changing elements of a multidimensional array using matlab
显示 更早的评论
Hey guys, Im kind of lost. I am making a m*n zero matrix. I want to change each element into either 1,2 or 3. If the array is 1 by n i can do it but i can't do it for m*n i am using for loops this is what i would did.
x=zeros(1,randi(10)) n=length(x) for m=1:n x(m)=randi(3) end This works for 1*n but what would i do if its like 2 by n or bigger i tried this
x=zeros(2,randi(10)) [r,c]=size(x) for m=1:r for p=1:c x(p)=randi(3) end x(m)=randi(3) end this only changes the first 3 elements and the 1st two of the second row. Please help thanks

m + randi(10);
n = randi(10);
x = zeros(m,n);
for p = 1:m
for q = 1:n
x(p,q) = randi(3);
end
end
You could also dispense with all this nonsense and simply do this:
x = randi(3,randi(10,1,2));
