'Out of Memory' error but no change in code

So, its been a few weeks since i last ran this code. Now every time i run it i get an out of memory error. I've restarted my computer, increased the virtual memory, i'm not running any additional programs.

The code is simple but requires a heavy dose of processing to concatenate the 3D Matrix. Here is the code:

cd 'C:\ThermalImages'

img1=dlmread('image1.csv', ',', 7,1);

img2=dlmread('image2.csv', ',', 7,1);

img3=dlmread('image3.csv', ',', 7,1);

img4=dlmread('image4.csv', ',', 7,1);

img5=dlmread('image5.csv', ',', 7,1);

img6=dlmread('image6.csv', ',', 7,1);

img7=dlmread('image7.csv', ',', 7,1);

img8=dlmread('image8.csv', ',', 7,1);

img9=dlmread('image9.csv', ',', 7,1);

img10=dlmread('image10.csv', ',', 7,1);

Matrix3D = cat(3,img1, img2, img3, img4, img5, img6, img7, img8, img9, img10);

figure;

xslice=120;

yslice=160;

zslice=1;

h=slice(Matrix3D,xslice,yslice,zslice,'spline');

colorbar;

caxis([75,100]);

shading interp;

colormap('jet');

set(gca,'ZDir','reverse');

figure;

j=slice(Matrix3D,xslice,yslice,zslice,'spline');

colorbar;

caxis([75,100]);

shading interp;

colormap('jet');

set(gca,'Zdir','reverse');

view([180,0]);

I'm basically taking 10 excel spreadsheets from CSV format and concatenating them into a 3D Matrix so I can take a slice down the middle. I used to run into memory errors if i tried to run the code multiple time (4-5) in a row. Now it won't even run once. I haven't changed anything about the code.

Is there anything i can do to reset any settings in MatLab R2013a to get back to its original state? Is there a more efficient way to process this data? Is there anything else i can do to get back to a working system?

Thank you, Michael

After the out of memory error, can you type 'whos' and post the output here?
