This is a function to import vector file archives from oommf into Matlab

Oommf vector files must be written with the output Specifications "text %g"
instead of the default "binary 4" option. And the type of grid must be

Vector files will be imported into the object "data" which will have this
field: current applied magnetic field
xmin: minimum x value
xnodes: number of nodes used along x
xmax: maximum x value
ymin: minimum y value
ynodes: number of nodes used along y
ymax: maximum y value
zmin: minimum z value
znodes: number of nodes used along z
zmax: maximum z value
datax: component x of vector on data file
datay: component y of vector on data file
dataz: component z of vector on data file
positionx: x positions of vectors
positiony: y positions of vectors
positionz: z positions of vectors

We have created with Oommf the archive test.omf (included on the zip). To open it into "data"


Now we can make a 2D vector field


or calculate the divergence and plot it

There was a problem with 3D data files that now is solved.

An updated version is now available. The older version scan line by line for the data and took 30 s to upload the test.omf file into Matlab, this version uses textscan()and takes only about 0.17 s.
