how to use horzcat in matlab

In MATLAB, horzcat is a function used to horizontally concatenate arrays. It is used to combine arrays of the same size along their columns.

Here is the syntax for using horzcat:

main.m
C = horzcat(A, B)
18 chars
2 lines

A and B are the arrays that you want to concatenate. C is the resulting concatenated array.

Here is an example to demonstrate the usage of horzcat:

main.m
A = [1 2 3; 4 5 6];
B = [7 8 9; 10 11 12];
C = horzcat(A, B);
62 chars
4 lines

The resulting array C will be:

main.m
1   2   3   7   8   9
4   5   6   10  11  12
45 chars
3 lines

Note that horzcat works only when the arrays have the same number of rows.

Remember to make sure that the size of the arrays is compatible for concatenation when using horzcat.

Hope this helps!
