I have the following array:

A=[1; 2; 3; 4];

I then make an array B:

B=[]

I then use a for loop to assign each number in array A a color.

    for j=1:length(A)
        if A(:,i)=1
            B=('blue');
        elseif A(:,i)=2
            B=('yellow);
        elseif A(:,i)=3
            B=('green');
        else A(:,i)=4;
            B=('black');
        end
    end

The B array has all of the colors.

I want to use fprintf to to have A and B as the headings of the table, where column A has [1; 2; 3; 4] and column B has all of the colors next to their corresponding number from the for loop.

How can I do this?

I really don't know how this is different than what I already answered in this question. The only difference is that here B is not an array despite you calling it one.

Perhaps you mean this?????

A=[1; 2; 3; 4];
for j= 1 : length(A)  
  if A(j)==1    
    B='blue';    
  elseif A(j)==2    
    B='yellow';    
  elseif A(j)==3    
    B='green';    
  elseif A(j)==4    
    B='black';    
  end
  fprintf('%d    %s\n', A(j), B);
end
