Hi

I'm submitting a new function to octave which has been added to matlab in the
version 2011b (I asked in ##matlab and seems it's not present in 2011a).

It's a ridiculously simple thing but if someone codes is ever dependent on it,
it's already here. I asked to get some corner cases tested with the following
code in matlab


function test_min_only (varargin)
  narginchk (3)
  disp ('only minargs is ok')
end

function test_same (varargin)
  narginchk (3, 3)
  disp ('min and max can be equal')
end

function test_inf (varargin)
  narginchk (3, inf)
  disp ('can use inf as max')
end

function test_zero (varargin)
  narginchk (0, 3)
  disp ('can use zero as min')
end

function test_zero_both (varargin)
  narginchk (0, 0)
  disp ('can use zero as both min and max')
end

function test_negative (varargin)
  narginchk (-1, 3)
  disp ('min can be negative')
end

test_min_only (1, 2, 3)   # fails
test_same (1, 2, 3)       # works
test_inf (1, 2, 3)        # works
test_zero (1, 2, 3)       # works
test_zero_both ()         # works
test_negative (1, 2, 3)   # works
