My code currently creates a board of size n x n (user input) What I want to do now is to have certain positions on this board be called "kings", and I want roughly 1 king per 20 spaces i.e for a 10 x 10, there are 100 spaces so 5 kings. How do I randomly pick a board position to put a king?
function board = makeboard(size)
board = cell(size+1,size+1);
% initialize the board
for i=1:size+1
for j=1:size+1
if i==1
if j<=size
board{i,j+1} = j;
board{j+1,i} = j;
end
elseif j==1
% do nothing
else
board{i,j}= 'x';
end
end
end
amount=size*size;
king=amount/20;
king=floor(king);
end

Sorry, all of the normal ways of doing this involve using the MATLAB function named size(), which is not possible in your code because you named a variable "size". But you could change
else
board{i,j}= 'x';
to
elseif rand < 1/5
board{i,j} = 'k';
else
board{i,j} = 'x';
