idamnjanovic@1 1 function z = iswhole(x,epsilon)
idamnjanovic@1 2 %ISWHOLE Determine whole numbers with finite precision.
idamnjanovic@1 3 % Z = ISWHOLE(X,EPSILON) returns a matrix the same size as X, containing
idamnjanovic@1 4 % 1's where X is whole up to precision EPSILON, and 0's elsewhere.
idamnjanovic@1 5 %
idamnjanovic@1 6 % Z = ISWHOLE(X) uses the default value of EPSILON=1e-6.
