There are no MX array manipulation functions that emulate the HORZCAT functionality of MATLAB. However, it is possible to use the MXREALLOC and MEMCPY functions to achieve the desired functionality. The attached C MEX-file example concatenates two MX arrays using the above functions.
To compile this code in MATLAB, perform these steps:
1. Select a compiler by issuing the following at the MATLAB Command Prompt:
mex -setup
2. Issue the MEX command:
mex mx_concatenate.c
3. To execute this function within MATLAB, issue the following at the MATLAB Command Prompt:
A=rand(5,3);
B=rand(5,2);
C=mx_concatenate(A,B);
The variable "C" is the concatenated array of arrays "A" and "B".
