arrays - Using percentage function with accumarray -

i have 2 arrays:

otpcororder = [61,62,62,62,62,62,62,62,62,62,62,62,65,65,...] aprefcor = [1,3,1,1,1,1,1,1,1,1,2,3,3,2,...] 

for each element in otpcororder there corresponding element in aprefcor. want know percent of number 1 each set of unique otpcororder follows:

otpcororder1 = [61,62,65,...] aprefcor1 = [1,0.72,0,...] 

i have this:

[otpcororder1,~,idx] = unique(otpcororder,'stable'); ans = otpcororder1 = [61,62,65,...]; 

and used work "accumarray" used "mean" or "sum" function such this:

aprefcor1 = accumarray(idx,aprefcor,[],@mean).'; 

i wondering if there exists way use "prctile" function or other function gives me percent of specific element example "1" in case.

thank much.

this 1 approach:

%// make non-zero values 0 aprefcormask = aprefcor == 1;  %// have done [otpcororder1,~,idx] = unique(otpcororder,'stable');  %// find number of each unique values counts = accumarray(idx,1);  %// find number of ones each unique value sumval = accumarray(idx,aprefcormask);  %// find percentage of ones results perc = sumval./counts 

results:

inputs:

otpcororder = [61,62,62,62,62,62,62,62,62,62,62,62,65,65]; aprefcor = [1,3,1,1,1,1,1,1,1,1,2,3,3,2]; 

output:

perc =  1.0000 0.7273      0
