Thanks in advance for any help that anyone can provide on this topic.
If this question belongs on a different news group I apologize and
request a pointer to that group.  If it is some sort of FAQ, then
I would love to read the FAQ list for such a thing.

I am using Mathematica (on a Mac) for reading in a data file
with points with a non-square (non-regularly spaced) grid of points.

(i.e. sample points that look like)

	0	0		0				0
	
	0	0		0				0


	0	0		0				0





	0	0		0				0







	0	0		0				0



I am using the interpolation function that mathematica offers

	Function = Interpolate[ <datalist>, InterpolationOrder->1]


As I understand the manual, this should create a function which provides as output
the above data with linear interpolation between the points.  However the output
that I get from this is definately NOT a linear interpolation, but something
that looks quadratic.

Can anyone tell me how to fix this?  Is therea simple work-around?
