Geolocation matrix problem, #Matlab

Hello,

I'm working with a matrix for 100 days,

    latitude       3248x152x100            394956800  double              
    longitude.      3248x152x100            394956800  double              
    speed          3248x152x100            394956800  double

and I'm trying to geolocation the data, in this way my latitude and longitude variables, there are just .....(*speed stays the same)

    latitude       3248x152                        
    longitude      3248x152

If anyone can help me here I'd greatly appreciate it, thanks...

The question is unclear. The data does not look like a "matrix". What does "*speed stays the same" mean?

Are you dealing with a grid of irregularly spaced nodes covering 3248 longitudes and 152 latitudes which vary with time?
