Is "every run" a function called in a loop? What is returned from each run?
Please give details and examples.

the result is sum of the latest vector of pixels matrix, it doesnt have a loop, the code is quite simple; I=imread('png0015.bmp'); I1=rgb2gray(I); BW=edge(I1,'sobel'); D=bwdist(BW); u=D(480,:); Z=sum(u)/720; Z for every run is a number and i run this for 60 items. i want to save the amount of Z for every run and then avearage this vector.

Create a counter and use every incremented value of it to specify a particular matrix row (or column) or cell array element:
1:
for k1 = 1:N
x(k1) = ... RESULT OF CALCULATION ...;
end
or:
for k1 = 1:N
x{k1} = ... RESULT OF CALCULATION ...;
end
2:
k1 = 1;
while condition = true
x{k1} = ... RESULT OF CALCULATION ...;
k1 = k1 + 1;
end
See the documentation on matrix indexing for details on how to specify rows or columns.
EDIT — To average the vector after you’ve created it, use the mean funciton:
x_mean = mean(x);

If you want to read 60 images, this is one option:
for k1 = 1:60
I=imread('png0015.bmp'); % Read Each Image File
I1=rgb2gray(I);
BW=edge(I1,'sobel');
D=bwdist(BW);
u=D(480,:);
Z(k1)=sum(u)/720;
end
You obviously want to read different image files. There are ways to do that in a loop, but since I have no idea how you named them, I cannot offer specific code to read each one.
