Calculate average of multiple matrices by reading an m.file

I'm having difficulty in calculating the mean of multiple matrices. I know how to calculate the mean, I have tried to use mean(match,3) in 3 dimension , but it does not give me the mean of all my matrices by columns If I calculate my mean in the while loop, it creates a mean for every matrix, and if I do it outside the while loop, it does it only for the last matrix.
For example while(reading file) ...
if(some conditions) continue
end
match= strcmp('Hello', out)//compares script with the word hello and outputs a logical array of 1s and 0s
M=mean(match,3)
end
match=[1 0 0 0 0 0] match=[0 0 1 0 0 0] match=[0 0 1 0 0 0]
I want the mean to be M=[1/3 0 2/3 0 0 0]
Do I need to use a for loop? Because it seems to be a much longer process to use a for loop to get the mean, but I do not see how else I could do this.

k = 0;
while (reading file) ...
k = k+1;
match(k,:) = strcmp('Hello', out)
end
M = mean(match)
