Get multiple matrices automatically in workspace

Dear,

I run an algorithm 50 times using the for loop. I want to save the results after each iteration ie I want to have in the workspace 50 matrices but I always find the last matrix (for i = 50). I apply this loop on all the algorithm. My algorithm contains Randomized values, every execution I have a matrix. I want to have 50 matrix automatically using the For loop but I find the last one in the workspace. Do you have an idea ?

for j=1:50
X = 200 * rand(1,20) - 100;
Y = 200 * rand(1,20) - 100;
for i=1:20
dist =  sqrt((X(i)-X(:)).^2+(Y(i)-Y(:)).^2);  
distance=[distance dist ];
end
end

DON'T make 50 separate matrices.

You need to learn about arrays, and multi-dimensional arrays. Learn to use arrays. That is what makes MATLAB a useful tool.

Don't do this. Read this to know why:

try this

for j=1:50
X = 200 * rand(1,20) - 100;
Y = 200 * rand(1,20) - 100;
for i=1:20
dist =  sqrt((X(i)-X(:)).^2+(Y(i)-Y(:)).^2); 
end
matrices{j}=dist;
end

with

matrices{n}

you should be able to get the matrix of the n. loop
