indices with local maxima, including the global maximum.
