I have x=16 * 16 matrix of double values. i need to figure out consecutive values of 'x' which are less than 150 and replace them with the original value plus(+) 8.

>> x = randi(200,16,16);
>> idx = x<150;
>> x(idx) = x(idx)+8;
Very basic MATLAB operations, such as logical indices, as introduced in the Getting Started tutorials, which are highly recommended for all beginners:

How are you defining consecutive? MATLAB goes row by row (down rows), then over to the next column and down its rows. Is that your definition? If so, then is the last element in column 2 consecutive with the first element in column 3?
