MATLAB: Use of horzcat

concatenation

What is the use of horzcat? Is there an advantage of using horzcat over manually concatenating arrays horizontally? for example:

A = {'a','b','c'};
B = {'d','e'};
C = horzcat(A,B);

This is the same as:

A = {'a','b','c'};
B = {'d','e'};
C = [A,B];

So, is there an advatage of using horzcat?

When you type [A, B] in the code, horzcat is called internally, as it is when it is called explicitely also. [.,.] is a synonym only.

cat(2, A, B) replies the same result, but as far as I remember it has a tiny difference in the runtime.

                    Fused_Features = [Extracted_Color_Features; Extracted_Gabor_Features];

Abdulkareem, simply use

 C = [A; B];

where A and B are your 476-by-11 matrices.

 A = [1 2 3; 4 5 6];
 B = [9 8 7; 6 5 4];
 C = [A; B]
 C =
     1     2     3
     4     5     6
     9     8     7
     6     5     4
