Hello,
I have a variable B which outputs about 100 cells. Assuming N = 4, how do I go about obtaining cell2mat(B(N(1)) in a new variable x_1, cell2mat(B(N(2)) in x_2, and so forth? Currently I am using:
for cnt = 1:N
hold on;
x = cell2mat(B(cnt));
end
Thanks in advance!

In general, you probably do not want to be doing this. Why do you want x1, x2, ... It is only going to lead to evil eval statements later.

On a separate note, is there a function in MatLab that will allow me to detect colors within an image? I have broken down the image into a matrix via the imread() function. How can I go about detecting whether the leaf detected is green or yellow or so on? Thanks in advance.

"hold on" is for graphics. It has nothing to do your operation.
Depending on your cell array B, you may not need cell2mat. See this example:
B={rand(2),magic(2),rand(3),magic(3),rand(4),magic(4)};
[x1,x2,x3,x4]=B{2:5}
