How to get row indices of matching pattern

Hi,

I have cell array matrix as below:

Standard      Manual  179  
Standard      Auto    1
Nonstandard   Auto    86  
Nonstandard   Auto    86     
Standard      Manual  179  
Standard      Auto    1 
Standard      Manual  250
Standard      Manual  179  
Standard      Auto    1 
Nonstandard   Manual  179
Standard      Manual  179  
Standard      Auto    1 

I want get the row indices where the it match the given pattern. The given pattern is:

Standard      Manual  250
Standard      Manual  179  
Standard      Auto    1 

The first column should be Standard & second column should be Manual. This pattern should appear twice continuously, next immediate row should be (column 1 & 2) Standard & Auto.

The row indices I desired is the starting row index and end row index. In this example it is 7 & 8.

Try

%%I expanded the example with a couple of edge cases
cac = { 'Standard',     'Manual', 250
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        'Standard',     'Auto',   1
        'Nonstandard',  'Auto',   86 
        'Nonstandard',  'Auto',   86    
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        'Standard',     'Manual', 250
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        'Nonstandard',  'Manual', 179
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        'Standard',     'Manual', 250
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        'Standard',     'Manual', 250
        'Standard',     'Manual', 179 
        'Standard',     'Auto',   1
        };

pattern = { 'Standard',     'Manual', 250
            'Standard',     'Manual', 179 
            'Standard',     'Auto',   1
            };
ixStart = [];
jj = 1;
while jj+2 <= size(cac,1) 
    if all(all( cellfun( @strcmp, cac(jj:jj+2,1:2), pattern(:,1:2) ) ))
        ixStart(end+1) = jj; %#ok<SAGROW>
        jj = jj+3;
    else
        jj = jj+1;
    end
end
% ixEnd = ixStart+2;

"In this example it is 7 & 8." I assume you mean 7 & 9.
