Reorder and regrid contour data

## 1. SYNOPSIS

[x,y,z] = contoxyz(data, iz, yi )

## 2. DESCRIPTION

This Matlab function selects specified z variables from an input contour file. It also reorder the columns to have x and y the least and next varying values. Data are also regridded on a specified grid along y values.

## 3. PARAMETERS

data

  Array containing contour data. The x and y must be located in the frist two columns,respectively.

iz

  Column number of the z variable to retrieve from the data matrix.

yi

  A vector on which contour data should be interpolated. This is necessary because some contour data do not have values at identical y in different profiles.

## 4. RETURNS

x

  A vector containing x values.

y

  A vector containing y values (same as yi).

z

  An array containing the desired z values,interpolated on grid defined by x and yi values.
