If x is a row or column vector, y is a realvalued scalar. Median value of array matlab median mathworks deutschland.
The matrix that i will be testing will always be odd, so there is no need to be. For example, if x is an nbym matrix with n 1, then y is a 1bym row vector containing the rms levels of the columns of x. Average or mean value of array matlab mean mathworks. How to calculate weighted average in an excel pivot table. The expression can be further edited in the set values dialog which provides a lower panel to execute before formula scripts for preprocessing data. Set this flag to true or 1 to indicate that fun is a function that accepts a scalar input and returns a vector, matrix, or nd array output the default value of false indicates that fun is a function that accepts a vector input and returns a vector output. If x is a vector, then mad returns the mean or median absolute deviation of the values in x. For example, if a is a matrix, then mean a,2 is a column vector containing the mean of each row.
