vector or list percentile( list,vector ) |
From a given list of V vectors, each with the same number, N, of elements, and a set of P percentiles, computes a new list of P vectors, each containing N elements - one percentile for each of the N elements across all V input vectors. The set of percentiles is supplied as the second argument and can be a vector, a list or a single number. If it is a single number then the result will be a single vector rather than a list of vectors; however, supplying a vector or list with just one percentile will result in a list of one vector result. The function complements the Percentile module, which acts directly on GRIB fields.

Returns the vector of the sign of the values of the input vector at each element-1 for negative values, 1 for positive and 0 for null values. Missing values are retained, unaltered by the calculation.
