I need to make a dice with riged odds and plot the results in a bar chart. The dice and the riged odds part gives me the result im seeking, but i dont know how to convert these anwsers into a bar chart seeming my x- values keeps on changing value.
clc, clear all
for index=(1:1000)
x=randi([1,13]);
if x==1
x=5
elseif 2<=x && x<=5
x=randi([1,2])
elseif 6<=x && x<=7
x=4
elseif 8<=x && x<=9
x=6
elseif 10<=x && x<=13
x=3
end
end
Thanks

You might find the histogram function useful.

THANK YOU SO MUCH <3
This is my code, there is probaly an easier way to solve this problem. But who cares!
clc, clear all
a=1;
A=[1: a];
for i=(1:1000)
a=0
a=1+a;
x=randi([1,13]);
if x==1
x=5
elseif 2<=x && x<=5
x=randi([1,2])
elseif 6<=x && x<=7
x=4
elseif 8<=x && x<=9
x=6
elseif 10<=x && x<=13
x=3
end
A(i)=x;
a=a+1;
end
histogram(A)

Consider creating an empty matrix prior to the 'for' statement. Then write the results to that matrix.

I have now updated by problem to 1000 rolls ofthe dice. Is there a way for matlab to put these values into the matrix and if so how?

If you haven't already solved this, search for something like "creating arrays with loops". That should give you some examples on how to proceed.
