> 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:

It's ok. Found a very simple and short solution. Just use:

XAccelNew = typecast(reshape(XAccel,1,[]),'uint16')';
