EF = maskrectf(F,[X1 Y1 X2 Y2]) masks (i.e., puts zeros) in a
rectangular area of coordinates [X1 Y1 X2 Y2] in the vector/scalar
field(s) F. By default, the coordinates are given in mesh units.
Specify maskrectf(F,[X1 Y1 X2 Y2],'phys') to give them in physical
units (e.g. in mm).
See zerotonanfield to mask using NaNs instead of zeros.
If no output argument, the result is displayed by showf.
