# looking for multiple values in a matrix

Hi guys
I created a code. The purpose of this code is:
It goes to the first row of matrix birfazson. It looks where it says "1" in the first row.
For example, if 1 is written in the fourth, eighth, tenth columns, in the new_m matrix, it writes:
birfazson :
2 7 5 1 6 3 2 1 9 1
5 7 1 4 8 6 9 1 5 1
new_m :
4
8
10
Then I did sum, cumsum etc.
There is something I want to do now.
We performed all these operations by searching for the value 1 in the phaseson matrix.
But I need to perform these operations for the values 2,3,4,5,6,7,8,9,10.
that is, one should look at the value of 2 in the phaseson matrix, write it down somewhere, and perform the sum operation on it as well.
My code is :
result = birfazson(1,birfazson(2,:) == 1).'
new_m = [result birincisure(1,result).']
proctime=[birincisure(1,result).'] ;
Yy = zeros(numel(proctime),3);
Yy(:,1) = proctime(:,1);
Xx = cumsum(Yy(:,1));
Yy(2:end,2) = Xx(1:end-1);
Yy(:,3) = Xx(:);
Do I need to use a for loop to do this? How can I do it?
(My matrices are pretty big, I used small matrices for example)
Please let me know if I wasn't descriptive enough.
(NOTE :This is how I did it, the code became long and complex like this. )
