save matrixs in different names

Good morning\evening
I have written this code that gave me 30 [1*30] matrix
I try to save each matrix [1*30] in different names so I can later combine them in one matrix[30*30] using [mat1;mat;...;]
I tried it using for loop in different ways but i have errors
Can you help me =)?!
**********************************
function C=OneCamera(x,y)
LCamera = 5;
WCamera = 6;
LArea = 5;
WArea = 6;
for x=1:LCamera
for y=1:WCamera
for i=1:LArea
for j=1:WArea
d=(i-x)^2+(j-y)^2;
if d<16
C(i,j)=1;
else
C(i,j)=0;
end;
end;
end
x
y
C
A= reshape (C',1,30)
end
end
end

Don't name your matrix mat1, mat2, mat3,... In your case, you define your matrix as 30x30 and each time you can set the value for each row. See this post http://www.mathworks.com/matlabcentral/answers/143-how-do-i-make-a-series-of-variables-a1-a2-a3-a10

It may not be efficient, but before your "for" loops you can define an empty matrix:
mat = [];
Then inside your "for" loop after you define your 1x30 matrix "A", you would just need to do:
mat(end+1,:) = A;
Is this a possible work around?
For larger matrices you would do well to preallocate the size of the matrix - for example:
mat = zeros(30,30);
Then populate each row of that matrix after each iteration.
