fnddat
This subroutine searches an array and returns a new array.
Usage

x2
Input
Maximum valid point
xnew
Output
Screened x array
np1
Input

code
Input
Search "x" or "y" data array
Returns
Output
The new array
Details
This subroutine searches a data set of x and y values for a specified range of data and returns two
new arrays with the screened data. Use this routine in other routines to remove unwanted or bad
points from measured data.
The x, y, xnew, and ynew parameters are all adjustable dimensioned arrays. The calling routine
should dimension them all the same.
The code parameter searches either the x data or y data. For example, in most measurement
routines, either the voltage or current is fixed, and the other variable is measured. The measured
variable is normally what is screened.
Example
fnddat(&x, npts, &y, npts1, x1, x2, &xnew, np1, &ynew, np2, &np, code)
