To calculate value in a uitable

In a uitable table, I have produce a matrix as below:

>> a= [1 1 1 2 2 3 3 3 4 ; 3 3 1 4 4 4 3 1 1; 3 3 2 4 1 1 1 3 2]

a =

 1 1 1 2 2 3 3 3 4 
 3 3 1 4 4 4 3 1 1
 3 3 2 4 1 1 1 3 2

Therefore,in each row, I need to calculate the marks occur based on conditions below:

1. if no 3 occur in three cells continuously therefore the mark charged is 30.
2. if no 3 occur in two cells continuously and then followed by no 1 in the next cell, the mark charged is -20.
3. if no 3 occur in a cell and then followed by no 1 in the next cell, the mark charged is -10.
4. if no 3 occur in two cells continuously and then followed by no 2 in the next cell, the mark charged is -20.
5. if no 3 occur in a cell and then followed by no 2 in the next cell, the mark charged is 0.

Then, in each row, the total marks will calculate. Finally the result will be save in a matrix like this:

marks =

 -30
 -30
 -20

This marks also will total to become an X value as below:

X = -80

How can I code this problem in matlab? Please help me and thank you.

try this code, I cant check now

s = size(a);
b = zeros(s);
b(abs(a - 3) < 1e3*eps) = -10;
k = [true(s(1),1) diff(a,1,2)~=0].*a;
p = arrayfun(@(x)10*nnz(strfind(k(x,:),[3 2])),(1:s(1))');
marks = sum(b,2) + p;

Can you tell me how to find X? Thank you so much...

Hi Yue!

X = sum(marks);
