Horizontally concatenate multiple fi objects
c = horzcat(a,b,...) [a, b, ...]
c = horzcat(a,b,...) is called for the syntax [a, b, ...] when any of a, b, ... , is a fi object.
[a b, ...] or [a,b, ...] is the horizontal concatenation of matrices a and b. a and b must have the same number of rows. Any number of matrices can be concatenated within one pair of brackets. N-D arrays are horizontally concatenated along the second dimension. The first and remaining dimensions must match.
Horizontal and vertical concatenation can be combined together as in [1 2;3 4].
[a b; c] is allowed if the number of rows of a equals the number of rows of b, and if the number of columns of a plus the number of columns of b equals the number of columns of c.
The matrices in a concatenation expression can themselves be formed via a concatenation as in [a b;[c d]].
