If A is a 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, median A returns NaN. If A is a multidimensional array, then median A treats the values along the first array dimension whose size is greater than 1 as vectors. The size of M in this dimension becomes 1 , while the sizes of all other dimensions remain the same as in A. If A is a table or timetable, then median A returns a one-row table containing the median of each variable.

For a symmetrical distribution such as the normal distribution, the median is equal to the mean, mu. For a skewed distribution such as the Weibull distribution, the median and the mean may not be equal. Probability distribution, specified as one of the probability distribution objects in the following table. Median of the probability distribution, returned as a scalar value.

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 :.

Some things that the code may need to address that I tried attempted to address is scenarios of what we would do if the vector had an even or odd amount of elements and what if the numbers are not in ascending order?
