Take your function and create a table over the range of variables you want.

IN MATHEMATICA
F[x_,y_] = Sin[x 5] Sin[y 5];
data = Table[F[x,y],{x,0,1,0.1},{y,0,1,0.1}];
ListPlot3D[data]

Then export that data

Export["c://data.MAT", data];

This is a Matlab matrix filetype that you can then import into matlab.
