concatenate different data type matrices
显示 更早的评论
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().

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
