Incrementing Variables

Hi, I have an array of unit8 binary numbers. I need to concatenate every 2nd row i.e. the first with the second, the third with fourth etc. and then each of these back to a decimal and have them all in one array. I having trouble finding a way to do this without creating many many new variables. Length of array will vary but will be in the 1000?s. So far I have:

% Convert XAccel to binary (uint8) and flip MSB
XAccelBin = de2bi(XAccel, 'left-msb');

% Concatenate and change first row to a string
XAccelNewFirstRow = num2str([XAccelBin(2,:), XAccelBin(1,:)]);

% Change first row back to decimal
XAccelNewFirstRow = bin2dec(XAccelNewFirstRow);

% Concatenate and change second row to a string
XAccelNewSecondRow = num2str([XAccelBin(4,:), XAccelBin(3,:)]);

% Change second row back to decimal
XAccelNewSecondRow = bin2dec(XAccelNewSecondRow);

XAccelNewestFirstRow = [XAccelNewFirstRow; XAccelNewSecondRow];

Any help would be appreciated.
