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. By default, missing data is removed before computing.

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. The value of m is the 50th percentile of the probability distribution. The input argument pd can be a fitted probability distribution object for beta, exponential, extreme value, lognormal, normal, and Weibull distributions. Create pd by fitting a probability distribution to sample data from the fitdist function. This function fully supports GPU arrays.

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.

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. If A is a matrix, then Q is a matrix with n rows. For example, if A is a matrix, then quantile A,p,2 operates on the elements in each row. For example, if A is a matrix, then quantile A,n,[1 2] operates on all the elements of A because every element of a matrix is contained in the array slice defined by dimensions 1 and 2.

Note If the timeseries object is uniformly sampled, then the normalized weighting for each time is 1. Answers 1. Walter Roberson on 4 Nov Specify the 'Quality' name-value pair to indicate which data samples are considered missing. In the first case, since the median will be exactly one of the values, a-median a will be exactly 0 for all the entries exactly equal to the median, and abs of that will be 0, and min of values that are non-negative because of the abs will be 0 written into y and idx will be the position of the first such value. Objects lock when you call them, and the release function unlocks them. Include missing values in A when computing the median. Search Support Clear Filters.
