MATLAB: I need to know how to organize a find statement into a set order with characters instead of it’s number’s. I want information to come out like below.

findmatlab function

A=[18 33 31 34 15 37 10.5 48 50 38 35 39 42 33 31 1 5 9 13 11 27 35 -1 46 22 6 19 36];
volt=round(A);
%newscrip below
function [fruit_fin]=Program05b(volt)
B=[1:1:28]
O=[find(volt>=31 & volt<=40,28)]
G=[find(volt>=21 & volt<=30,28)]
P=[find(volt>=11 & volt<=20,28)]
A=[find(volt>=0 & volt<=10,28)]
U=[find(volt<0 | 40<volt,28)]
fruit_fin=[O,P,G,A,U]
end
% anwers % I know how to get it into a table.

Best Answer

discretize your data.
A=[18 33 31 34 15 37 10.5 48 50 38 35 39 42 33 ...
    31 1 5 9 13 11 27 35 -1 46 22 6 19 36];
volt=round(A);
edges = [-Inf  0    11   21   31   41   Inf];
bins =     {'U', 'A', 'P', 'G', 'O', 'U'};
results = discretize(volt, edges, bins);
Elements in volt in the range [-Inf, 0) will map to 'U' in results. I tried to indicate that with spacing in the code above, where U is between -Inf and 0.
Elements in volt in the range [0, 11) will map to 'A' in results. The other bins behave similarly until you reach the last one.
The last bin is special. Elements in volt in the range [41, Inf] will map to 'U' in results. The last bin contains both its endpoints, not just the left one.
