Export matlab variable to be imported in QGis

Dear all,

I need to export a 1000x1000 matrix containing sound pressure level of a specific region to be later imported at QGis.

I tried to do that using netCDF files, which is ok, however the coordinate system is not the same than in QGis (it is used the WGS84 coordinate system) and when I import the file there it is not in the correct location.

So, my question is, how can I export my variable maintaing the correct coordinate system/or change the coordinate system in matlab to correspond to the same coordinate system in QGIs.

Thank you in advance.
