MATLAB: Interpolation of Data on Different Grids

gridinterpolationlatitudelongitudeMapping ToolboxMATLAB

I have a 2-D data (ocean depth) on a latitude-longitude grid. (That is, the ocean depth is specified at each latitude and longitude. The latitude coordinates and longitude coordinates are separated by 1 deg each.) Question: How do I interpolate this data onto a fixed-distance grid (with an interval of, say, 100 m by 100 m)?
Thanks.
