SYNOPSIS
SEISMIC UNIX NOTES UNISAM2 - UNIformly SAMple a 2-D function f(x1,x2)
unisam2 [optional parameters] <inputfile >outputfile
Required Parameters:
none
Optional Parameters:
x1= array of x1 values at which input f(x1,x2) is sampled
... Or specify a unform linear set of values for x1 via:
nx1=1 number of input samples in 1st dimension
dx1=1 input sampling interval in 1st dimension
fx1=0 first input sample in 1st dimension
...
n1=1 number of output samples in 1st dimension
d1= output sampling interval in 1st dimension
f1= first output sample in 1st dimension
x2= array of x2 values at which input f(x1,x2) is sampled
... Or specify a unform linear set of values for x2 via:
nx2=1 number of input samples in 2nd dimension
dx2=1 input sampling interval in 2nd dimension
fx2=0 first input sample in 2nd dimension
...
n2=1 number of output samples in 2nd dimension
d2= output sampling interval in 2nd dimension
f2= first output sample in 2nd dimension
...

=spline for bicubic spline interpolation
NOTES:
The number of input samples is the number of x1 values times the
number of x2 values. The number of output samples is n1 times n2.
The output sampling intervals (d1 and d2) and first samples (f1 and f2)
default to span the range of input x1 and x2 values. In other words,
d1=(x1max-x1min)/(n1-1) and f1=x1min; likewise for d2 and f2.
Interpolation is first performed along the 2nd dimension for each
value of x1 specified. Interpolation is then performed along the
1st dimension.
