[minval, minidx] = min([x1,x2,x3,x4,x5,x6,x7,x8,x9,x10]);
switch (minidx)
case 1: image(x1);
case 2: image(x2);
case 3: image(x3);
[etc]
end
If that seems a bit clumsy (as it should), then considering storing your images a different way. http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

Please follow the link Walter has posted. If you store the images in a cell like x{1}, x{2}, ... the processing is much easier. Hiding an index in the name of a variable is very inconvenient and prone to errors.

kash, as you step through it with the debugger, which case statement is it going into? Also, you might have the last case be "otherwise" instead of case 10. Also are you sure you didn't make a typo? MATLAB will create new variables dynamically and y4 is different than x4.
