Hallo everybody, I have a matrix of latitudes of earth locations from pool to pool obtained from a satellite pass. the matrix is 20x2573 double with many values set as NaN. I need only the latitudes of the Mediterranean Sea: 28°N to 46°N Latitude. Does anyone knows how I can limit my matrix to only the latitudes needed without changing the shape of it. that means the rows must stay 20 because they refer to 20 herz values and with NaN values too. Big thanks in advance!
