I have a cell array that looks like:
a={apples} {1}
{orange} {2}
{apples} {3}
{Pear} {4}
{apples} {5}
I want to get like items together in their own matrix like:
a1= {apples} {1}
{apples} {3}
{apples} {5}
a2= {orange} {2}
a3= {pear} {4}
Thank you!

One way:
a=sortrows(a,1)

fields=fieldnames(Sa);
for i=1:numel(fields)
Sa.(fields{i})
end
