Geotiffwrite is ploting the map upside down! (latitude only)

I have a brazilian map in matlab (to study precipitation). When I try to convert the metrics results to geotiff (to plot in ArcGis), it is going upside down (i mean, the lattitude is inverted, but the longitude is ok).
Why is this happening? What Can I do?

Perhaps the latitude values are positive? For Brazil (in the southern hemisphere) they should be negative.

Try this:
plot(.......... % or whatever you do
% Get the axes object.
ax = gca
% Flip the y axis direction.
ax.YDir = 'reverse'

It may be late for the person who originally asked this question, but I will leave an answer here in case someone is struggling with the same issue. I had the same problem for a dataset of South America, which includes both positive and negative latitudes. The problem was the way I was defining the spatial reference R, with georasterref. I went to the documentation and found that it was not recommended, instead, there is georefcells. It works in a similar way BUT it allows to set if the columns should start north or south. This solved the problem!
