8.25 Suffixes for variable

Suffixes can get some numerical value (like its size, maximal or minimal value, the sum of elements and so on) of the data array in variable and use it later as usual number in command arguments. The suffixes start from point ‘.’ right after (without spaces) variable name or its sub-array. For example, a.nx give the x-size of data a, b(1).max give maximal value of second row of variable b, (c(:,0)^2).sum give the sum of squares of elements in the first column of c and so on.

The full list of suffixes are:
