concatenate different data type matrices

I want to concatenate the following two matrix one matrix is (mxn) that has integer values and another matrix is (nx1) that has double values. I want to join (nx1) in the end of first matrix i.e. mxn. How can I do this. I tried using the following code

MATRIX =
     5     4     3     3     3
     2     3     3     5     4
     4     2     5     3     2
     5     5     3     4     3
MQtranspose =
    0.6154
    0.2222
         0
    0.8889
  if true
    rMATRIX = CAT(2,MATRIX,MQtranspose)
  end

but its giving me error "Undefined function 'CAT' for input arguments of type 'double' ".

lower case, cat(), not CAT().

Thanks. This worked! BUT again the output is

rMATRIX =

    3.0000    2.0000    4.0000    4.0000    2.0000         0
    1.0000    2.0000    2.0000    3.0000    3.0000    0.6667
    1.0000    2.0000    5.0000    1.0000    5.0000    0.4444
    4.0000    3.0000    3.0000    2.0000    3.0000    0.4286

I do not want to convert the integers values to double. only last column should be double not the whole matrix

That is going to be a problem. All the data in one matrix must be the same data type. Cell array can contain different types but that may not be what you want. The default data type for MATLAB numerical is double. You rMATRIX data seems to be double data type although it looks like integer. Take a look at the following example:

>> a=magic(3);b=rand(3,1);
>> cat(2,a,b)

ans =

      8.0000    1.0000    6.0000    0.1576
      3.0000    5.0000    7.0000    0.9706
      4.0000    9.0000    2.0000    0.9572

>> a=uint8(magic(3));
>> cat(2,a,b)

ans =

      8    1    6    0
      3    5    7    1
      4    9    2    1
