Details:

This is basically the same issue as bug #50007.

Matlab provides optional string arguments to some core functions that allow
you to omit NaN values. Please excuse the cut & paste job... the result of a
search for "nanflag" in the matlab online documentation.

I'm fairly sure most of these derive from the fundamental sum, median, min,
max functions so the list is almost certainly redundant.



median - Median value of array
This MATLAB function returns the median value of A.
        
min - Smallest elements in array
This MATLAB function returns the smallest elements of A.
        
max - Largest elements in array
This MATLAB function returns the largest elements of A.
        
sum - Sum of array elements
This MATLAB function returns the sum of the elements of A along the first
array dimension whose size does not equal 1.
        
mean - Average or mean value of array
This MATLAB function returns the mean of the elements of A along the first
array dimension whose size does not equal 1.

std - Standard deviation
This MATLAB function returns the standard deviation of the elements of A along
the first array dimension whose size does not equal 1.
        
bounds - Smallest and largest elements
This MATLAB function returns the smallest element S and largest element L of
an array.
        
cov - Covariance
This MATLAB function returns the covariance.
        
var - Variance
This MATLAB function returns the variance of the elements of A along the first
array dimension whose size does not equal 1.
        
prod - Product of array elements
This MATLAB function returns the product of the array elements of A.

cummin - Cumulative minimum
This MATLAB function returns the cumulative minimum elements of A.
        
cummax - Cumulative maximum
This MATLAB function returns the cumulative maximum elements of A.
        
cumprod - Cumulative product
This MATLAB function returns the cumulative product of A starting at the
beginning of the first array dimension in A whose size does not equal 1.
        
cumsum - Cumulative sum
This MATLAB function returns the cumulative sum of A starting at the beginning
of the first array dimension in A whose size does not equal 1.
        
movmean - Moving mean
This MATLAB function returns an array of local k-point mean values, where each
mean is calculated over a sliding window of length k across neighboring
elements of A.

movmax - Moving maximum
This MATLAB function returns an array of local k-point maximum values, where
each maximum is calculated over a sliding window of length k across
neighboring elements of A.

movmedian - Moving median
This MATLAB function returns an array of local k-point median values, where
each median is calculated over a sliding window of length k across neighboring
elements of A.
        
movmin - Moving minimum
This MATLAB function returns an array of local k-point centered minimum
values, where each minimum is calculated over a sliding window of length k
across neighboring elements of A.
        
movsum - Moving sum
This MATLAB function returns an array of local k-point sums, where each sum is
calculated over a sliding window of length k across neighboring elements of
A.
        
medfilt1 - 1-D median filtering
This MATLAB function applies a third-order one-dimensional median filter to
the input vector, x.

movstd - Moving standard deviation
This MATLAB function returns an array of local k-point standard deviation
values.
        
movvar - Moving variance
This MATLAB function returns an array of local k-point variance values, where
each variance is calculated over a sliding window of length k across
neighboring elements of A.
        
movprod - Moving product
This MATLAB function returns an array of local k-point products, where each
product is calculated over a sliding window of length k across neighboring
elements of A.
        
movmad - Moving median absolute deviation
This MATLAB function returns an array of local k-point median absolute
deviations (MADs), where each MAD is calculated over a sliding window of
length k across neighboring elements of A.
        
smoothdata - Smooth noisy data
This MATLAB function returns a moving average of the elements of a vector
using a fixed window length that is determined heuristically.
