Integer span function. Arguments start Single scalar integer value at which the span will start.
Description Computes a span of integer values beginning at start and ending at finish .
Each element will be separated by the value of stride . The stride must be positive but start and finish can be any valid integers. Use NCL's implicit coercion rule with ispan to generate 1D float arrays. Multiplying the ispan function by a float value causes NCL's implicit coercion to make the result a 1D float array.
