MATLAB Language Usage of `accumarray()` Function Finding the maximum value among elements grouped by another vector
Example
This is an official MATLAB example
Consider the following code:
month = [1;1;2;3;8;1;3;4;9;11;9;12;3;4;11];
temperature = [57;61;60;62;45;59;64;66;40;56;38;65;61;64;55];
maxTemp = accumarray(month,temperature,[],@max);
The image below demonstrates the computation process done by accumarray in this case:
In this example, all values that have the same month are first collected, and then the function specified by the 4th input to accumarray (in this case, @max) is applied to each such set.
