Same as interp(). NOTE: The X value must be monotonically increasing. Or more simply, the next number must be larger than the previous number in an array. Arguments and Return Values Arguments: An X and Y numerical array pair and a new X numerical array. Return Value: A numerical array of Y values which is resampled to the new X numerical array Usage Syntax: interp(y1 = VAL, x1 = VAL, x2 = VAL [,ignore = VAL] ) y1 - a set of Y values that correspond to the original or from X values x1 - a set of X values that correspond to the object Y values x2 - the new set of X values which will be the resampling source data ignore - ignore value Examples dv> original struct, 2 elements data: 1x1x1000 array of float, bsq format [4,000 bytes] xaxis: 1x1x1000 array of float, bsq format [4,000 bytes] dv> new_xaxis 1x1x50 array of float, bsq format [200 bytes] dv> interpolated_data = cinterp(original.data, original.xaxis, new_xaxis) 1x1x50 array of float, bsq format [200 bytes] Images
