Matlab median

Help Center Help Center. If A is a vector, then median A returns the median value of A. If A is matlab median nonempty matrix, then median A treats the columns of A as vectors and returns a row vector of median values. If A is an empty 0-by-0 matrix, matlab median, median A returns NaN.

If X is a matrix, then mad returns a row vector containing the mean or median absolute deviation of each column of X. If X is a multidimensional array, then mad operates along the first nonsingleton dimension of X. For example, if X is a 2-byby-4 array, then mad X,0,[1 2] returns a 1-byby-4 array. Each element of the output array is the mean absolute deviation of the elements on the corresponding page of X. Compare the robustness of the standard deviation, mean absolute deviation, and median absolute deviation in the presence of outliers.

For vectors x , nanmedian x is the median of the remaining elements, once NaN values are removed. For matrices X , nanmedian X is a row vector of column medians, once NaN values are removed. For multidimensional arrays X , nanmedian operates along the first nonsingleton dimension. Each element of vecdim represents a dimension of the input array X. The output y has length 1 in the specified operating dimensions. The other dimension lengths are the same for X and y. For example, if X is a 2-byby-4 array, then nanmedian X,[1 2] returns a 1-byby-4 array. Each element of the output array is the median of the elements on the corresponding page of X. Find the median of each page of X by specifying dimensions 1 and 2 as the operating dimensions. For example, ypage 1,1,1 is the median of the non- NaN elements in X :,:,1. Find the median of the elements in each X :,i,: slice by specifying dimensions 1 and 3 as the operating dimensions.

If dim is equal to 2, then mad X returns a column vector that contains the mean absolute deviation of each row in X. Output Arguments collapse all y — Matlab median or median absolute deviation scalar vector matrix multidimensional array, matlab median.

Before Ra, use commas to separate each name and value, and enclose Name in quotes. Missing value indicator, specified a scalar, vector, matrix, or multidimensional array of integers ranging from to Each element is a quality code to treat as missing data.

Example 2 — Subtracting the Mean. This example shows how to use MATLAB functions to calculate the maximum, mean, and standard deviation values for a by-3 matrix called count. To get the row numbers where the maximum data values occur in each data column, specify a second output parameter indx to return the row index. For example:. Here, the variable mx is a row vector that contains the maximum value in each of the three data columns. The variable indx contains the row indices in each column that correspond to the maximum values. To find the minimum value in the entire count matrix, by-3 matrix into a by-1 column vector by using the syntax count :.

Help Center Help Center. If A is a vector, then Q is a scalar or a vector with the same length as p. Q i contains the p i quantile. If A is a matrix, then Q is a row vector or a matrix, where the number of rows of Q is equal to length p. The i th row of Q contains the p i quantiles of each column of A. If A is a multidimensional array, then Q contains the quantiles computed along the first array dimension of size greater than 1. If A is a vector, then Q is a scalar or a vector with length n.

Therefore, Y2 is a 1-byby-2 array. Ignore missing values in A , and compute the median over fewer points. If X is a matrix, then mad returns a row vector containing the mean or median absolute deviation of each column of X. Tags median index. The dim input argument must be a compile-time constant. Start Hunting! Each element of the output array is the mean absolute deviation of the elements on the corresponding page of X. To update your code, change instances of the function name nanmedian to median. Off-Canvas Navigation Menu Toggle. Description Find the median values in an input or sequence of inputs. The other dimension lengths are the same for X and y.

Specify the 'Quality' name-value pair to indicate which data samples are considered missing. Search MathWorks. Find the median of each page of X by specifying dimensions 1 and 2 as the operating dimensions. If you do not specify the dim input argument, the working or operating dimension can be different in the generated code. This property applies only when you set the RunningMean property to false. There are no plans to remove nanmedian. For the even case, you already have a comment that almost correctly indicates what you are supposed to do - take the average of the two middle numbers whose indices would be. Help Center Help Center.
