Index Range FunctionsRange functions are executed from left to right if more than one appears in a single index list. The following range functions reduce the rank of the result, like a scalar index: min minimum of values along index
The following functions do not change the rank of the result, like an index range. However, the length of the index is changed as indicated by +1, 1, or 0 (no change): cum, psum +1, 0, partial sums of values along index
For example, given a twodimensional array x, x(min,max) returns the largest of the smallest elements along the first dimension. To get the smallest of the largest elements along the second dimension, use x(,max)(min).
