Accumarray

MATLABs most commonly used 3-d plotting tools surf and mesh require rectangular grids to plot in 3-d, not x,y,z triples. This function converts arrays of x,y,z triples into rectangular grids to use with surf, mesh, etc.common usage:[x y z] = xyzplotter(xin,yin,zin)xin,yin,zin are n x 1 arrays... Platforms: Matlab

Surprisingly, I never came across the simple solution of aggregating data using accumarray. Accumarray needs indices supplied to aggregate too. Combining this with the Unique function, the user can quickly and conveniently aggregate data using any available and appropriate funciton supported by... Platforms: Matlab

accumSeasonTS- aggregate timeseries to solstices and equinoxesUsing G. Cardillo function to compute solstices and equinoxes, this function will aggregate time series data (e.g. Precipitation) to seasonally summarized results. To accomplish this three core functions are used: eqnsol, unique, and... Platforms: Matlab

The class ndSparse defined in this submission will give a lot of the functionality of N-dimensional sparse arrays for N possibly greater than 2. However, it should really be thought of as a way of starting with an ordinary MATLAB sparse matrix and reshaping it to have N dimensions. In other... Platforms: Matlab
