Plot from Mathematica to Matlab
I have this problem in Mathematica :
L=16;
f[x_]:=-x;
mlat = Table[2 RandomInteger[] -开发者_如何学Go 1, {L}, {L}];
ArrayPlot[mlat, ColorFunction -> (If[# == 1, White, Black] &), Mesh -> All]
and I did this in Matlab:
L=16;
f=@ (x) -x;
mlat=2*randint(L,L)-1;
if mlat(:,:)==1
plot(mlat,'ws')
hold on
else
plot(mlat,'ks')
hold off
grid on
end
but I can't get the graph.
First, you want to create an array with only ones and zeros, which you do using randi
L = 16;
mlat = 2*(randi([0,1],L,L)-0.5);
Then, you can display this as an image (I like to open an new figure for every plot)
figure
imshow(mlat,[]) %# [] scales to min...max
To make the image bigger, set axes size to 90% of the figure window
set(gca,'Units','normalized','Position',[0.05 0.05 0.9 0.9],'visible','on')
Note that the axes label correspond to the index of matrix elements, so (1,1) is top left.
