I have a 290x480x90 array where the x and y are coordinates in UTM. I'd like to convert them to degrees minutes seconds and I'd normally use the function utm2deg from the file exchange, but this requires the lat and lon arrays to be of equal length. Is there another solution? Thanks

I don't understand which column in your 3D array contains X coordinates and which one contains Y coordinates.

It sill be about saying something like:

X=[];

for i=1:90

X=[X; data(:,7,i)]; %7th column are X coordinates

end

Hm, so is i the y coordinates or frequency?

My array is 91(freq)x489(lon)xlat(280). (I made a mistake in OP sorry)

I tried:

X=[];
for i=1:280
    X=[X; vardata(:,7,i)]; %7th column are X coordinates
end

but this outputs a single 25480x1 array.

I am looking to get lat and lon?

Should I be repeating this for X and Y, and then running the utm2deg function?
