numpy.percentile # numpy.percentile(a, q, axis=None, out=None, overwrite_input=False, method='linear', keepdims=False, *, weights=None, interpolation=None) [source] # Compute the q-th percentile of the data along the specified axis. Returns the q-th percentile (s) of the array elements. Parameters: aarray_like of real numbers Input array or object that can be converted to an array. qarray_like ...
prctile Percentiles of a sample Syntax Y = prctile(X,p) Description Y = prctile(X,p) calculates a value that is greater than p percent of the values in X. The values of p must lie in the interval [0 100]. For vectors, prctile(X,p) is the p th percentile of the elements in X. For instance, if p = 50 then Y is the median of X.
Discover how to master matlab prctile and unlock powerful data analysis techniques. This guide simplifies percentiles for efficient coding.
However, using the `prctile` function is more convenient and efficient. 9. What is the difference between percentile and quantile in MATLAB? In MATLAB, percentiles represent a value below which a certain percentage of the data falls, while quantiles represent a value that divides the data into equal groups.
To calculate percentiles you can use matlab's function prctile. One of the ways to call the function is prctile(X,p) where X is your vector and p is a percentage in the range [0-100]. Note that this would be what you call "bottom percentage" In your case, you can get the bottom n% as follows: ninetyPercentBottom = prctile(X,n) ninetyPercentBottomShare = sum(X(X
To calculate the percentile of a vector in MATLAB, you can use the prctile function. The prctile function takes two inputs: the vector of data and a percentile value (between 0 and 100).

Using the prctile function will only get you the value of a given percentile. What you're after is the column # of values above the 80th percentile and below the 20th percentile for each row.
