Pseudorandom character matrix generation
显示 更早的评论
Generate a 10x10 matrix with the letters 'b', 'd', 'p', 'q' in randomized order. Every refresh should produce a new randomized matrix.
This is to simulate the bdpq test. Should be a pretty simple task, but seems to be otherwise!

If you want a 10x10 char array, you can also use indexing:
source = 'bdpq';
Array = source(randi(end,[10 10]))

s = {'b', 'd', 'p', 'q' } ;
S = cell(10) ;
for i = 1:10
for j = 1:10
t = s(randperm(4,4)) ;
S{i,j} = [t{:}] ;
end
end
S
