回答： Patel Keyur 2022-1-7

Hello All, I Have code below. I want to create an array with elements [ 5, 10, 15, 20,25, 30, 35, 40, 45, 50, 55, 60, 65, 75, 80, 85, 90, 95, 100] and I want replace if statement if (stateCount(n)> 5 && stateCount(n)<= 10) with value from an array 5 and 10. How can I do that. Any tips will gladly welcome

stateHit = zeros(length(stateCount),20);  
  for n = 1:length(stateCount)
 if (stateCount(n)<= 5)
        stateHit(n,1) = 1;
 else
 if (stateCount(n)> 5 &&  stateCount(n)<= 10)
            stateHit(n,2) = 1;
else
if (stateCount(n)>10 &&  stateCount(n)<= 15)
        stateHit(n,3) = 1;
else
if (stateCount(n)> 15 &&  stateCount(n)<= 20)
        stateHit(n,4) = 1;
else
 if (stateCount(n)> 20 && stateCount(n)<= 25)
    stateHit(n,5) = 1;
else
if (stateCount(n)> 25 &&  stateCount(n)<= 30)
    stateHit(n,6) = 1;
end
end
end
end
 end
 end 
 end

Many thanks in advance

在 MATLAB Online 中打开

YourDividingArray = 5:5:100;
[bincounts, HistcIndex] = histc(StateCount, [-inf YourDividingArray(2:end)]);
StateHit( sub2ind(size(StateHit), HistcIndex, 1:size(StateHit,2)) ) = 1;

Or if you prefer,

HistcIndex = max(1, floor(StateCount / 5));
StateHit( sub2ind(size(StateHit), HistcIndex, 1:size(StateHit,2)) ) = 1;

Hi Walter, I use code like that but I have error

??? Undefined function or variable 'StateHit'.

Error in ==> short_code_test at 4 StateHit( sub2ind(size(StateHit), HistcIndex, 1:size(StateHit,2)) ) = 1;

Here is the code I try

StateCount = value; HistcIndex = max(1, floor(StateCount / 5)); StateHit( sub2ind(size(StateHit), HistcIndex, 1:size(StateHit,2)) ) = 1; disp(StateHit);

Thanks for help in advance
