when I obtain the data for the array I'm having the ID in a 22x1 double data, and when I run the if condition I have a problem with the size
"Unable to perform assignment because the indices on the left side are not compatible with the size of the right side."
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/708362/image.png)
for i = 1:length(T1.ID)
if ID(i) == 0
EI(i) = 'Very high';
elseif ID(i) == 1
EI(i) = 'High';
elseif ID(i) == 2
EI(i) = 'Medium';
elseif ID(i) == 3
EI(i) = 'Low';
end
end
the other values are taking a colum of the table generated. Sorry, I'm kind of new with matlab, thanks in advance

I think it should put into a cell array:
EI = cell(1,length(T1.ID)); % Cell array
for i = 1:length(T1.ID)
if ID(i) == 0
EI{i} = 'Very high';
elseif ID(i) == 1
EI{i} = 'High';
elseif ID(i) == 2
EI{i} = 'Medium';
elseif ID(i) == 3
EI{i} = 'Low';
end
end

It's not clear what 19 variables you have in the table T1, but I suspect your error will disappear via...
for i = 1:length(ID) % change from T1.ID to just ID
if ID(i) == 0
EI(i) = 'Very high';
elseif ID(i) == 1
EI(i) = 'High';
elseif ID(i) == 2
EI(i) = 'Medium';
elseif ID(i) == 3
EI(i) = 'Low';
end
end
