Index exceeds the number of array elements (11)

Hello !!

label = [7 11 15 10 4 16 17 18 8 12 9 19 5 13 20 14 6 1 2 3 21 22 23 24 25 26 27 28 29 30]

n = 30;

Color = 11;

pewar = zeros(nCUE,1);

B = randperm(numel(Color));

B = [2 1 4 5 7 11 6 8 3 9 10]

for i = 1 : size(label,1)

if i <= size(B,2)

pewar(i) = B(label(i,1));

else

pewar(i) =0;

end

end

Index exceeds the number of array elements (11).

Error in color_coba (line 323)

pewarCUE(i) = B(labelCUE(i,1));

how to fix that problem.

label should have a value of 1 2 3 and in the order above it and will be assigned a random value B with a range of 11. if the value of B is run out it will be given a value of 0. but the position of the label doesn't change

B = randperm(numel(Color)); seems to be an error. Since Color is a scalar, numel(Color) = numel(11) = 1. So B=1.

I believe you want:

B = randperm(1:Color)

Think about what happens on the 6th loop, i=6, label(i,1) = 16. Since i=6 <= 11, the if statement returns true.

then, B(label(i,1)) = B(16). What should B(16) return, if B only has 11 elements?

Instead I think your if statement needs to be:

if label(i) <= size(B,2)

thank very much Kenneth George , it solve
