Determine the number of "for" loops by the user

Hi everyone
I want to write a code that takes the number of uncertain parameters from the user and creates a "for" loop according to their number and performs the calculations.
for example:
The user enters the number 4 as the number of uncertainty parameters and the code puts 4 "for" loops in a row. This way :
for i=1:I
for j=1:J
for k=1:K
for r=1:R
"calculations"
end
end
end
end
Is this possible in MatLab?

I think you can avoid using loops.....can you tell us what are those calculations?
I,J,K,R they will be always same?

% The number of iterations
ni = [3 4 2 2]; % 4 iterations [I J K R]; i is innerest loop
idx = ones(size(ni)); % first index
k = cumprod(ni);
for i=1:prod(ni)
% calculate index (ignore this part if calculation independent of index)
ii = i;
for j=length(ni):-1:2
ir = rem(ii-1, k(j-1)) + 1;
idx(j) = (ii - ir) /k(j-1) + 1;
ii = ir;
end
idx(1) = ii;
disp(idx)
% do calculation depending on idx
end
