Calculate running mean values from a vector

## 1. SYNOPSIS

[b, good] = rmean a(n )

## 2. DESCRIPTION

Calculates the mean value for each set of n consecutive elements in a , moving along the elements of a. Vector a may have NaN values. Calling with n less than one, the function will return the input array with NaN values removed and the mask to these values.

## 3. PARAMETERS

a

  Vector of length N.

n

  Number of subsequent elements to take into account for calculating mean values.

## 4. RETURNS

b

  Vector of length `(N-2)`. Element `b(i)` is the mean value of the elements of a,starting from `a(i)`.

good optional

  Indexes to the elements of a that were used.
