import multiple files with for loop

Hello, i need to know how can i do this with a double for loop,

sza10str2 = importdata("10.0_02_streams.out");
sza10str4 = importdata("10.0_04_streams.out");
sza10str8 = importdata("10.0_08_streams.out");
sza10str16 = importdata("10.0_16_streams.out");
sza30str2 = importdata("30.0_02_streams.out");
sza30str4 = importdata("30.0_04_streams.out");
sza30str8 = importdata("30.0_08_streams.out");
sza30str16 = importdata("30.0_16_streams.out");

i tried something like this but it doesn't woks.

Any suggestions?

Thank you..

x = [10.0 30.0];
y = [02 04 08 16];
for i = 1:2
    for j=1:4
        sza{i}streams{j} = importdata(sprintf('%d_%d_streams.out', x(i),y(j)));
    end
end

sza{i,j} = importdata(sprintf('%.1f_%02d_streams.out', x(i),y(j)))
