## Description

GRIDSCALE Scale a grid.

[ GRID ] = GRIDSCALE( GRID, S ) Scaling a grid with the factors specified in S. S can either be a real array with constant scaling factors for each direction, for example S = [1 2 1] for a 2 times scaling in the y-direction. Alternatively, S can be a cell array with string expressions for the scaling factor.

Examples
1) Scale a circle by a factor of 2 in the x-direction
  grid = spheregrid();
grid = gridscale( grid, [2 1 1] );

2) Scale the upper half of a rectangle to form an angle
  grid = rectgrid();
grid = gridscale( grid, {'1-(y>0.5).*(y-0.5)' 1} );
