# Matlab Tinycode

Back in second year of my undergraduate degree, we were asked in our MATLAB algorithms design class to write the smallest piece of code to produce the following:

After several attempts my final solution was to encode the face patterns in integers of a matrix. The command spy will plot a logical matrix. This is what I came up with.

```
function Dice(k)
hold
rectangle('Po', [0 0 4 4], 'F', 'k', 'Cu', .2)
spy(bitget([56 0 62
32 21 32
62 0 56], k), 'w', 99)
axis off
```

In this "competition", only non-whitespace characters were counted. There were a few things like the function definition, hol and axis which were compulsory. I didn't beat the lecturer's solution but I did come up with a solution which I was very happy with.

Last night I was kind of bored and wanted something to do. I decided I'd try and make a random Voronoi diagram which fits in a Tweet.

I'm not quite as happy with this code compared to my Dice code, but I am still going to share it :)

```
v=rand(15,3)
[x y]=meshgrid(0:5e-3:1)
hold
scatter(x(:),y(:),2,v(dsearchn(v(:,1:2),[x(:) y(:)]),:))
plot(v(:,1),v(:,2),'k.')
```

Pretty short! And the output is pretty!
